Underlying FS is XFS GlusterFS - glusterfs-3.5.0-2.el6 I'm using CentOS, if this is problem could RHEL packages be used? why CentOS packages are compiled without native glusterfs support?

help with sriov vdsm hook?
by Darrell Budic 12 May '14

12 May '14

Anyone gotten the SRIOV hook to work with Solar Flare 10g cards? Any advice? I've gotten the hooks installed on my host nodes, and added a string to my engine. The card is up in SRIOV "mode" on the host and virtual instances are available. I can see the hooks running in the vdsm logs, but can't tell what they are doing from there. They are not attaching the sriov card instance to my VM though, so I'm at a loss. As an aside, it'd be really nice to have hooks register with the engine and add proper custom strings to the setup. Failing that, some explicit documentation on EXACTLY what string should be used for the hook would be nice. My first pass at it resulted in an improper string that caused my host to crash/hang and reboot when I attempted to start a VM with it the first time. Speaking of which, I added my custom string to UserDefinedVMProperties, not CustomDeviceProperties. Was that correct? Thanks, -Darrell

NFS service not starting after reboot
by Nauman Abbas 12 May '14

12 May '14

Hello all Need some quick help on this. I restarted one of my oVirt nodes and it doesn't seem to go up after that. I have done some troubleshooting and found out that the nfs-server service is not going up. Here's the error. [root@ovirtnode2 /]# systemctl start nfs-server.service Job for nfs-server.service failed. See 'systemctl status nfs-server.service' and 'journalctl -xn' for details. [root@ovirtnode2 /]# systemctl status nfs-server.service nfs-server.service - NFS Server Loaded: loaded (/usr/lib/systemd/system/nfs-server.service; disabled) Active: failed (Result: exit-code) since Mon 2014-04-14 06:43:15 UTC; 18s ago Process: 2751 ExecStart=/usr/sbin/rpc.nfsd $RPCNFSDARGS $RPCNFSDCOUNT (code=exited, status=203/EXEC) Process: 2749 ExecStartPre=/usr/sbin/exportfs -r (code=exited, status=0/SUCCESS) Process: 2747 ExecStartPre=/usr/libexec/nfs-utils/scripts/nfs-server.preconfig (code=exited, status=0/SUCCESS) Apr 14 06:43:15 ovirtnode2 exportfs[2749]: exportfs: can't open /var/lib/nfs/rmtab for reading Apr 14 06:43:15 ovirtnode2 systemd[2751]: Failed at step EXEC spawning /usr/sbin/rpc.nfsd: No such file or directory Apr 14 06:43:15 ovirtnode2 systemd[1]: nfs-server.service: main process exited, code=exited, status=203/EXEC Apr 14 06:43:15 ovirtnode2 systemd[1]: Failed to start NFS Server.

AIO 3.4 on fedora 19 initial errors before coming up
by Gianluca Cecchi 12 May '14

12 May '14

Hello, I have an environment with All-In-One on Fedora 19. Packages version is aligned with oVirt repos up to 3.4.0-1.fc19 I start and shutdown the system every day as it is a personal computer. Storage is composed by two local storage domains. Every time system boots it takes about 7 minutes to have datacenter up. The system has 16Gb of ram and internal disk is an ssd one (one of the storage domains is on a sata disk). I see some errors for some minutes before the DC and storage domains come up. I would like to know if this is expected or if I have some correctable problems as the system comes form several updates up to the current 3.4.0 version. Here you can find relevant logs with latest lines during yesterday shutdown and today lines up to DC has been activated. Thanks in advance, Gianluca engine.log https://drive.google.com/file/d/0BwoPbcrMv8mvQWYwT0wxYXpXeFk/edit?usp=shari… vdsm.log https://drive.google.com/file/d/0BwoPbcrMv8mvN3BSNjRpbjFSTjQ/edit?usp=shari… supervdsm.log https://drive.google.com/file/d/0BwoPbcrMv8mvR01Sby1Pd1ZHNEE/edit?usp=shari…
