[ovirt-users] Re: Another illegal disk snapshot problem!
Hi We have the same issue as you, and we are also using vProtect. I have no solution, but I'm very interested in how to address this. Some VM:s we do have managed to remove the illegal snapshots after changing storage for the VM:s disks, but we have 3-4 VM:s that will not want to remove the illegal snapshot. As for us, this issue has escalated the last couple of months. Is it only us who have these issues or does people not take backup of their VM:s? Feels like more people should have these issues. //Magnus From: Joseph Goldman Sent: 08 December 2020 10:57 To: users@ovirt.org Subject: [ovirt-users] Another illegal disk snapshot problem! Hi List, oVirt 4.3 I know there have been threads about this before - but I am unable to find the exact scenario I am facing. I have a VM with 3 snapshots - Active, and 2 dated ones (technically created by vProtect) After trying to do a fresh snapshot in the GUI it failed out and marked one of the old snapshot disks as 'illegal' - then the other tried to follow suit. I tried 'unlocking' the entity using the unlock_entity.sh tool but any action reverts them back to illegal. Following previous advice - I can see the VDSM status is all showing LEGAL: image:23710238-07c2-46f3-96c0-9061fe1c3e0d - c3dadf14-bb4e-45a7-8bee-b9a01fe29ae1 status: OK, voltype: INTERNAL, format: RAW, legality: LEGAL, type: SPARSE, capacity: 107374182400, truesize: 18402942976 - a6d4533b-b0b0-475d-a436-26ce99a38d94 status: OK, voltype: INTERNAL, format: COW, legality: LEGAL, type: SPARSE, capacity: 107374182400, truesize: 21521768448 - 4b6f7ca1-b70d-4893-b473-d8d30138bb6b status: OK, voltype: LEAF, format: COW, legality: LEGAL, type: SPARSE, capacity: 107374182400, truesize: 12617457664 The 2 bold entries are the 'illegal' snapshots.

I also notice the Active Image is not the same image that has a parentid of all 0's so im not sure on the process of possibly deleting the other snapshots and disks cleanly and/or safely. Deleting or any tasks in the gui 100% fails and its at a point that if I shut down the (critical) VM it will not come back on because of these status'. On top of this what is a good way to take a clean, manual backup of current in use disk before I start playing with this in case worse comes to worse I have to try build it as a new server (As at this point I can't trust my vProtect backups) Any help appreciated.

[ovirt-users] Re: VM with illegal snapshots
Hello We have the same issue, and not just one VM, we have about 10-15 VMs that have either snapshots that are illegal or snapshots that is not possible to remove. This have been an issue for quite some time, all since beginning of 4.3 we get "vm with illegal snapshots" almost every week, and most often we can remove the snapshot and all is ok, but now this have escalated quite much and leaves us with customer VM that we may not be able to reboot or that the disk gets corrupted, that have happed a few times. [cid:2c902230-ccb6-4e63-98f6-ea667ba239bf] This is the VM with most snapshots that we are unable to remove any of them. Engine is on 4.3.10 and hosts on 4.3.9 How can i safely remove these snapshots? (I am not super comfortable around database "hacking" so some informative description would be much appreciated.) And how can we eliminate that these things happen?

Hello @strahil The packet drops are frequent, every time i run "ip -s link" on the guest there is new dropped packets, on the hosts it says "0" and in oVirt it says "0". I can run tcpdump on hosts and guests, but i don't know how to capture the dropped packets with tcpdump. There are no RX or TX errors anywhere, not on hosts, guests or switches. The connection drops are completely random, sometimes after a few minutes and sometimes after a couple of hours, really hard to narrow down, but this may be some errors in our customers network, they are investigating it now, so i will come back with that issue is it still persists. @Oliver I tried this, unfortunately still same result, still dropping packets. @Darell I tried increasing the RX and TX buffer on the hosts, but the guests still drop packets. I am using dual 10G, setup in Active-Backup going to two switches, but the second switch is now turned off during the testing to narrow this down.

[ovirt-users] Dropped RX Packets
Hello all! I'm having quite some trouble with VMs that have a large amount of dropped packets on RX. This, plus customers complain about short dropped connections, for example one customer has a SQL server and an other serevr connecting to it, and it is randomly dropping connections. Before they moved their VM:s to us they did not have any of these issues. Does anyone have an idea of what this can be due to? And how can i fix it? It is starting to be a deal breaker for our customers on whether they will stay with us or not. I was thinking of reinstalling the nodes with oVirt Node, instead of the full CentOS, would this perhaps fix the issue? The enviroment is: Huawei x6000 with 4 nodes Each node having Intel X722 network card and connecting with 10G (fiber) to a Juniper EX 4600. Storage via FC to a IBM FS900.

I have 4 hosts with 3 disks each, i want to user as much space as possible but also some redundancy, like raid5 or 6 The 4 hosts are running oVirt on CentOS 7 I have 2 clusters due to some licensing issues, so i cant use ovirts setup of gluster Today i have set it up as follows Type: Disperse Number of Bricks: 1 x (8 + 4) = 12 So i have 3 bricks per host (one brick per disk) But this setup is not working very well, as soon as i get some traffic on the volume this start to fail on the ovirt nodes, loosing connection etc. All hosts are connected via 10G interface So any suggestions on how i would set this up as best is much appreciated.

I have 2 hosts per cluster, and i have 2 clusters, 4 hosts (its an Huawei x6000) I know oVirt don't support disperse, that's why i run gluster outside of oVirt. And doing that i get a bit more freedom with setting up gluster. So what would be an good setup to be able to use as much space as possible and some redundancy with the 4 hosts i have? //Magnus From: Sahina Bose Sent: 16 April 2019 10:55 To: Magnus Isaksson Cc: users Subject: Re: [ovirt-users] Gluster suggestions On Tue, Apr 16, 2019 at 1:42 PM wrote: > > Hello > > I would like some suggestions on what type of solution with Gluster i should > use. > > I have 4 hosts with 3 disks each, i want to user as much space as possible > but also some redundancy, like raid5 or 6 > The 4 hosts are running oVirt on CentOS 7 > I have 2 clusters due to some licensing issues, so i cant use ovirts setup of > gluster I did not quite get this - are you saying you can have only 2 nodes in one cluster? > > Today i have set it up as follows > Type: Disperse > Number of Bricks: 1 x (8 + 4) = 12 Disperse volumes are not supported with oVirt.

Its for storage of VM disks, not OS but like filestorage. I have done a similar setup with distributed replicated arbiter volumes, but i loose so much storage space. Each disk is 6TB, in a raid 5 it would be 66TB, with dispersed ~45TB, with D-R-A it was around 28TB, quite a massive loss. It was an replicated 3 arbiter 1 setup. When i did this i used LVM and set Arbiter volume as a smaller disk, think it was 2TB Like this: H| 12 3 4 - 1| D1 D1 A1 D4 2| D4 D2 D2 A2 3| A3 A4 D3 D3 Followed this: https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.4/html/administration_guide/creating_arbitrated_replicated_volumes - Example 5.10.

[ovirt-users] GlusterFS and oVirt
Hello I have quite some trouble getting Gluster to work. I have 4 nodes running CentOS and oVirt. These 4 nodes is split up in 2 clusters. I do not run Gluster via oVirt, i run it stand alone to be able to use all 4 nodes into one gluster volume. I can add all peers successfully, and i can create an volume and start it with sucess, but after that it starts to getting troublesome.

NVM, Fixed it.
* Changed to a more resent repo
(https://software.opensuse.org/download.html?project=Virtualization=ovirt-guest-agent)
* Uninstalled and removed all files regarding ovirt agent
* Rebooted the machine
* Not sure if this was nessesary, but uncommented “device_prefix =
/dev/virtio-ports/” in /etc/ovirt-guest-agent.conf
* Run: udevadm trigger --subsystem-match="virtio-ports"
* (re)start service
* Works!

The background is that i did set up an FreeIPA server for auth, worked perfectly, but i ran into some problems using that to auth other systems, so i had to setup a new FreeIPA server and added that to oVirt, but now i want to remove the old one, but can not seem to find how.
