Are people still experiencing issues with GlusterFS on 4.3x?
by Jayme 17 Mar '19

17 Mar '19

I along with others had GlusterFS issues after 4.3 upgrades, the failed to dispatch handler issue with bricks going down intermittently. After some time it seemed to have corrected itself (at least in my enviornment) and I hadn't had any brick problems in a while. I upgraded my three node HCI cluster to 4.3.1 yesterday and again I'm running in to brick issues. They will all be up running fine then all of a sudden a brick will randomly drop and I have to force start the volume to get it back up. Have any of these Gluster issues been addressed in 4.3.2 or any other releases/patches that may be available to help the problem at this time? Thanks!

GPU passthrough
by Darin Schmidt 16 Mar '19

If I'm reading through the documents correctly, you can't use consumer grade gpus such as gtx 1080's and assign them to a VM? I'm trying to do something similar to how Linus used untaid to build several gaming machines from one. Any help would be appreciated. Thanks.

single server, self hosted engine on host, one vm wont start
by abzstrak＠gmail.com 16 Mar '19

16 Mar '19

I'm not an expert with ovirt by any means, I've been running it for about 1.5 years coming from Xen. I have a Vm with 16TiB of storage that will not boot, it has some snapshots that wont remove. The web gui says it finished removing the last snapshot, but I don't think it actually did (took it about 50 hours).... I have no idea what is wrong with the vm that wont boot, it just says it's starting and never actually starts. Eventually I'll get a message that it failed to start. The boot drive of that vm is 16GB. I removed any snapshots from it and was able to clone it to a new disk, make a new vm and attach that disk to the new vm... booted fine. Now, the storage disk is what I really need working, but I do not have enough space to clone it and I cannot unattach it from the flakey vm since it has snapshots... and it seemingly won't remove the snapshots. Right now, I think its actually still maybe attempting to remove the snapshot? in top, I see qemu-img pulling all of one core at about 100%. unfortunately its very very slow because it's only using one core (of 16). This seemed to be a thing, AFAIK, when removing/merging snapshots in that it will only run single threaded... if it takes a while I don't care, I just want to know what's going on. I can't find any logs to look at that tell me that a snapshot removal or merge is ongoing or ever happened. I cannot find any logs that ever stated the progress of any such merge either. Any pointers there? Also, my backup machine died about 2 weeks ago taking its raid 5 with it... of course... I've been busy at work and figured I'd fix or rebuild it in a couple of weeks... so I don't have a good recent backup of my data on this vm, which is why I'm trying to get it to boot up again.

Broken dependencies in CentOS7 hosts upgrading to 4.2.8 from 4.2.7
by Roberto Nunin 15 Mar '19

15 Mar '19

Hi I have some oVirt clusters, in various config. One cluster based on CentOS7 hosts, another based on ovirt-node-ng. While the second was successfully updated from 4.2.7 to 4.2.8, attempts to update hosts of the first one ends with: Error: Package: vdsm-4.20.46-1.el7.x86_64 (ovirt-4.2) Requires: libvirt-daemon-kvm >= 4.5.0-10.el7_6.3 Installed: libvirt-daemon-kvm-4.5.0-10.el7.x86_64 (@base) libvirt-daemon-kvm = 4.5.0-10.el7 Being a CentOS7 installation and not an ovirt-node-ng, I cannot follow the notice in : https://lists.ovirt.org/archives/list/users@ovirt.org/message/AJUBXAIGXVD5U… The only way to have libvirt-daemon-kvm release 4-5-0.10_6.4 (and not 6.3) is to enable CentOS Updates repo. Looking at host-deploy log looks fine, but It's safe to enable that repo ? There is another, safest method to update these hosts to the latest version of 4.2 ? Thanks in advance -- Roberto Nunin

Discard a snapshot
by Mitja Mihelič 15 Mar '19

15 Mar '19

Hi! We have run into a problem migrating a VM's disk. While doing a live disk migration it all went well until "Removing Snapshot Auto-generated for Live Storage Migration". The operation started and got stuck in the "Preparing to merge" stage. The task was visible as an async task for a couple of days, then dissapeared. The snapshot named "Auto-generated for Live Storage Migration" still exists. If we try to start the VM it produces the following error: VM VM_NAME_HERE is down with error. Exit message: Bad volume specification {u'index': 0, u'domainID': u'47ee9bde-4f18-43c2-9383-0d30a27d1ae7', 'reqsize': '0', u'format': u'cow', u'bootOrder': u'1', u'address': {u'function': u'0x0', u'bus': u'0x00', u'domain': u'0x0000', u'type': u'pci', u'slot': u'0x05'}, u'volumeID': u'3b0184b7-5c5d-4669-8b3a-04880883118a', 'apparentsize': '19193135104', u'imageID': u'35599677-250a-4586-9db1-4df8f3291164', u'discard': False, u'specParams': {}, u'readonly': u'false', u'iface': u'virtio', u'optional': u'false', u'deviceId': u'35599677-250a-4586-9db1-4df8f3291164', 'truesize': '19193135104', u'poolID': u'35628205-9fa3-41de-b914-84f9adb633e4', u'device': u'disk', u'shared': u'false', u'propagateErrors': u'off', u'type': u'disk'}. From what I understand the data access path is snapshot->"disk before snapshot". And since the snapshot is corrupted it cannot be accessed and the whole VM start process fails. I believe that the disk before the snapshot was made is still intact. How can we discard the whole snapshot so that are left only with the state before the snapshot was made? We can afford to lose the data in the snapshot. Best regards, Mitja

Migrating VMs from ovirt-4.1.1 to ovirt-4.2.8
by Wood Peter 15 Mar '19

15 Mar '19

Hi, I need to migrate a few dozen VMs from ovirt-4.1.1 to ovirt-4.2.8. I did a few following this procedure: VMs export -> Detach Export domain -> Attach Export to new ovirt -> Import VMs Importing from VMware is one step only process. All I have to do is select VMware for Source in the Import page and then import the VMs I need. I feel like I'm missing something. Is there a way to import VMs from another ovirt deployment similar to import from VMware i.e. without going through Export storage domain? Thank you, -- Peter
