Hi List,

  I can't get oVirt 4.4.8.5-1.el8 (running on oVirt Node hosts) to connect to an NFS share on a Synology NAS.

  I gave up trying to get the hosted engine deployed and put that on an iscsi volume instead...

  The directory being exported from NAS is owned by vdsm / kvm (36:36) perms I've tried:
  0750
  0755
  0777

Tried auto / v3 / v4_0

  As others have mentioned regarding NFS, if I connect manually from the host with

  mount nas.mydomain.com:/volume1/ov_nas 

  It connects and works just fine.

  If I try to add the share as a domain in oVirt I get

Operation Cancelled
Error while executing action Add Storage Connection: Permission settings on the specified path do not allow access to the storage.
Verify permission settings on the specified storage path.

When tailing /var/log/messages on

When tailing /var/log/messages on the oVirt host, I see this message appear (I changed the domain name for this post so the dots might be transcoded in reality):

Aug 27 17:36:07 ov001 systemd[1]: rhev-data\x2dcenter-mnt-nas.mydomain.com:_volume1_ov__nas.mount: Succeeded.

  The NAS is running the 'new' DSM 7, /etc/exports looks like this:

/volume1/ov_nas      x.x.x.x(rw,async,no_root_squash,anonuid=36,anongid=36)
Did you try squashing to root?


(reloaded with exportfs -ra)


Any suggestions appreciated.

Regards,
Brett
