Hi everyone
I've set up a gluster storage with two replicated bricks
DC is up and I created a VM to test gluster storage
If I start the VM WITHOUT any disk attached (only one virtual DVD) it
starts fine.
If I attach a gluster domain disk thin provisioning 30 Gb the Vm stucks in
"waiting for launch" state
I see no special activity on the gluster servers (they serve several other
shares with no troubles at all and even the ISO domain is a NFS on
locally mounted gluster and works fine)
I've double checked all the pre requisites and they look fine (F 19 -
gluster setup insecure in both glusterd.vol and volume options -
uid/gid/insecure )
Am I doing something wrong?
I'm even unable to stop the VM from the engine GUI
Any advise?
Which version of ovirt are you using? Hopefully ovirt-3.3.0.1.
For how long is the VM stuck in its "wait for launch" state?
What does `virsh -r list` has to say while startup stalls?
Would you provide more content of your vdsm.log and possibly
libvirtd.log so we can understand what blocks the VM start-up? Please
use attachement of pastebin, as your mail agents wreaks havoc to the log
lines.
Thank you for your answer.
Here are the "facts"
In the GUI I see
"waiting for launch 3 h"

I attach the full vdsm log
Look around 30-10 10:30 to see all what happens
Despite the "terminated" label in output from virsh I still see the VM
"waiting for launch" in the GUI, so I suspect the answer to "how
long" may
be "forever"
Since this is a test VM I can do whatever test you may need to track the
problem included destroy and rebuild
It would be great to have gluster support stable in ovirt!
Thank you for your efforts
The log has an ominous failed attempt to start the VM, followed by an
immediate vdsm crash. Is it reproducible?
We have plenty of issues lurking here:
1. Why has libvirt failed to create the VM? For this, please find clues
in the complete non-line-broken CentOS_30.log and libvirtd.log.
2. Why was vdsm killed? Does /var/log/message has a clue from systemd?
3. We may have a nasty race: if Vdsm crashes just before it has
registered that the VM is down.
4. We used to force Vdsm to run with LC_ALL=C. It seems that the grand
service rewrite by Zhou (http://gerrit.ovirt.org/15578) has changed
that. This may have adverse effects, since AFAIR we sometimes parse
application output, and assume that it's in C. Having a non-English
log file is problematic on it's own for support personal, used to
grep for keywords. ybronhei, was it intensional? Can it be reverted
or at least scrutinized?
