[ovirt-users] oVirt over gluster: Replacing a dead host

2022-07-17 Thread Gilboa Davara

Hello all,

I'm attempting to replace a dead host in a replica 2 + arbiter gluster
setup and replace it with a new host.
I've already set up a new host (same hostname..localdomain) and got into
the cluster.

$ gluster peer status
Number of Peers: 2

Hostname: office-wx-hv3-lab-gfs
Uuid: 4e13f796-b818-4e07-8523-d84eb0faa4f9
State: Peer in Cluster (Connected)

Hostname: office-wx-hv1-lab-gfs.localdomain <-- This is a new host.
Uuid: eee17c74-0d93-4f92-b81d-87f6b9c2204d
State: Peer in Cluster (Connected)

$ gluster volume info GV2Data
Volume Name: GV2Data
Type: Replicate
Volume ID: c1946fc2-ed94-4b9f-9da3-f0f1ee90f303
Status: Stopped
Snapshot Count: 0
Number of Bricks: 1 x (2 + 1) = 3
Transport-type: tcp
Bricks:
Brick1: office-wx-hv1-lab-gfs:/mnt/LogGFSData/brick <-- This is the
dead host.
Brick2: office-wx-hv2-lab-gfs:/mnt/LogGFSData/brick
Brick3: office-wx-hv3-lab-gfs:/mnt/LogGFSData/brick (arbiter)
...

Looking at the docs, it seems that I need to remove the dead brick.

$ gluster volume remove-brick GV2Data
office-wx-hv1-lab-gfs:/mnt/LogGFSData/brick start
Running remove-brick with cluster.force-migration enabled can result in
data corruption. It is safer to disable this option so that files that
receive writes during migration are not migrated.
Files that are not migrated can then be manually copied after the
remove-brick commit operation.
Do you want to continue with your current cluster.force-migration settings?
(y/n) y
volume remove-brick start: failed: Removing bricks from replicate
configuration is not allowed without reducing replica count explicitly

So I guess I need to drop from replica 2 + arbiter to replica 1 + arbiter
(?).

$ gluster volume remove-brick GV2Data replica 1
office-wx-hv1-lab-gfs:/mnt/LogGFSData/brick start
Running remove-brick with cluster.force-migration enabled can result in
data corruption. It is safer to disable this option so that files that
receive writes during migration are not migrated.
Files that are not migrated can then be manually copied after the
remove-brick commit operation.
Do you want to continue with your current cluster.force-migration settings?
(y/n) y
volume remove-brick start: failed: need 2(xN) bricks for reducing replica
count of the volume from 3 to 1

... What am I missing?

[ovirt-users] Ovirt and gluster 9 volume

2021-04-16 Thread eevans

My setup is 3 Centos 7 servers hyper-converged with a 4th stand alone engine 
server. My issue is Ovirt is reading the cluster disk as 49GiB instead of 5.5 
TB is should be. 
One server has a 928 GB raid 5 volume, the second has a 7,7 TB raid 10 volume 
and the third has a 5.5 TB raid 10 volume. How is Ovirt translating this to 49 
GiB??
Here is a link to the screen shots for verification. 
https://1drv.ms/u/s!AvgvEzKKSZHbhLIrRBvQRLmoZOeEyw?e=rO83vw
Logs look good unless I missed something. 
Any help is appreciated.

[ovirt-users] Ovirt 4.4, Gluster with multiple disks

2020-06-08 Thread Mustapha Aissat

Hi all,

I have a small question. How to configure gluster to use multiple disks for
a volume?


[image: image.png]
Do I need to configure a RAID or LVM that group all disks or I can specify
the disks to use in the GUI?

Thank you in advance.
Best regards,
Mustapha AISSAT.

[ovirt-users] oVirt 4.4 gluster single host vm paused due to unknown storage error

2020-05-28 Thread Gianluca Cecchi

Hello,
in environment in subject, I downloaded from glance repository the CentOS 8
image
CentOS 8 Generic Cloud Image v20200113.3 for x86_64 (5e35c84)
and imported as a template.
I created a vm based on it (I got the message: "In order to create a VM
from a template with a different chipset, device configuration will be
changed. This may affect functionality of the guest software. Are you sure
you want to proceed?")
When running "dnf update", during I/O of packages updates the VM went into
pause.

[ovirt-users] ovirt 4.3.7 + Gluster in hyperconverged (production design)

2019-12-23 Thread adrianquintero

Hi,
After playing a bit with oVirt and Gluster in our pre-production environment 
for the last year, we have decided to move forward with a our production design 
using ovirt 4.3.7 + Gluster in a hyperconverged setup.

For this we are looking get answers to a few questions that will help out with 
our design and  eventually lead to our production deployment phase:

Current HW specs (total servers = 18):
1.- Server type: DL380 GEN 9
2.- Memory: 256GB
3.-Disk QTY per hypervisor:
- 2x600GB SAS (RAID 0) for the OS
- 9x1.2TB SSD (RAID[0, 6..]..? ) for GLUSTER.
4.-Network:
- Bond1: 2x10Gbps 
- Bond2: 2x10Gbps (for migration and gluster)

Our plan is to build 2x9 node clusters, however the following questions come up:

1.-Should we build 2 separate environments each with its own engine? or should 
we do 1 engine that will manage both clusters?
2.-What would be the best gluster volume layout for #1 above with regards to 
RAID configuration:
- JBOD or RAID6 or…?.
- what is the benefit or downside of using JBOD vs RAID 6 for this particular 
scenario?
3.-Would you recommend Ansible-based deployment (if supported)? If yes where 
would I find the documentation for it? or should we just deploy using the UI?.
- I have reviewed the following and in Chapter 5 it only mentions Web UI 
https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure_for_virtualization/1.6/html-single/deploying_red_hat_hyperconverged_infrastructure_for_virtualization/index#deployment_workflow
- Also looked at 
https://github.com/gluster/gluster-ansible/tree/master/playbooks/hc-ansible-deployment
 but could not get it to work properly.

4.-what is the recommended max server qty in a hyperconverged setup with 
gluster, 12, 15, 18...?

Thanks,

Adrian

[ovirt-users] [oVirt HC] Gluster traffic still flows on mgmt even after choosing a different Gluster nw

2019-10-16 Thread Stefano Stagnaro

Hi,

I've deployed an oVirt HC starting with latest oVirt Node 4.3.6; this is my 
simple network plan (FQDNs only resolves the front-end addresses):

front-end   back-end
engine.ovirt192.168.110.10
node1.ovirt 192.168.110.11  192.168.210.11
node2.ovirt 192.168.110.12  192.168.210.12
node3.ovirt 192.168.110.13  192.168.210.13

at the end I followed the RHHI-V 1.6 Deployment Guide where, at chapter 9 [1], 
it suggests to create a logical network for Gluster traffic. Now I can see, 
indeed, back-end addresses added in the address pool:

[root@node1 ~]# gluster peer status
Number of Peers: 2

Hostname: node3.ovirt
Uuid: 3fe33e8b-d073-4d7a-8bda-441c42317c92
State: Peer in Cluster (Connected)
Other names:
192.168.210.13

Hostname: node2.ovirt
Uuid: a95a9233-203d-4280-92b9-04217fa338d8
State: Peer in Cluster (Connected)
Other names:
192.168.210.12

The problem is that the Gluster traffic seems still to flow on the management 
interfaces:

[root@node1 ~]# tcpdump -i ovirtmgmt portrange 49152-49664  

   
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

...

and no yet to the eth1 I dedicated to gluster:

[root@node1 ~]# tcpdump -i eth1 portrange 49152-49664
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 262144 bytes

What am I missing here? What can I do to force the Gluster traffic to really 
flow on dedicated Gluster network?

Thank you,
Stefano.

[ovirt-users] oVirt 4.3.3 gluster option cluster.choose-local added to 'Optimize for Virt Store'

2019-04-22 Thread Strahil Nikolov

Hello Community,
can someone tell me why the option cluster.choose-local was added to "Optimize 
for Virt Store" ?Testing my cluster after the patching showed reduced 
performance , due to relying constantly on network instead of using local NVME 
brick.I have checked my older volumes and they did not have that option.

Is there any benefit to not use the local brick ?Any issues to reset that 
option and use local brick for reading ?

Best Regards,Strahil Nikolov

[ovirt-users] Ovirt and gluster deployment - host name

2018-09-11 Thread florentl


Hello,
I want to deploy ovirt (hosted engine) and gluster on three servers. I 
have thought about a configuration but I'm not sure that it's the most 
suitable one.

All the servers have 2 ten gigabit Ethernet nic.
I read that, am besten,  I must dedicate one nic for the storage and 
another one for the system.

So I will have two netnork address space :
- for the system : 192.168.176.0/24 with a gateway configured
- for the storage : 10.255.255.0/24 without a gateway

Inside my hosts file on all the server I will have :
192.168.176.1 server1
192.168.176.2 server2
192.168.176.3 server3
10.255.255.1 gluster1
10.255.255.2 gluster2
10.255.255.3 gluster2

When I start the gluster deployment I will use gluster1, gluster2 and 
gluster3 name. And after the gluster deployment during  the 
hyperconverged setup I will use server1, server2 and server3 name.


May I have your opinion about this deployment  ?
Thanks in advance for the help.

[ovirt-users] ovirt and gluster network config

2018-06-07 Thread william . dossett

Hi,

I have my 5 ovirt nodes up and running and starting to move forward with actual 
ovirt and gluster setup.  

I am using gdeploy for deployment.

the play book fails saying /dev/sdb is blacklisted by filter?  I am following 
the blog up and running on the ovirt site.

It mentioned adding 

# disable multipath
[script2]
action=execute
file=/usr/share/ansible/gdeploy/scripts/disable-multipath.sh

to get it to work, but it does not work.  The script 3 section after this does 
have the 

file=/usr/share/gdeploy/scripts/blacklist_all_disks.sh

in it.

What can I do to get past this? 

Also not sure if I should be modifying the script/play as I don't really want 
an arbitrator host - if I have 5 real hosts all with the same storage in them?  
(10TB in each)  and it only account for 3 hosts, can I add the other two later 
or should I try to modify the playbook to include these initially?  I am sure I 
will be setting this up several times before I get it right, but at the moment 
I can't get past this error.  Any help would really be appreciated!

Thanks

[ovirt-users] ovirt and gluster disk config

2018-05-22 Thread william . dossett

Hey,  been a few years since I looked at ovirt.   3 years probably and at the 
time I was looking for compute and storage all in one -and was advised not to 
basically.  So Hyperconvergence  is now a thing and want to try it out.  I was 
looking at the blog - up and running with ovirt 4.1, but it seems that is 
mostly for a lab setup.  I've got some real hardware I am going to try this out 
on as a PoC, 5 Dell R720s with 12 TB raw storage in each.  Just wondered if 
there was a guide to the hardware setup of my storage that I am missing?  
Should I configure the storage as hardware RAID before I start installing the 
Nodes?  I did setup glusterfs cluster 3 years ago as well but memory fails me 
on how I had the RAID controller setup if at all.

Thanks

[ovirt-users] ovirt 4.1 gluster 3.8 repo no longer exist.

2018-05-22 Thread Edward Clay


While checking for some patches on one of my ovirt systems I found that
the ovirt-4.1-dependencies.repo no longer has a 3.8 version available.
I see newer versions but not sure if I just need to change the following
to point to it or upgrade to 4.2.

baseurl=http://mirror.centos.org/centos/7/storage/$basearch/gluster-3.8/

to

baseurl=http://mirror.centos.org/centos/7/storage/$basearch/gluster-3.10/

or

baseurl=http://mirror.centos.org/centos/7/storage/$basearch/gluster-3.12/

Does anyone have the correct procedure I should follow?

[ovirt-users] ovirt 4.2 gluster configuration

2018-02-14 Thread Edoardo Mazza

Hi all,
Scenario:
3 nodes each with 3 interfaces: 1 for management, 1 for gluster, 1 for VMs
Management interface has it own name and its own ip (es. name = ov1, ip=
192.168.1.1/24), the same is for gluster interface which has its own name
and its own ip (es. name = gluster1, ip= 192.168.2.1/24).

When configuring bricks from Ovirt Management tools I get the error: "no
uuid for the name ov1".

Network for gluster communication has been defined on network/interface
gluster1.

What's wrong with this configuration?

Thanks in advance.

[ovirt-users] oVirt with Gluster upgraded to 4.2: unable to boot vm with libgfapi

2018-01-01 Thread Gianluca Cecchi

Hello,
a system upgraded from 4.1.7 (with libgfapi not enabled) to 4.2.
3 hosts in a HC configuration

Now I try to enable libgfapi:

Before a CentOS 6 VM booted with a qemu-kvm line of type:

 -drive
file=/rhev/data-center/mnt/glusterSD/ovirt01.localdomain.local:data/190f4096-003e-4908-825a-6c231e60276d/images/02731d5e-c222-4697-8f1f-d26a6a23ec79/1836df76-835b-4625-9ce8-0856176dc30c,format=raw,if=none,id=drive-virtio-disk0,serial=02731d5e-c222-4697-8f1f-d26a6a23ec79,cache=none,werror=stop,rerror=stop,aio=thread

Shutdown VM named centos6

Setup engine
root@ovengine log]# engine-config -s LibgfApiSupported=true
Please select a version:
1. 3.6
2. 4.0
3. 4.1
4. 4.2

[root@ovengine log]# engine-config -g LibgfApiSupported
LibgfApiSupported: false version: 3.6
LibgfApiSupported: false version: 4.0
LibgfApiSupported: false version: 4.1
LibgfApiSupported: true version: 4.2

Restart engine

[root@ovengine log]# systemctl restart ovirt-engine
[root@ovengine log]#

reconnect to web admin portal

Power on the centos6 VM
I get "Failed to run VM" on all the 3 configured hosts

Unfortunately it is not yet there. All the hard work is done and i hope it
will be in 4.1.5 release.

You will be able to enable it with command

engine-config -s LibgfApiSupported=true

I would like to emphasize once more - is it not supported yet and command,
mentioned above, will not do anything useful right now.

See also this page

and the "Open Issues" part that points to bugzilla entries.
It seems it is ON_QA and we are near there for 4.1.5 and VDSM 4.19.25

It will reach 4.1.x at some point, it's still in the works. It'll be
enabled via an engine-config parameter.

[ovirt-users] Ovirt 4.1 gluster with libgfapi

2017-08-02 Thread TranceWorldLogic .

Hi,

I was going through gluster document it was talking about libgfapi, that
gives better performance.
And I also went through many bug description and comment and mail thread in
ovirt group.

But still not understood, how to enable libgfapi ?
Is it supported in 4.1 ? I am confuse.

Please help me to understand whether it supported or not.
If supported, then how can I enable it ? or use it ?

Thanks,

Hi kasturi

Data storage domain is already created and activated. I've also created one

This is the strange behavior, as wrote in my previous, hosted_storage is still 
locked and hosted engine VM is visible only as number of VM, but is not visible 
selecting the host where it is running.

The hosted_storage is still locked.

How to enable the “Hosted Engine” Host property in the web UI or to force 
deploy via CLI ?

If logs are needed, please let me know which one. Attached agent-ha.log (from

Apart this, seems that the test environment is working as expected (Gluster ok,

2017-03-15 Thread knarra


Hi Roberto,

Hosted Engine tab is visible only after hosted_storage and 
hosted_engine vm is imported to the cluster. Once the first node is 
installed, you will need to create a storage domain of vmstore or data 
volume . Once one of these storage domains are created, hosted_storage 
and Hosted_engine vm is imported automatically. After this you will be 
able to see Hosted Engine tab in the New hosts dialog box.


Thanks

Now I need to activate all the remainder 5 hosts for the hosted 
engine, but I haven’t the tab “Hosted Engine” in the Host properties, 
so I can’t deploy HE via web UI.


Using command line, I have an error :

2017-03-15 16:58:48 ERROR otopi.plugins.gr_he_setup.storage.storage 
storage._abortAdditionalHosts:189 Setup of additional hosts using this 
software is not allowed anymore. Please use the engine web interface 
to deploy any additional hosts.


RuntimeError: *Setup of additional hosts using this software is not 
allowed anymore. Please use the engine web interface to deploy any

ENV BASE/exceptionInfo=list:'[(,

additional hosts.',), )]'


The hosted_storage is still locked.

How to enable the “Hosted Engine” Host property in the web UI or to 
force deploy via CLI ?


If logs are needed, please let me know which one. Attached 
agent-ha.log (from first node) and ovirt-hosted-engine-setup.log (from 
host where attempt to deploy hosted-engine via CLI).


Apart this, seems that the test environment is working as expected 
(Gluster ok, installed VM ok).


TIA

oVirt is automatically detecting the available bricks and generating the
backup-volfile-servers option when connecting to a gluster storage domain.

You can see if this worked in vdsm.log, the backup-volfile-servers option
should appear in the mount command.

Please attach vdsm.log showing the time you connected to the gluster
storage domain, and the time of the failure.

Attach also /var/log/sanlock.log - this is the best place to detect issues
accessing storage as it reads and writes to all storage domains frequently.

I created it with Path ovirt1-ks.test:/gv1 and all works fine, until 
ovirt1 goes down.

Then ALL VMs pause till ovirt1 comes back up.
Do I have to list all nodes in the path for this to work?

Path: ovirt1-ks.test:/gv1 ovirt2-ks.test:/gv1 ovirt3-ks.test:/gv1

Or how do I prevent ovirt1 from being single point of failure?


Which type of storage domain have you created - NFS or GlusterFS?
With NFS, this could be a problem, as the nfs server running on ovirt1 
can become single point of failure. To work around this, you will need 
to set up HA with CTDB or pacemaker/corosync depending on version of NFS 
you're using.


If you're using glusterfs, did the hypervisor node go down as well when 
ovirt1 went down? Only during mounting of the storage domain (either on 
activate of hypervisor host/ reboot of host) is the server provided in 
path required to access volume (ovirt1). You can provide 
backup-volfile-servers=ovirt2-ks:ovirt3-ks in Mount options while 
creating the storage domain.


Please also provide output of gluster volume info. (I'm assuming the 
bricks on the remaining servers were online)






Thanks.

[ovirt-users] ovirt and gluster storage domain HA testing

2016-02-16 Thread Bill James

I have a ovirt cluster with and system running ovirt-engine 3.6.2.6-1 on 
centos7.2

and 3 hardware nodes running glusterfs 3.7.6-1 and centos7.2.
I created a gluster volume using gluster cli and then went to add a 
storage domain.


I created it with Path ovirt1-ks.test:/gv1 and all works fine, until 
ovirt1 goes down.

Then ALL VMs pause till ovirt1 comes back up.
Do I have to list all nodes in the path for this to work?

Path: ovirt1-ks.test:/gv1 ovirt2-ks.test:/gv1 ovirt3-ks.test:/gv1

Or how do I prevent ovirt1 from being single point of failure?


Thanks.
