Windows VMs pause ofte when disk images are located on CephFS storage

Hey guys, I have tried to write on the IRC channel, regarding this issue, but I'm no sure if I'm not doing it right or maybe there are not many people watching the #ovirt channel. We have deployed a 6 node oVirt cluster, and have moved roughly 100 VMs on them. We started the cluster with NFS storage, which we were building and testing with our Ceph cluster. The Ceph has been ready for a few months now, and we have tested running oVirt VMs on it using RBD, CephFS and by using the NFS Ganesha server which can be enabled on Ceph. Initially I tested with RBD using the cinderlib functionality in oVirt. This appears to be working fine, and I can live with the fact tha live storage migrations from posix storage are not possible. The biggest hurdle vi encountered are, that the backup APIs in oVirt cannot be used to create a backup and download the backups. This breaks our RHV Veeam backup solution, which we have grown quite fond of. But even my homegrown backup solutions from earlier don't work either, as they use the APIs. For this reason we have now changed to CephFS. It has a different set of problems, as we can only supply 1 monitor when mounting the CephFS storage, making i less robust as it should be. It is also making metadata storage dependent on the MDS. As far as I understand, is data access still connecting to the OSDs where it resides directly. I have multiple MDS containers on the Ceph cluster for loadbalancing and redundancy, but it still feels less tidy than RBD with native Ceph support. The good thing is, that as CephFS is a POSIX filesystem, the backup APIs work and so does Veeam backup. The biggest problems I am struggling with, is the unexplained pausing of exclusively VMs running the Windows Operating system. This is why I didn't notice issues initially, as I have been testing the storage with Linux VMs. The machines pause at a random moment in time with a "Storage Error". I cannot resume the machine, not even using virsh on the host it is running on. The only thing I can do is power it off, and reboot. And in many cases, it then pauses during the boot process. I have been watching the VDSM logs, and couldn't work out why this happens. When I move the disk to plain NFS storage (not on Ceph), this never happens. The result is that most Windows based VMs have not been moved yet to CephFS. I have 0 occurrences of this happening with Linux VMs, of which I have many (I think we have 80 linux VMs vs 20 Windows VMs). The Ceph cluster does not show and problems before, during or after this happening. Is there anyone with experience wih oVirt and Ceph, that can share experiences or help me find the root cause of this problem? I have a couple of things I can progress wih: 1. Move a couple of Windows VMs to RBD, and install a Veeam agent on the servers instead. This is just opening a new can of worms, as it requires some work on the servers each time I add a new server and I also need to make network openings from the server to the backup repos. It is just a little less neat than the RHV Veeam backup solution using the hypervisor. 2. Move a couple of Windows VMs to the NFS Ganesha implementation. This means ALL traffic is going through the NFS containers created on the Ceph cluster, and I loose the distributed nature of the oVirt hosts talking direcly to the OSDs on the Ceph cluster. If I was to go this way, I should probably create some NFS Ganesha servers that connect to Ceph natively on the one end and provide NFS services to oVirt. Both tests would still test Ceph, but using an alternative method to CephFS. My preferred solution really is 1., was it not for the backup APIs being rendered useless. Is work still being carried out on development in these areas, or has oVirt/Ceph development ceased? Thoughts and comments are welcome. Looking forward to sparring with someone that has experience with this :-) With kind regards Jelle

RHEL 9 (rocky/centos/..) guest console problem
by marek 15 Jun '23

15 Jun '23

hi, i know spice/QXL is deprecated so, i have guest VM with console config VGA/VNC (tried Bochs/VNC too) virt-viewer from windows cannot connect to console ("console" button in ovirt admin) if i use VNC params from "console.vv" i can connect to it with tigerVNC client (tightVNC does not work) any ideas what can be wrong? btw is there option to prolong password in console.vv? there is note in the file "# Password is valid for 120 seconds."

self-hosted engine with Local Storage
by Jorge Visentini 14 Jun '23

14 Jun '23

Hello. I know that there is no logic, that there is no HA, redundancy and all that... but is there any possibility that I can deploy the oVirt self-hosted engine using an array of local disks on the host? *In my scenario I don't need to have HA.* *What I need:* 1 host with a self-hosted mechanism on a local domain store, that's all. On this host I will locally run some old VMs. Isolated VMs. -- Att, Jorge Visentini +55 55 98432-9868

oVirt 4.4 - High Performance VMs with Direct LUN attached disks pause when an upstream SAN path failed
by angus＠ajct.uk 14 Jun '23

14 Jun '23

Hello Our SAN engineer performed some maintenance during which time the KVM host lost 2 of the 4 paths to storage. My High Performance VMs with Direct LUN disks with SCSI-Pass-Through enabled paused and had to be rebooted resolve. Other VMs (not High Performance, no Direct LUN disks) on the same host were unaffected. What do you think? Thanks Angus

how to expand a arbitrated-distributed-replicated volume

Hello all, how can I expand a arbitrated-distributed-replicated volume without adding additional arbiter bricks? my current gluster config is: Volume Name: data Type: Distributed-Replicate Volume ID: dcf75cf7-1937-4ce9-a7d0-46a56a3be4b4 Status: Started Snapshot Count: 0 Number of Bricks: 3 x (2 + 1) = 9 Transport-type: tcp Bricks: Brick1: gl1.lan:/gluster_bricks/sdc/sdc Brick2: gl2.lan:/gluster_bricks/sdc/sdc Brick3: gl3.lan:/gluster_bricks/sdx/sdx (arbiter) Brick4: gl2.lan:/gluster_bricks/sdd/sdd Brick5: gl3.lan:/gluster_bricks/sdc/sdc Brick6: gl1.lan:/gluster_bricks/sdx/sdx (arbiter) Brick7: gl3.lan:/gluster_bricks/sdd/sdd Brick8: gl1.lan:/gluster_bricks/sdd/sdd Brick9: gl2.lan:/gluster_bricks/sdx/sdx (arbiter)

Non responsive host (4.3.10)
by Maria Souvalioti 08 Jun '23

08 Jun '23

Hello everyone! Due to a recent major power outage in my area I now have an unresponsive self hosted host in an environment of 3 self hosted hosts. There's one vm stuck on there as well as some metadata I guess from when hosted engine was running there (before the power went down). I'm running 4.3.10 ovirt node with 3 nodes and GlusterFS, no arbiter, and I'm using it to provide services to our clients i.e. DNS, web sites, wikis, ticketing etc. and I cannot shut them down. The ovirt engine is up and running and I can manage all the other VMs that run on the other hosts through the web gui. The unresponsive host replies only to ICMP requests; in every other sense it's dead, no ssh, no gluster bricks, no console, nothing. I tried to place the faulty host in maintenance, using the option to stop glusterd, but wasn't able to as the engine won't let the host go into maintenance mode because it thinks the host has running VMs on it. The host won't go into maintenance even if I chose the "Ignore gluster quorum and self-heal validations" option. I spent last week creating a backup environment were I copied the VMs, to have somewhere to run them in case something goes terribly wrong with the systems or the gluster in the production system. I'm thinking of using the global maintenance mode and then shutting down the engine itself with *hosted-engine --vm-shutdown* and rebooting the affected host. Should I remove the host from the cluster and then re-add it or should I do something else? Thanks for any of your help!
