I am running vdsm from packages as my interest is in developing for
the
engine and not vdsm.
I updated the vdsm package in an attempt to solve this, now I have:
# rpm -q vdsm
vdsm-4.10.3-10.fc18.x86_64
I'm afraid that this build still does not have the patch mentioned
earlier.
I noticed that when the storage domain crashes I can't even do "df -h"
(hangs)
That's expectable, since the master domain is still mounted (due to that
patch missing), but unreachable.
Would you be kind to try out my little patch, in order to advance a bit
in the research to solve the bug?
I'm also getting some errors in /var/log/messages:
