[ovirt-users] Re: Client separation on bridge level

2020-03-17 Thread Hendrik Peyerl 
Thank you for this, I think we can work with this solution (if it works) for 
most VLANs.

We also have a different case where we have the VMs in a Layer2 VLAN for NFS 
Shares from a Storage Pool with no gateways, do you guys maybe have an idea how 
to seperate those VMs?

Thanks,
Hendrik

[ovirt-users] Orphaned ISO Storage Domain

2020-03-17 Thread Bob Franzke 
Greetings all,

 

Full disclosure, complete OVIRT novice here. I inherited an OVIRT system and
had a complete ovirt-engine back in December-January. Because of time and my
inexperience with OVIRT, I had to resort to hiring consultants to rebuild my
OVIRT engine from backups. That's a situation I never want to repeat.

 

Anyway, we were able to piece it together and at least get most
functionality back. The previous setup had a ISO storage domain called
'ISO-COLO' that seems to have been hosted on the engine server itself. The
engine hostname is 'mydesktop'. We restored the engine from backups I had
taken of the SQL DB and various support files using the built in OVIRT
backup tool. 

 

So now when looking into the OVIRT console, I see the storage domain listed.
It has a status of 'inactive' showing in the list of various storage domains
we have setup for this. We tried to 'activate' it and it fails activation.
The path listed for the domain is mydesktop:/gluster/colo-iso. On the host
however there is no mountpoint that equates to that path:

 

[root@mydesktop ~]# df -h

Filesystem   Size  Used Avail Use% Mounted on

devtmpfs  47G 0   47G   0% /dev

tmpfs 47G   12K   47G   1% /dev/shm

tmpfs 47G  131M   47G   1% /run

tmpfs 47G 0   47G   0% /sys/fs/cgroup

/dev/mapper/centos-root   50G  5.4G   45G  11% /

/dev/sda2   1014M  185M  830M  19% /boot

/dev/sda1200M   12M  189M   6% /boot/efi

/dev/mapper/centos-home  224G   15G  210G   7% /home

tmpfs9.3G 0  9.3G   0% /run/user/0

 

The original layout looked like this on the broken engine:

 

[root@mydesktop ~]# df -h

FilesystemSize  Used Avail Use% Mounted on

/dev/mapper/centos_mydesktop-root  50G   27G   20G  58% /

devtmpfs   24G 0   24G   0% /dev

tmpfs  24G   28K   24G   1% /dev/shm

tmpfs  24G   42M   24G   1% /run

tmpfs  24G 0   24G   0% /sys/fs/cgroup

/dev/mapper/centos_mydesktop-home  25G   45M   24G   1% /home

/dev/sdc11014M  307M  708M  31% /boot

/dev/mapper/centos_mydesktop-gluster  177G  127G   42G  76% /gluster

tmpfs 4.7G 0  4.7G   0% /run/user/0

 

So it seems the orphaned storage domain is just point to a path that does
not exist on the new Engine host. 

 

Also noticed some of the hosts are trying to aces this storage domain and
getting errors:

 

The error message for connection mydesktop:/gluster/colo-iso returned by
VDSM was: Problem while trying to mount target

3/17/2010:47:05 AM

 

Failed to connect Host vm-host-colo-2 to the Storage Domains ISO-Colo.

3/17/2010:47:05 AM

 

So it seems hosts are trying to be connected to this storage domain but
cannot because its not there. Any of the files from the original path are
not available so I am not even sure what we are missing if anything.

 

So what are my options here. Destroy the current ISO domain and recreate it,
or somehow provide the correct path on the engine server? Currently the
storage space I can use is mounted with /home, which is a different path
than the original one. Not sure if anything can be done with the disk layout
at this point to correct this on the engine server itself to get the gluster
path back. Right now we cannot attach CDs to VMs for booting. No choices
show up for use when doing a 'run once' on an existing VM so I would like to
get this working so I can fix a broken VM that I need to boot off of ISO
media.

 

Thanks in advance for any help you can provide.

Actually,
I have seen users using anonuid=36,anonguid=36,all_squash  (or whatever were 
the anon user options) which  forces all users on the share to be mapped to 
nfsnobody and that user/group will have uid  of '36'.

It's worth checking the Sinology documentation.

[ovirt-users] Re: Synology NFS confusion

2020-03-17 Thread Justin Willoughby 
You should be able to just mount the share as the root on any of your oVirt
servers to a temp location, say /s-export and do a 'chown vdsm:kvm
/s-export' then umount and try and use the export with oVirt. It should
have the correct owner and group. I've never used Synology but most any NFS
server should allow changing the user and group for the root of the
share/export after it mounted. I have to do the same thing before creating
an NFS Storage Domain so the user and group are correct.

[ovirt-users] Synology NFS confusion

2020-03-17 Thread Shareef Jalloq 
Hi all,

I'm trying to set up a hosted engine on an NFS share provided by a Synology
NAS.  I've been reading the info and threads regarding the requirement that
the share be owned by vdsm:kvm with uid:gid of 36:36, but this seems
impossible to set on modern Synology boxes.

My understanding of DSM is that the user doesn't have control of the UID
and GID of users.  You can ssh in and modify /etc/passwd but these files
are auto-generated from Synology's own scripts so changes here will not
persist across reboots.  Is that correct?

Secondly, having read lots of posts about permissions and various issues
around export settings, why isn't this documented anywhere?  There just
seems to be lots of contradictory posts.  For example, my experience has
been:

 - my Synology vdsm:kvm ids are 1028:65536
 - the permissions on the NFS export are 777, anything else gives
permissions errors in HE setup
 - the hosted engine install went fine with these settings.
 - the nfs-check.py script provided to check the NFS export fails but the
installation still completes.

So are these issues specific to Synology or is the documentation out there
just wrong?

#confused

Cheers, Shareef.

You will need  to give some info about the environment:
Gluster version
Gluster op-version
Gluster Bricks' file system

Have you tried  to write in the gluster volume ?

Anything  in the gluster brick logs (/var/log/gluster/bricks/.log) ?

[ovirt-users] adding new gluster volume

2020-03-17 Thread Jayme 
What if any steps do I need to take prior to adding an additional gluster
volume to my HCI cluster using new storage devices via the oVirt gui? Will
the gui prepare the devices (xfs/lvm etc) or do I need to do that prior?

[ovirt-users] Unable to open oVirt page past login

2020-03-17 Thread Vrgotic, Marko 
Dear oVirt,

One of my Users, working remotely via VPN (10.200.145.169), is having issues to 
load oVirt Dashboard or any other screen past login page.

icmp response time is about 25ms

Tracking ovirt-request-log and server.log I noticed following correlation:

Once User has opened login page, entered credentials and requested page / 
dataCenters in this case: 
https://ovirt-engine.avinity.tv/ovirt-engine/webadmin/?locale=en_US#dataCenters 
following is logged:

[ovirt-users] Several virtual machines all with the same MAC address ?

2020-03-17 Thread Li Xo 
Hello,
I need to replicate some file servers that must have the same MAC address to 
work properly and which will be placed on different VLANs to avoid MAC 
conflicts.
With VMware and VirtualBox this is quite simple and works without particular 
problems but it seems that oVirt does not allow it or I did not find how to 
proceed.
So 2 questions:
- does it is possible ?
- what must be done to allow oVirt to handle it ?
Thanks,
Li

Dear oVirt,

Is there anyone willing and able to assist me in troubleshooting what seems to 
be multiple issues regarding quotas:

  1.  UI Exception each time I add Consumer to Quota.
  2.  User getting warning of not being authorized to ‘ConsumeQuota’ in order 
to AddVM or AddVMFromTemplate, even though User is in Consumers list.
  3.  Fishy quota usage percentage.

I see this strange behavior on all my platforms, so it’s starting to look as a 
bug to me.
Happy to provide any relevant logs or do tests needed.

Kindly awaiting your reply.

[ovirt-users] Storage Domain already attached to a Data Center

2020-03-17 Thread Anton Louw 
Hi All,

I created a little test environment for myself, just to test a few things. The 
initial test I wanted to do was to see if I can create a new HE, add it to a 
different Storage Domain, and then import my existing Storage Domains. 
Everything went through 100%, except for the little option I forgot to select, 
and that is to put the original Data Center in maintenance. Now, when I want to 
import my storage domains, it tells me that the storage domain is already 
attached to a data center. Is there any way that I can remove this storage 
domain from my original data center through one of my nodes? I would power up 
the old HE, but I have powered it off just before deploying a new HE.

I am having the same issue with a node as well, so if there is a way to remove 
the node from the Data Center as well, that would be awesome.

Thanks

Hi,

Thanks for the clarification. I have a followup question tough.

While working around the issue (lack imageio proxy) I ended up creating an
external glance provider. I noticed it is still using the old glance V1
api. Is there a plan to start using the current glance V2 api (in the Open
Stack Image provider) ?

I could not use the built in glance provider since I am behind a
corporate http proxy which is not supported configuration either.

Thanks, Sakari

[ovirt-users] Storage issues on hosted-engine gluster volume

2020-03-17 Thread Dario Pilori 
Dear all,

after a switch failure, our three-host oVirt hyperconverged setup has
strange issues with the gluster replicate-3 volume that contains the
hosted-engine VM.

Basically, after a host is properly rebooted (but not always after
every reboot, it happens quite randomly), the hosted-engine starts,
but it is immediately paused. On the other hosts, it runs perfectly.
After some digging in the documentation, I realized that this is due
to a storage issue. However, the health of the gluster volume is OK,
and forcing heal does not fix the problem.

The only solution (or workaround, I would say) is to reset the brick
on the faulty host and re-format the brick XFS file system.

This leaves me with some questions, which are: Why is the volume
health OK, while it is clearly not OK? If so, which commands do I need
to use to detect gluster issues? And, why is this situation happening?

Any suggestion is appreciated.

Regards,
Dario
