multipath configuration for local disks?
by Matthias Leopold 10 Oct '17

10 Oct '17

hi, i'm using three different generations of hardware for my oVirt hypervisor hosts. they are not exactly the "same", but very "similar". - all were installed with oVirt Node 4.1.x installers - all have (2-4) local SSD disks for oVirt Node OS - all were configured with manual partitioning and SW RAID 1 with two SSD disks for oVirt Node OS after initializing the third generation of hosts (with 4 SSD disks) i noticed the difference in multipath configuration for the local disks. suddenly the two OS disks (for RAID 1) are not configured as multipath disks anymore, the unused other two are multipath disks. in the first two host generations the (only) two OS disks (for RAID 1) are configured as multipath disks. after looking at this for the first time and briefly looking into multipath documentation i think that local disks shouldn't be included in multipath configuration at all. i tried to remove the local disks from multipathing (delete from wwids file, explicit blacklisting), to no avail. i'm pasting two listings from the 4 SSD disk situation: # lsscsi --scsi_id -g [0:0:0:0] disk ATA SAMSUNG MZ7LM480 204Q /dev/sda - /dev/sg0 [0:0:1:0] disk ATA SAMSUNG MZ7LM480 204Q /dev/sdb - /dev/sg1 [0:0:2:0] disk ATA SAMSUNG MZ7LM480 204Q /dev/sdc SAMSUNG_MZ7LM480HMHQ-00005_S2UJNX0J102216 /dev/sg2 [0:0:3:0] disk ATA SAMSUNG MZ7LM480 204Q /dev/sdd SAMSUNG_MZ7LM480HMHQ-00005_S2UJNX0J102214 /dev/sg3 # ls -l /dev/disk/by-id/*SAMSUNG* lrwxrwxrwx. 1 root root 9 9.

Ovirt 4.2 Fencing problems
by Maton, Brett 10 Oct '17

10 Oct '17

Hi, I recently upgraded my testlab to oVirt 4.2-pre and have been having some issues. One of which is fencing with Dell Drac 8 remote access cards. The configuration I'm using works fine on my other (4.1.6) cluster... Error: Health check on Host host.example.com indicates that future attempts to Start this host using Power-Management are expected to fail. Fence agent setup for the host appears to be working though: Which logs would be helpful in debugging this issue ? Regards, Brett

I wondered if this is a bug or something else? The log file is in this link https://paste.fedoraproject.org/paste/f~sHprL93BNZ-iJzoFDyww Best Regards

I have collected here the problems I have found and this might be a bit long but help to any of these or maybe to all of them from several people would be wonderful. My version is ovirt node 4.1.5 and 4.1.6 downloaded from website latest stable release at the time. Also tested with CentOS minimal +ovirt repo. In this case, 3. is solved, but other problems persist. 1. Power off host First day after installing ovirt node, it was able to reboot and shutdown clean. No problems at all. After few days of using ovir, I have noticed that hosts are unable to shutdown. I have tested this in several different ways and come to the following conclusion. IF engine has not been started after boot, all hosts are able to shutdown clean. But if engine is started even once, none of the hosts are able to shutdown anymore. The only way to get power off is to unplug or press power button for a longer time as hard reset. I have failed to find a way to have the engine running and then shutdown host. This effects to all hosts in the cluster. 2. Glusterfs failed Every time I have booted hosts, glusterfs has failed. For some reason, it turns inactive state even if I have setup systemctl enable glusterd. Before this command it was just inactive. After this command, it will say "failed (inactive). There is still a way to get glusterfs working. I have to give command systemctl start glusterd manually and everything starts working. Why do I have to give manual commands to start glusterfs? I have used this for CentOS before and never had this problem before. Node installer is that much different from the CentOS core? 3. Epel As I said that I have used CentOS before, I would like to able to install some packets from repo. But even if I install epel-release, it won't find packets such as nano or htop. I have read about how to add epel-release to ovirt node from here: https://www.ovirt.org/release/4.1.1/#epel I have tested even manually edit repolist, but it will fail to find normal epel packets. I have setup additional exclude=collectd* as guided in the link above. This doesn't make any difference. All being said I am able to install manually packets which are downloaded with other CentOS machine and transferred with scp to ovirt node. Still, this once again needs a lot of manual input and is just a workaround for the bug. 4. Engine startup When I try to start the engine when glusterfs is up, it will say vm doesn't exist, starting up. Still, it won't startup automatically. I have to give several times command hosted-engine --vm-start. I wait for about 5minutes until I give it next time. This will take usually about 30minutes and then randomly. Completely randomly after one of the times, I give this command engine shoots up and is up in 1minute. This has happened every time I boot up. And the times that I have to give a command to start the engine, has been changing. At best it's been 3rd time at worst it has been 7th time. Calculating from there it might take from 15minutes to 35minutes to get the engine up.Nevertheless, it will eventually come up every time. If there is a way to get it up on the first try or even better, automatically up, it would be great. 5. Activate storage Once the engine is up, there has been a problem with storage. When I go to storage tab, it will show all sources red. Even if I wait for 15~20minutes, it won't get storage green itself. I have to go and press active button from main data storage. Then it will get main storage up in 2~3munutes.Sometimes it fails it once, but will definitely get main data storage up on the seconds try. And then magically at the same time all other storages instantly go green. Main storage is glusterfs and I have 3 NFS storages as well. This is only a problem when starting up and once storages are on green they stay green. Still annoying that it cannot get it done by itself. 6.Template locked I try to create a template from existing VM and it resulted in original VM going into locked state and template being locked. I have read that some other people had a similar problem and they were suggested to restart engine to see if it solves it. For me it has been now a week and several restarts of engine and hosts, but there is still one VM locked and template locked as well. This is not a big problem, but still a problem. Everything is grey and cannot delete this bugged VM or template. 7. unable to use GPU I have been trying to do GPU passthrough with my VM. First, there was a problem with qemu cmd line, but once I figure out a way to get commands, it maybe is working(?). Log shows up fine, but it still doesn't give functionality I¨m looking for. As I mentioned in the other email that I have found this: https://www.mail-archive.com/users@ovirt.org/msg40422.html . It will give right syntax in log, but still, won't fix error 43 with nvidia drivers. If anybody got this working or has ideas how to do it, would really like to know how it's done properly. I have also tested with AMD graphics cards such as vega, but as soon as drivers have installed, I will get a black screen. Even if I restart VM or hosts or both. I will only see black screen and unable to use VM at all. I might be able to live with the other six things listed above, but this one is a bit of a problem for me. My use of VMs will eventually need graphical performance and therefore I will have to get this working or find an alternative to ovirt..I have found several things that I really like in ovirt and would prefer to use it.

Help - Host unresponsive!
by Wesley Stewart 08 Oct '17

I have a single server that is running ovirt as a host and a storage domain. I ran an update when the GUI told me that there was one. I shutdown all of the VM's, placed the host in maintenance mode and did the update. Upon rebooting the server, I was able to pull my VM's online without any issue, but then, all of a sudden, vm's stopped responding as well as the host. The host is showing as "Down" and I cannot "Activate" it. Also "Maintenance Mode" is greyed out. Storage pools are "down" but eventually come back online, but the host still will not come online. Every few minutes, the host goes to "UP" right before failing and going back "Down". To make it more confusing, like I mentioned before, this is all in one box, so it isn't like their is a network issue between the storage and the host boxes or anything. Currently trying to reinstall the host and see if that helps, but I would very much appreciate any sort of guidance, support or ideas! Fencing failed on Storage Pool Manager OVIRT-Host for Data Center OVIRT-Datacenter. Setting status to Non-Operational. Host OVIRT-Host failed to recover.
