<div dir="auto">its an Centos based NFS. Yes I have SELinux permissions nfs_t active. Otherwise sanlock fails immediately after storage domain activation.</div>

<div dir="auto">Maybe another SELinux option or some kind of new locking?</div>

Hi,<br>
<br>
we are currently evaluating NFS 4.2 based storage for OVirt 4.1.2. Normal operation<br>
and discard support work like a charm.<br>
<br>
For some strange reason we cannot use VM live migration any more. As soon as one<br>
NFS 4.2 based VM disk is doing disk I/O during the operation. VM stalls and is paused.<br>
It seems as if qemu on target node cannot take over disk images. See BZ1464787.<br>

<div>Can you make sure you are not suffering from any SELinux issues?</div>
<div>What NFS server are you using? If it's Linux based, it needs some selinux commands.</div>
<div>For example (from ovirt-system-tests):</div>
<div> semanage fcontext -a -t nfs_t '/exports/nfs(/.*)?'</div>
<div> restorecon -Rv /exports/nfs</div>
