We have an open bug on this, the mount to the ISO domain gets stuck and
never returns:
call mount with (u'192.168.201.3:/exports/nfs/iso',
u'/rhev/data-center/mnt/192.168.201.3:_exports_nfs_iso') {'vfstype':
'nfs',
'mntOpts': 'soft,nosharecache,timeo=600,retrans=6,nfsvers=3',
'timeout':
None, 'cgroup': None}
We'll need probably a live system where it reproduces to see where the
mount command gets stuck.
Sounds like an OS issue to me.
BTW, since we are not using the ISO domain, perhaps we should remove its
creation. It'll save time.
(note however that this is the only NFSv3 mount we perform though).
Y.
