vdsm is using mount command. please look at vdsm log and find the mount command that is failing and run it manually to see the mount trace. you can also attach the vdsm log here and we can try to find it :) Dafna On 01/20/2014 09:17 PM, Willard Dennis wrote:

The share is on a Illumos (nee OpenSolaris) box, and uses ZFS's NFS implementation. Here is the output of the "share" command (i.e. exportfs) for this share:
-@storage/ovir /volumes/storage/ovirt-isos anon=36,sec=none,rw ""
I did change the NFS mount options (added the "anon=36", and changed the "sec=" option from "sys to "none"), and now I'm getting a slightly different error:
----- Error while executing action Add Storage Connection: Problem while trying to mount target -----
Any way to get more info on what exactly the propblem is??
