[ovirt-users] Re: IO Storage Error / All findings / Need help.
In my case I am continuing with oVirt node 4.3.8 based gluster 6.7 for the time being. I have resolved the issue by manually copying all disk images to a new gluster volume which took days specially since disks on gluster still don't support sparse file copy. But the threat of a temporary network failure bringing down the complete oVirt setup is a bit too much risk.

My issue is with Gluster 6.7 (the default with oVirt 4.3.7) as is the case with Christian. I still have the failing volume and disks and can share any information required.

[ovirt-users] Re: IO Storage Error / All findings / Need help.
Were you ever able to find a fix for this? I am facing the same problem and the case is similar to yours. We have a 6 node distributed-replicated Gluster, due to a network issue all servers got disconnected and upon recover one of the volumes started giving the same IO error. The files can be read as root but are giving error when read as vdsm. Everything else is as in your case including the oVirt versions. While doing a full dd if=IMAGE of=/dev/null allows the disk to be mounted on one server temporarily, upon reboot/restart it returns to failing with IO error. I had to create a completely new gluster volume and copy the disks from the failing volume as root to resolve this. Did you create a bug report in Bugzilla for this?

[ovirt-users] Re: Using NFS on Gluster
Hi Indivar, I did understand your question correctly, and I suggested the solution for your use case. If you are starting a new oVirt setup, just configure gluster nodes separately, create a volume for engine and share over nfs, then install oVirt hosted engine on one of the nodes and use nfs as the storage. Once engine is up add other oVirt nodes to engine and finally create a new gluster only cluster and add gluster nodes to it to manage gluster volumes. Do note that none of the above would be considered recommend environment for oVirt, a better solution would be to use gluster replica 3 arbiter 1 with arbiter on one of the ovirt nodes. You can configure different network for gluster and oVirt management so that gluster uses 10g while oVirt uses 1g nic.

[ovirt-users] Re: Using NFS on Gluster
Create a new Cluster in oVirt and disable it's "Virt Service" while enabling the "Gluster Service". Then add the gluster nodes to this Cluster and you will be able to manage them using oVirt without using them for virtualization.

https://gerrit.ovirt.org/#/c/98023/1/dashboard/src/helpers/AnsibleUtil.js
Changing the line from:
[ "rpm", "-qa", "gluster-ansible-roles" ], { "superuser":"require" }
to
[ "rpm", "-qa", "gluster-ansible" ], { "superuser":"require" }
resolves the issue. The above code snippet is installed at
/usr/share/cockpit/ovirt-dashboard/app.js on oVirt node and can be
patched by running "sed -i 's/gluster-ansible-roles/gluster-ansible/g'
/usr/share/cockpit/ovirt-dashboard/app.js && systemctl restart
cockpit"

[ovirt-users] Re: New oVirt deployment suggestions
Also I would not create a single bond for use with gluster and management (even on different VLAN), gluster can saturate 4x1Gbe ports easily, specially during healing and this would trigger fencing since engine would start getting timeouts when trying to reach hosts. I would suggest creating 2 bonded interfaces (2 x 1G each), with one dedicated for gluster or get a dedicated 10G nic for gluster.

Thanks Sahina for the update, I am using gluster geo-replication for DR in a different installation, however I was not aware that Gluster snapshots are not recommended in a hyperconverged setup, don't. A warning on the Gluster snapshot UI would be helpful. Is gluster volume snapshots for volumes hosting VM images a work in progress with a bug tracker or it's something not expected to change?

Apparently this is known default behavior of LVM snapshots and in that case maybe Cockpit in oVirt node should create mountpoints using /dev/mapper path instead of UUID by default.

[ovirt-users] Re: Device Mapper Timeout when using Gluster Snapshots
I also noticed that Gluster Snapshots have the SAME UUID as the main LV and if using UUID in fstab, the snapshot device is sometimes mounted instead of the primary LV For instance: /etc/fstab contains the following line: UUID=a0b85d33-7150-448a-9a70-6391750b90ad /gluster_bricks/gv01_data01 auto inode64,noatime,nodiratime,x-parent=dMeNGb-34lY-wFVL-WF42-hlpE-TteI-lMhvvt 0 0 # lvdisplay gluster00/lv01_data01 --- Logical volume --- LV Path/dev/gluster00/lv01_data01 LV Namelv01_data01 VG Namegluster00 # mount /dev/mapper/gluster00-55e97e7412bf48db99bb389bb708edb8_0 on /gluster_bricks/gv01_data01 type xfs (rw,noatime,nodiratime,seclabel,attr2,inode64,sunit=1024,swidth=2048,noquota) Notice above the device mounted at the brick mountpoint is not /dev/gluster00/lv01_data01 and instead is one of the snapshot devices of that LV # blkid /dev/mapper/gluster00-lv01_shaker_com_sa: UUID="a0b85d33-7150-448a-9a70-6391750b90ad" TYPE="xfs" /dev/mapper/gluster00-55e97e7412bf48db99bb389bb708edb8_0: UUID="a0b85d33-7150-448a-9a70-6391750b90ad" TYPE="xfs" /dev/mapper/gluster00-4ca8eef409ec4932828279efb91339de_0: UUID="a0b85d33-7150-448a-9a70-6391750b90ad" TYPE="xfs" /dev/mapper/gluster00-59992b6c14644f13b5531a054d2aa75c_0: UUID="a0b85d33-7150-448a-9a70-6391750b90ad" TYPE="xfs" /dev/mapper/gluster00-362b50c994b04284b1664b2e2eb49d09_0: UUID="a0b85d33-7150-448a-9a70-6391750b90ad" TYPE="xfs" /dev/mapper/gluster00-0b3cc414f4cb4cddb6e81f162cdb7efe_0: UUID="a0b85d33-7150-448a-9a70-6391750b90ad" TYPE="xfs" /dev/mapper/gluster00-da98ce5efda549039cf45a18e4eacbaf_0: UUID="a0b85d33-7150-448a-9a70-6391750b90ad" TYPE="xfs" /dev/mapper/gluster00-4ea5cce4be704dd7b29986ae6698a666_0: UUID="a0b85d33-7150-448a-9a70-6391750b90ad" TYPE="xfs" Notice the UUID of LV and its snapshots is the same causing systemd to mount one of the snapshot devices instead of LV which results in the following gluster error: gluster> volume start gv01_data01 force volume start: gv01_data01: failed: Volume id mismatch for brick vhost03:/gluster_bricks/gv01_data01/gv.

[ovirt-users] Re: hyperconverged cluster - how to change the mount path?
The correct way to allow hosted engine to use other available gluster peers in case of failure of the specified peer is to pass the –config-append option during setup as described https://ovirt.org/develop/release-management/features/sla/self-hosted-engine-gluster-support/ If you want to change that now, then just edit the file /etc/ovirt-hosted-engine/hosted-engine.conf on all hosts and add the following line: mnt_options=backup-volfile-servers=host02:host03 However note that for any new hosted engine deployments, the file has to be manually edited.
