[ovirt-users] Re: Backup/restore of Hosted Engine VM

2022-09-27 Thread Strahil Nikolov via Users
Another option is to shutdown the Engine and create a Gluster snapshot.Yet, 
this requires Gluster with thin-LVM based bricks.

Is anyone doing Libvirt snapshot or any other similar thing to back up ovengine 
VM?
 
Part of that is the XML of the HE VM should be intact, so currently I am 
consideringhttps://libvirt.org/kbase/live_full_disk_backup.html#full-backup-with-older-libvirt-versions

2022-09-21 Thread Strahil Nikolov via Users
It's just a guess until there is a proof in the gluster's top 
read-perf/write-perf .
Can you share atleast the read-perf ?
I'm pretty confident that the issue is not network-related , as the 
cluster.choose-local requires all reads to be local (reducing the network 
usage).

Thank you very much for your analysis, if I understood the problem is that the 
consumer SSD cache is too weak to help in times under a smoll number ~15 not 
particularly IO intensive VMs, so the IO hangs as the performance is poor and 
this hangs the VMs. The VMs kernel think that the CPU had hanged and so it 
crash.

This seem to be the case

If it's possible would be very useful a sort of profiler in the gluster 
enviromnent that raise up the evidence of issue related to speed of the 
undelying storage infrastructure, it can be a problem related to disks or to 
network, in any case the errors reported to user are almost misleading as it 
seem there is a data integrity issue (cannot read... or something like this.

[ovirt-users] Re: Gluster setup for oVirt

2022-09-18 Thread Strahil Nikolov via Users
It's not outdated but it's rarely necessary because:- the HostedEngine volume 
must be dedicated for the HE VM. Setting enough space for the bricks is enough 
- for example physical disk is 100GB, Thinpool is 100GB, thin LV 84GB (16GB 
should be put aside for the metadata). In such configuration, you can't go out 
of space.I/O overhead can be minimized by setting the full stripe size (and the 
thinpool chunk size) between 1MiB and 2MiB (preferably in the lower end).
One big advantage of the thinpool-based bricks is that you can create snapshots 
of the volume. Usually I shut down the engine, snapshot the volume and then 
power up and do the necessary actions (for example Engine upgrade).

I hope you do realize that modern consumer SSDs have a small cache (at least 
according to  https://www.storagereview.com/review/samsung-860-evo-ssd-review ) 
and we can't rule out the disks.
Use gluster's top command to view the read (17.2.6) and write (17.2.7) 
performance of the bricks before (regular usage),  during (high load)  and 
after the backup (regular usage):

[ovirt-users] Re: Migrating VM from old ovirt to a new one

2022-09-18 Thread Strahil Nikolov via Users
Stop the Storage domains in oVirt and attach the same Gluster volumes on the 
new cluster.Then Import the templates and the VMs from the new engine. Keep in 
mind that you might need to delete all VMs' snapshots and if needed to import 
the same VM as many times as the number of disks those VMs have.
I would give a try to this one as theoretically might work:- revert the time on 
all hosts- block NTP- power on the engine. Then you can try to regenerate all 
certs and shutdown again to fix the time.

Set it back to the original value .
The option picks the local brick for reading instead of picking the fastest one 
(which could be either a remote or a local one) which could help with bandwidth 
issues.

Can you provide details about the bricks like HW raid/JBOD, raid type 
(0,5,6,10), stripe size, stripe width , filesystem (I expect XFS but it's nice 
to know) ,etc.
Also share the gluster client log from the node where the backup proxy is. 
Should be something like: 
/var/log/glusterfs/rhev-data-center-mnt-glusterSD-:_gv1.log

Are you sure you have proper A/ and PTR records for the OLVM nodes and the

If not, use proper entries in /etc/hosts before trying again.

after while, I retried the same cat, and the host console hanged so, 
sometimes, gluster revoke access to file ?!?!?! why?

I think this "hang" is the source of all my problems.

I would check the libvirt and vdsm logs on the receiving host.
Have you tried if pinging the VM (from a 3rd system) helps ?

I have two ovirt clusters.
1. 4.3 cluster with single node (was 3 nodes in the past)
2. 4.5.2 cluster with 3 nodes. the problem was also on oVirt-4.5 node with a 
matching engine version but the cluster configured on version 4.6 because I did 
have a problem upgrading one of the nodes, I also lost the engine because of 
gluster volume sync issue between the hosts, so I formatted the problematic 
node using the 4.5.2 node iso and created a new engine on it, and attached 2 of 
the existing nodes and did upgrade on the nodes using the new engine.

About the new cluster:
1. migration between hosts - almost all the time looks like it succeeds, but 
the VM is not responding after the successful migration.
2. run reboot inside of the VM - in a high percent of the time it just hung 
instead of reboot. With 100% CPU. In status "Reboot in Progress", but after 
some time the status changed to "Up" incorrectly. I tried on the clean images 
of ubuntu and centos from ovirt-image-repository. I imported a server from the 
4.3 cluster to the new cluster, on the old cluster it reboots correctly but in 
the new cluster it doesn't. I tried it both with gluster and with nfs.

Any idea how to solve both problems?

im running an oVirt 4.2.8 cluster with two nodes. A few days ago, my SSL 
certificates expired. After that, i changed all the certificates on the engine 
via "engine-upgrade" command and issued new vdsm client certificates. Then i 
copied the new certificates to my ovirt nodes and restarted vdsmd (systemctl 
restart vdsmd). 




Now i'm still not able to connect to my ovirt nodes. In the engine log i can 
see the following error:

I searched my vdsm client config but i cannot see any specific TLS version set 
(every option with TLS is commented - seems to be the default): 




###




$grep -R -i TLS /etc/vdsm/

/etc/vdsm/vdsm.conf:# ssl_protocol = tlsv1

/etc/vdsm/vdsm.conf:# https://docs.python.org/2/library/ssl.html. e.g. 
OP_NO_TLSv1,

/etc/vdsm/vdsm.conf:# OP_NO_TLSv1_1 By default tlv1, tlsv1.1 and tlsv1.2 are 
enabled.




###




On the engine i didn't find any setting to set a specific TLS version - there 
seems to have been a setting (VdsmSSLProtocol) but that got deprecated years 
ago. 




Does anybody know why my engine is still not able to connect to the client 
vdsmd?




I also tried to set "ssl_protocol = tlsv1" via vdsm.conf but that didn't work 
... 




Thanks

Kilian

I have continuos VMs hangs, even hosted-engine, this give full of troubles as I 
have continuous hangs by hosted-engine and this happen asyncrounosly even while 
there is management operation on VMs (mobility, cloning...)

after a while it happens that the VM is freed but in the VMs I have in console

[ovirt-users] Re: GlusterFS Network issue

2022-08-18 Thread Strahil Nikolov via Users
Yes.Keep in mind that the bricks (hostname/ip+mountpoint combo) should be part 
of the Gluster network. The IP you use while mounting is used only to retrieve 
the volume info (and the bricks) while the brick FQDN/hostname/IP is used for 
the actual data transfer.If you use LACP, you can combine all 4 ports (of 
course you can use VLANs) and simplify the setup.10GBE is recommended, but 
faster is better.

[ovirt-users] Re: Getting to know oVirt

2022-08-18 Thread Strahil Nikolov via Users
Hi and Welcome,
- The engine keeps the VM definition in it's database. The VMs are not 
persistent on the host they are running. Even if the engine is completely lost, 
a fresh new engine can import the storage domain and import VMs' definition 
from there.
- None. The Engine UI is self sufficient. You can run some ansible tasks on the 
Engine VM or remotely via the API.- Only as Gluster Storage (replica 1 with 1 
host, replica 3 in all other cases)- The cockpit installer will install Gluster 
via Ansible. Due to recent migration to Ansible Core, some of the GlusterFS's 
ansible modules are not idempotent

[ovirt-users] Re: No "Virtualization" tab on Node cockpit

2022-08-09 Thread Strahil Nikolov via Users
Most probably is a bug. Is there a newer ISO ?If not, try with a version (or 2 
older) .
Best Regards,Strahil Nikolov 
 
 
Hi. I'm new to oVirt.
Trying to install the first node with hosted engine on it.
The node bare install process from the iso image 
(ovirt-node-ng-installer-4.5.1-2022062306.el9.iso) is fine on a Fujitsu server.
Accessing via browser the node cockpit  at port 9090, on the left panel the 
entry "Virtualization" is missing (installing Node version 4.4.6 it was present 
and working), so I can't launch the hosted engine setup via UI.
Trying to deploy via command line ( $ hosted-engine --deploy ), the 
installation process stops with the error:

[ ERROR ] {'changed': True, 'stdout': '', 'stderr': '', 'rc': 1, 'cmd': "[ -r

[ovirt-users] Re: Manager crash

2022-08-09 Thread Strahil Nikolov via Users
If the engine dies , you won't be able to start VMs or make changes like live 
VM migration or network changes. Yet, even if you shut it down, the VMs and 
their hosts will continue to work.

[ovirt-users] Re: Gluster network - associate brick

2022-08-06 Thread Strahil Nikolov via Users
If you wish the Gluster traffic to be over the 172.16.20.X/24, you will have to 
change the bricks in the volume to 172.16.20.X:/gluster_bricks/vmstore/vmstore
The simplest way is to:gluster volume remove-brick VOLUMENAME replica 2 
node3.mydomain.lab:/gluster_bricks/data/data force
# node3umount /gluster_bricks/datamkfs.xfs -f -i size=512 
/dev/GLUSTER_VG/GLUSTER_LVmount /gluster_bricks/datamkdir 
/gluster_bricks/data/datachown 36:36 -R  /gluster_bricks/data/datarestorecon 
-RFvv /gluster_bricks/data
# If you have entries in /etc/hosts or in the DNS , you can swap the IP with 
itgluster volume add-brick VOLUMENAME replica 3 
172.16.20.X:/gluster_bricks/data/datagluster volume heal VOLUMENAME full
#Wait untill the volume heals and repeat with the other 2 bricks.
Of course, if it's a brand new setup -> it's easier to wipe the disks and then 
reinstall the nodes to start fresh .

Logical Networks:

During deployment, I overlooked a setting and on node2 the host was deployed

I suspect because of this I see the following entries on

[ovirt-users] Re: Adding a GlusterFS Storage Domain

2022-08-04 Thread Strahil Nikolov via Users
Using the ovirtmgmt IPs, the client will go over the ovirtmgmt network to reach 
the volume server (or it's backup systems).Once it obtains the brick list, the 
client will connect to the fqdn/ip of the brick's host.
Overall, it doesn't matter as long as connectivity is possible.
Yet, the brick FQDN is more important and it should be resolving to an IP of 
the Gluster Network.
Best Regards,Strahil Nikolov 
 
 
This may seem like a simple question but clarification from the experts 
would be good.

When adding a GlusterFS Storage Domain via the engine, do I use the Gluster 
Storage FQDNs for the Path and backup-volfile-servers mount options

Or

Do I use the ovirt management network FQDNs.

Kind Regards

Simon...

I removed them and then synced gluster hooks in cluster

Also diagnostic step

rpm -qV glusterfs-server

revealed that on one of hosts are some hooks missing

[root@ovirt-hci01 ~]# rpm -qV glusterfs-server
.M...  c /var/lib/glusterd/glusterd.info

missing    /var/lib/glusterd/hooks/1/stop/pre/S30samba-stop.sh

I reinstalled glusterfs-server package there

Well, I do this only to change CPU Type in cluster but now when Gluster 
services are checked and I try to change CPU Type I got

"Error while executing action: Cannot update cluster because the update 
triggered update of the VMs/Templates and it failed for the following: 
HostedEngine. To fix the issue, please go to each of them, edit, change 
the Custom Compatibility Version (or other fields changed previously in

dialog validation. After successful cluster update, you can revert your 
Custom Compatibility Version change (or other changes). If the problem 
still persists, you may refer to the engine.log file for further details."

Strange thing and probably bug - this action disables Gluster services 
checkbox in cluster!!! Will try to report it...

Also I have no idea what is wrong with HostedEngine as there is (as I 
can see) no custom settings on it... but I cannot change for example 
memory on it because "There was an attempt to change Hosted Engine VM 
values that are locked."

You will be able to import the VMs and templates (the VM templates must be on 
the same storage donain) that have no snapshots. If they do have snapshots - 
you will have to delete them (so you won't be able to revert.Network settings

well, it blocks me from any changes on cluster so it is serious

Can you provide the Ansible log ?
Best Regards,Strahil Nikolov 
 
 
An attempt to deploy a new host fails. Deploy I see the following error in 
the deploy log:

192.168.4.17: Failed to connect to host via ssh: root@192.168.4.17 :
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

Despite the fact that the root user logs into the host via ssh from the 
ovirt-engine without any problems.

So I understand that ansible scripts cannot get through ssh.

Do you have any ideas about this?

Yes. The arbiter is useless with only 1 data brick,as it contains only medatata 
and if you have 1 full brick (data + metadata) and 1 arbiter (only metadata) in 
the volume, you could end in a metadata split brain (risk is the same like  
replica 2 volumes) .
Once you have the new data brick , you can revert the process and increase the 
replica count .
gluster volume add-brick VOLUME replica 3 arbiter 1 host1:/path/to/data/brick 
host3:/path/to/arbiter/brick

There is no need to stop the volume, the operation can be done online.
gluster volume remove-brick GV2Data repica 1 
office-wx-hv1-lab-gfs:/mnt/LogGFSData/brick 
office-wx-hv3-lab-gfs:/mnt/LogGFSData/brick force
replica 1 -> remaining copies ( only Brick 2 remains)
When you got a replacement brick define the brick first and the arbiter second 
(don't forget to define the replica 3 arbiter 1 change /I think this notation 
is still valid/ ).

The remove-brick expects the bricks that have to be removed.Yet, you specified 
1 brick, so 2 are left in the volume -> yet you specified 'replica 1'.Define 
both the data brick and the arbiter brick.

Then, just ensure that the glusterd.service is enabled on all hosts and leave 
it as it is.
If it worries you, you will have to move one of the hosts in another cluster 
(probably a new one) and slowly migrate the VMs from the old to the new 
one.Yet, if you use only 3 hosts that can put your VMs in risk (new cluster 
having a single host could lead to downtimes).
To be honest, I wouldn't change DB if it's a productive cluster. If you decide 
to go that one -> make an engine backup before that.

setting single host to maintenance didn't change state of the gluster

well, in my oVirt install there is no way to setup glusterfs services 
during host reinstall. There are only choices to configure firewall, 
activate host after install, reboot host after install and 
deploy/undeploy hosted engine...

I think that gluster related stuff is installed automatically as it is 
configured on cluster level (where in my case are gluster services 
disabled).

Replacing a dead brick in a 2+1 scenario (2 data + 1 arbiter brick) requires to 
reduce the replica to 1 by removing the dead brick and the arbiter.Use the 
force option as you are not using a distributed-replicated volume .

[ovirt-users] Re: Gluster volume "deleted" by accident --- Is it possible to recover?

2022-07-17 Thread Strahil Nikolov via Users
Check if the cleanup has umounted the volume bricks.If they are still mounted, 
you can use a backup of the system to retrieve the definition of the gluster 
volumes (/var/lib/gluster). Once you copy the volume dir, stop glusterd (this 
is just management layer) on all nodes and then start them one by one. Keep in 
mind that nodes to sync between each other , so restarting the nodes 1 by 1 is 
useless.
You can also try to create the volume (keep the name) on the sane bricks via 
the force flag and just hope it will have the data in the bricks (never done 
that).
Best Regards,Strahil Nikolov 
 
 
hi everyone,

I have a 3x node ovirt 4.4.6 cluster in HC setup.

Today I was intending to extend the data and vmstore volume adding another 
brick each; then by accident I pressed the "cleanup" button. Basically it looks 
that the volume were deleted.

I am wondering whether there is a process of trying to recover these volumes 
and therefore all VMs (including the Hosted-Engine).

You can check existing settings like this:

mnt_options : backup-volfile-servers=gluster2:ovirt3, type : he_shared
[root@ovirt2 ~]# hosted-engine --get-shared-config storage --type=he_local   
storage : ovirt2:/engine44, type : he_local
[root@ovirt2 ~]# hosted-engine --get-shared-config storage --type=he_shared
storage : ovirt2:/engine44, type : he_shared
You have to use the --set-shared-config to point to the new Gluster host and 
new backup-volfile-servers in both he_local & he_shared.

Hello

I installed oVirt on 3 servers(hv1,hv2,hv3) with Self Hosted Engine couple 
years ago. Gluster is used as storage for VMs. The engine has its own storage 
volume.

Then I added 3 more servers(hv4,hv5,hv6).

Now I would like to replace the first 3 servers. I added 3 more 
servers(hv7,hv8,hv9). I created new gluster volumes on hv7-hv9, moved disks 
from old volumes.

Now the question is how to migrate engine storage? I decided to do it on 
Gluster level by replacing each of the brick from the old servers(hv1-hv3) with 
new ones (hv7-hv9). I successfully replaced bricks from hv1 and hv2 to hv7 and 
hv8. InoVirt engine storage Domain is created with the path hv3:/engine. I am 
afraid to replace hv3 brick with hv9, to not break the HostedEngine VM. To 
change storage Domain path I need to move it to Maintenance, but it will 
unmount it from all the hosts and HostedEngine will stop working. Is there any 
otherway to change a storage Domain path?

I already changed storage value in /etc/ovirt-hosted-engine/hosted-engine.conf. 
I did something like this:
# on hv7
hosted-engine --vm-shutdown

# on all hosts
systemctl stop ovirt-ha-agent
systemctl stop ovirt-ha-broker
hosted-engine --disconnect-storage
sed -i 's/hv3/hv7/g' /etc/ovirt-hosted-engine/hosted-engine.conf
hosted-engine --connect-storage
systemctl restart ovirt-ha-broker
systemctl status ovirt-ha-broker
systemctl restart ovirt-ha-agent

# on hv7
hosted-engine --vm-start

and now the Hosted Engine is up and running and Gluster engine volume is 
mounted like hv7:/engine

So the main question remains - how to change the engine storage Domain path?

[ovirt-users] Re: oVirt 4.5.1 Hyperconverge Gluster install fails

2022-07-17 Thread Strahil Nikolov via Users
Can you cat this file 
/etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/vg_create.yml
 
It seems that the VG creation is not idempotent .As a workaround, delete the VG 
'gluster_vg_sdb' on all Gluster nodes:
vgremove gluster_vg_sdb
Best Regards,Strahil Nikolov 

 
Hello all,

I am hoping someone can help me with a oVirt installation that has just gotten 
the better of me after weeks of trying.

After setting up ssh-keys and making sure each host is known to the primary 
host (sr-svr04), I go though Cockpit and "Configure Gluster storage and oVirt 
hosted engine", enter all of the details with 
.san.lennoxconsulting.com.au for the storage network FQDN and 
.core.lennoxconsulting.com.au for the public interfaces. Connectivity on 
each of the VLAN's test out as basically working (everything is pingable and 
ssh connections work) and the hosts are generally usable on the network. 

But the install ultimately dies with the following ansible error:

--- gluster-deployment.log -

Try first with a single host. Set it into maintenance and check if the 
checkmark is available.If not, try to 'reinstall' (UI, Hosts, Installation, 
Reinstall) the host. During the setup, it should give you to update if the host 
can run the HE and it should allow you to select the checkmark for Gluster.
Let's work with a single node before being so drastic and outage-ing a cluster.

well, it worked :-) Now all bricks are in UP state. In fact from

the time.

Well... not yet.Check if the engine detects the volumes and verify again that 
all glustereventsd work.
I would even consider restarting the engine, just to be on the safe side.
What is your oVirt version ? Maybe an update could solve your problem.

well, on db side it looks like cluster has gluster_service disabled...

engine=# select virt_service, gluster_service from cluster;
  virt_service | gluster_service
--+-
  t            | f
(1 row)

still don't know why the checkbox is disabled. Would it be safe to

Currently a template creation on my setup, takes around 29m for a 45G image 
when a simple copy over NFS  takes 1m26s over a 10G network which is expected 
since there is roughly as many read as write over the network (4Gbps)

Adding --cache writeback to qemu-img improves from 29m to around 8m but 
according to a prior comment on this mailing list might not work on all

glustereventad will notify the engine when something changes - like a new 
volume is created from the cli (or bad things happened ;) ), so it should be 
running.
 You can use the workaround from the github issue and reatart the 
glustereventsd service.
For the vdsm, you can always run '/usr/libexec/vdsm/vdsmd_init_common.sh 
--pre-start' which is executed by the vdsmd.service before every start 
(ExecStartPre stanza) and see if it complains about something.

it looks like root of the problem is that Gluster service is disabled in 
cluster settings and cannot be enabled. But it was enabled before... 
also I have to manually install vdsm-gluster when I (re)install new 
host, but bricks from this host are in unknown state in admin. Maybe 
vdsm-gluster is not correctly configured? Maybe glustereventsd is not 
running? I am just guessing...

I have no access to other HCI installation so I cannot compare differences.

I would be really happy if someone could tell me what circumstances 
could disable Gluster service checkbox in admin and how to enable it 
again...

[ovirt-users] Re: Dedicated Migration Network

2022-06-16 Thread Strahil Nikolov via Users
You can use the management network for migration and set a threshold to keep 
some bandwidth for the actual management traffic.
Having separate management network would be useful if you have a very large 
cluster and you will have a lot of movement between the nodes.

Good Day All;

I am in the process of assembling a new oVirt cluster and I am wondering if 
there is any benefit to having a dedicated set of nics solely dedicated to VM 
migration. If so, would those nics (bonded) be on their own vlan and subnet or 
would they share a subnet with gluster storage or the management network ? 
Right now i'm planning on the following architecture.

1. Management = 10G X2 Bond per hypervisor host (10.66.0.0/24)
2. Gluster/iSCSI Storage = 10G X2 Bond per hypervisor host (10.244.0.0/24)
3. VM Production Network(s) = 10G X2 Bond per hypervisor host (No IP Range)
4. ?? Possible Dedicated VM Migration

Thank you very much as any input would be greatly appreciated

You don't need to reinstall the whole system.Get an install media, boot from it

Then follow https://access.redhat.com/solutions/3486741 (requires a

If you use Gluster, don't forget to bump the OP version once you are happy with 
your tests.It controls the backward compatibility, but also some internal 
mechanisms and optimizations.

Downgrade is not recommended but as long as you didn't increase the Gluster Op 
version, you can downgrade the packages and restart the services.
Another option is to reapply the last transaction.

Is there a "cleaner" way of reverting the upgrade? 
I assume there are other packages that may have been upgraded that should be

[ovirt-users] Re: oVirt SSH rate limit and disable SSH passwd auth

2022-06-10 Thread Strahil Nikolov via Users
1. Put the engine in a match block where passowrd authentication is possible.
2. Firewalld rate limit has a burst effect so ot will never limit on the third 
attempt. Put a higher value like 10-15 and you will notice that it works.
Usually infrastructure like oVirt ahould not be exposed to the wild (internet).

Hello,

1.
Is it possible to disable ssh root password authentication in a working oVirt 
cluster without any problems? (host and ovirt-engine)

/etc/ssh/sshd_config
PasswordAuthentication no

The SSH public authentication key is set on the host.

2.

I tried setting ssh rate limit using firewall-cmd but it doesn't work for some 
reason. I can log in more than once.

firewall-cmd --permanent --add-rich-rule='rule family="ipv4" priority="-1" 
service name=ssh limit value=3/m accept'
There is best practice for this?

Thanks

[ovirt-users] Re: storage high latency, sanlock errors, cluster instability

2022-06-08 Thread Strahil Nikolov via Users
Usually I would blacklist the Gluster devices by creating the necessary stanzas 
in /etc/multipath/conf.d/blacklist.conf
This way you will keep the situation simple.

For your problem, it's hard to odentify the problem based on the e-mails.What 
are your symptoms ?
To debug GlusterFS, it is good to start from the brick logs 
(/var/log/gluster/bricks) and the current heal status. On a 3-way replica 
volume heals should be resolved by GlusterFS - if not, there is a bug.

The problem I have is, that I don't know where is the root of this 
problem and if recreating would fix the issue in longer terms.

I would start over.Get your backup and restore the engine crom backup.If backup 
is unavailable, deploy a fresh engine and import the storafe domains, Templates 
and then the VMs.
Once you have a working engine, update to latest 4.3 /I think it was 4.3.10 / 
Keep in mind that older versions do not work.
Once you have a 4.3.10, backup and then rebuild a host with EL8. Then you can 
reatore your enginw on that node with the 4.3.10 backup
Next step is to import the rest of the nodes (do not let the same host to be 
managed by more than 1 engine)

2022-05-10 Thread Strahil Nikolov via Users
If you decide to do it, I would do the following:  Verify if there are any 
heals towards the 4.4 node -> If not, proceed.use remove-brick replica 1 mode 
(see gluster volume help) and remove both 4.5 bricks.Then remove the nodes with 
gluster peer detach.Remove gluster 4.5 and install 4.4
Then setup only 1 node's brick (mkfs.xfs-f -i size=512 ...) , peer probe that 
node and expand the volume (add-brick replica 2) .
N.B.: Don't forget to increase the replica count !!!
Wait for the heals to end, peer probe the last node, mkfs.xfs the brick and 
then again add-brick and increase the replica count.

Of course, backups are must when you play with storage :D

[ovirt-users] Re: FC Storage recover

2022-05-09 Thread Strahil Nikolov via Users
According to vdsm, there are some failed multipath paths -> you will need to 
clear them (pure LinuxSystem Administration) as they might cause the real 
symptom.
According to the log there are read errors. You have to figure out why vdsm 
fails to read the LUN.Can you try to 'dd if=/dev/mapper/multipath-wwid 
of=/dev/null bs=10M count=200' and see if it errors out.

In worst case scenario, you can import the Storage domains ,the VMs  
from it and then configure host networking.
Keep in mind that 2 Engines must never manage the same host.

  On Sat, May 7, 2022 at 0:59, Abe E wrote:   Hey All, I 
really dont like spamming the forums but the issues I am having keep changing 
entirely.
I am at the point where I can get much closer to rebuilding my engine although 
my hurtle currently is restoring.

When I restore using my most recent backup it is problematic

Currently I am restoring by:
clean engine install
engine-cleanup
engine-backup --mode=restore --file=ovirt-engine-backup-20220504011012.backup  
--log=restore5.log
engine-setup

Comes up with alot of annoyances as the ID of the old hosted_storage and the 
new one are mismatched in the GUI.
On top of that it is not allowing me to deploy the engine to the 2nd Gluster 
(3rd one keeps deleting its glusters on reboot since 4.3 Upgrade).

Host 1 which runs the hosted engine is not showing as active or unlike, rather 
it is unresponsive, when I tried to enroll certificates it finally accepted but 
failed because it said its missing networks, once added it crashed the engine 
and ha agent wouldnt come up. Now that I think of it, I could have removed the 
extra networks from being required although it still doesnt benefit me here as 
I am unable to deploy or reinstall the 2nd Gluster node and the first one will 
not show its correct state as the host.

Should I just be deploying the DB, or is the full file backup fine? My issue 
here is it takes long to redeploy so the trial an error of failing takes me 
hours as my backup is from 4.5 engine even though my nodes are on 4.4 as 4.5 
keeps causing the catastrophic failure of my whole cluster.

- Install first host and VM using "hosted-engine --deploy"
- In the Engine UI, change Cluster switch type from Legacy to OVS
- Shutdown the engine VM and stop vdsmd on the host.
- Manually change the switch type to ovs in 
/var/lib/vdsm/persistence/netconf/nets/ovirtmgmt
- Restart the host

After this changing my hosted engine don't wont start, it says i have a problem 
with vnet interface, i don't know virtmanager or i don't know vnetuser. When i 
had return back settings from ovs to legacy mode, hosted engine start without 
any problem 

When i had change file  /var/lib/vdsm/persistence/netconf/nets/ovirtmgmt on

ovs switch mode but they say network out of sync. I tryed to migrate hosted

wont migrate.

But according to ovirt-engine-setup-*.log a GettagsByparent_id(v_parent_id

When searching google for " org.ovirt.engine.core.bll.TagsDirector.init()" and

[ovirt-users] Re: CLI Offline Engine Deployment failing to activate storage domain to gluster error 400

2022-05-06 Thread Strahil Nikolov via Users
Gluster virt volume group has 2 options needed for 
oVirt:storage.owner-uid=36storage.owner-gid=36Check you have them, as it seems 
that the virt group (from GlusterFS package) is now missing them. /Maybe a bug 
???/

I would simply chown the file(s) to 36:36 from the gluster mount and try again.
You can run a find to fix it and give it another try.find   
/rhev/data-center/mnt/glusterSD/_ -not -uid 36 -not -god 36 -exec 
chown 36:36 {} \;
Or to be even more safe, you can also set all files in the brick to be 
accessible to the user/group 36.
find /gluster_bricks// -not -uid 36 -not -gid 36  -exec setfacl 
-m g:36:rwx {} \;

find /gluster_bricks// -not -uid 36 -not -gid 36 -exec setfacl

Login over ssh to the SPM, then trigger the Activate button and then copy the 
vdsm log (last one) from the host.Also check with 'multipath -ll  
36005076300808894600a' if all hosts have the multipath device  and 
it's status is good.oVirt refuses to activate if it can't mount a file-based 
storage (NFS, Gluster) or access the LV on the block-based storage domains (FC, 
iSCSI,etc).
Also in the vdsm logs of the SPM should have a clue why it fails to activate.
I'm not sure if oVirt uses SCSI reservations or not, but it's worth checking).

You will have to provide some logs from the SPM.
If you don't use the storage domain (at least this is the impression), try to 
set it into maintenance and activate it again (UI -> Storage domain -> Select 
domain -> Datacenter -> Maintenance).

 I am happy no one answered, was a fun experimenting process but I was able to 
reconfigure the gluster node using an ansible playbook from redhats website.

Instructions for whats needed:
- 
https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure_for_virtualization/1.6/html/maintaining_red_hat_hyperconverged_infrastructure_for_virtualization/scaling#creating-bricks-using-ansible
- Also had to edit the gluster python file in other threads due to vdsm bug in 
4.5.
Incase anyone is wondering, this is the playbook I had to edit with my configs:

# gluster_infra_disktype
# Set a disk type. Options: JBOD, RAID6, RAID10 - Default: JBOD
gluster_infra_disktype: RAID6

# gluster_infra_dalign
# Dataalignment, for JBOD default is 256K if not provided.
# For RAID{6,10} dataalignment is computed by multiplying
# gluster_infra_diskcount and gluster_infra_stripe_unit_size.
gluster_infra_dalign: 256K

# gluster_infra_diskcount
# Required only for RAID6 and RAID10.
gluster_infra_diskcount: 8

# gluster_infra_stripe_unit_size
# Required only in case of RAID6 and RAID10. Stripe unit size always in KiB, do
# not provide the trailing `K' in the value.
gluster_infra_stripe_unit_size: 128

# gluster_infra_volume_groups

gluster_infra_volume_groups:
  - { vgname: 'gluster_vg_sda4', pvname: '/dev/sda4' }

# gluster_infra_thick_lvs
# Variable for thick lv creation
gluster_infra_thick_lvs:
  - { vgname: 'gluster_vg_sda4', lvname: 'gluster_lv_engine', size: '100G' }

# gluster_infra_thinpools
# thinpoolname is optional, if not provided `vgname' followed by _thinpool is
# used for name. poolmetadatasize is optional, default 16G is used
gluster_infra_thinpools:
  - {vgname: 'gluster_vg_sda4', thinpoolname: 
'gluster_thinpool_gluster_vg_sda4', thinpoolsize: '100G', poolmetadatasize:

# gluster_infra_lv_logicalvols

Has anyone ever tried re-installing the node itself and using the ovirt gui to

Best Regards,Strahil Nikolov
 
 
Hi,

We have a 4 node cluster (4.4.10) and a standalone manager.
We attached to this cluster 4 volumes on FC.
Last week we lost the storage canisters (both), but recovered one of them from 
the storage disks. 
Unfortunatly only 3 storages came back from offline.
I see the 4th FC ID, but it's on "Can't Extend" status.
If i check the storages on nodes (lsblk), i can see only the ID not more on 
this 4th storage.

Do you know any recovery tool or any idea for this situation?

Thanks

I never use the UI for Gluster.Most probably you need to go to Storage ->

Do you have a replacement host ? Or a host that will be an Arbiter ?

[ovirt-users] Re: Ovirt engine service fail to start after upgrading from 4.4.9 to 4.4.10

It's most probably the postgresql-jdbc issue.Connect to the engine over ssh and 
downgrade the 'postgresql-jdbc' package.

Most probably it's the postgresql-jdbc issue.
Let's see if the package can be removed (or newer version generated).

There are threads in the mailing list describing the issue.
@Sandro,is there any chance to remove the broken postgresql-jdbc package  (or 
issue a new version with the rollbacked changes ) untill the issue is fixed ?

Best Regards,Strahil Nikolov 
 
 
No matter how many times I tried to install it, I encountered this error 
and I could not find a method for the solution. Do we need to downgrade 
postgresql-jdbc?

Is there a resource-article we can get information about this subject?

2022-04-30 Thread Strahil Nikolov via Users
You need to first replace the host on gluster level (it looks it has/had a 
brick) before ovirt allows you to remove the host.
Can you check if the gluster volumes have a brick from that host ?

2022-04-30 Thread Strahil Nikolov via Users
hosted-engine output and UI are totally unrelated.The output of hosted-engine 
is matching the 'crown' icon in the UI and indicates on which hosts the 
HostedEngine VM can run.In the UI, the host is just a host that is capable of 
running VMs.
You need to remove the host from the UI.
What kind of storafe are you using ?

You can install software via the rpm-ostree . Yet,if this was RHV - you would 
loose support if you install additional software.Keep in mind that oVirt nodes 
are more an appliance than a regular Linux system and such security rules 
should not affect appliances.

Which software I should use? Clamav? 

I can shutdown each single node and can scan but I would prefer to have it as

How did you do this?

Obviously ens192 is not the good interface. Check where the IP is added and use 
that address.

Hello,
 
I’ve researched a bit about this problem, but none of the proposed solutions 
fixed it. I’m trying to deploy Ovirt 4.5.0.1 in my lab, and the installation 
fails with the following error:
 

 
  
 
I’ve even tried to delete the default network bridge (as suggested in some 
articles), but this didn’t help either. The node has 3 network interfaces, and 
the hosts file points only to the management interface.
 
  
 
Thank you,

[ovirt-users] Re: HELP ME! Failed to validate the SSL certificate for localhost:443

You must not use localhost.Check A/ and PTR records for the engine.

Hi,
I'm having an issue with Failed to validate the SSL certificate for 
localhost:443 during Deploy "hosted-engine."

 check the log files, found this error:
"
[TASK] [ovirt.engine-setup: Check if Engine health page is up]
[ERROR] fatal:[localhost -> my_fqdn.domain]:FAILED!=>{"attempts":12, 
"changed":false,"msg":"Failed to validate the SSL certificate for localhost:443.
Make sure your managed systems have a valid CA certificate installed. 
You can use validate_certs=False if you do not need to confirm the servers 
identity but this is unsafe and not recommended.
Paths checked for this patform: /etc/ssl/certs, 
/etc/pki/ca-trust/extracted/pem, /etc/pki/tls/certs, 
/usr/share/ca-certificates/cacert.org, /etc/ansible.
The exception msg was: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify 
failed (_ssl.c:618).", "status": -1, "url": 
"http://localhost/ovirt-engine/services/health"}
"

NOTE: ovirt engine VERSION 
"ovirt-engine-appliance-4.3-20200603.1.0.2.el7.x86_64"

We tried googling to resolve this issue but, unfortunately, unsuccessfully.
Can someone help us to solve our critical issue?

Best regards,
Bunnatee
