Hi,
we are currently evaluating NFS 4.2 based storage for OVirt 4.1.2. Normal
operation
and discard support work like a charm.
For some strange reason we cannot use VM live migration any more. As soon
as one
NFS 4.2 based VM disk is doing disk I/O during the operation. VM stalls
and is paused.
It seems as if qemu on target node cannot take over disk images. See
BZ1464787.
Can you make sure you are not suffering from any SELinux issues?
What NFS server are you using? If it's Linux based, it needs some selinux
commands.
For example (from ovirt-system-tests):
semanage fcontext -a -t nfs_t '/exports/nfs(/.*)?'
restorecon -Rv /exports/nfs
Has anybody else seen similar issues?
Raz?
Y.
Best regards.
Markus
