Can you try to run ‘head’ on the file as various related users? E.g. su - sanlock -s /bin/bash  ; head file
Also try as vdsm and qemu users with the above command.

any light how to debug this issue?

I mounted the NFS manually and all looks good, the problem only arises when vdsm tries to access it

Thanks

Hi

I have a brand new installation and I am trying to create a new VM, I have the Linux ISO uploaded to a NFS ISO Storage Domain but the VM refuses to start, I observe following error:


unable to open /rhev/data-center/mnt/LTST-VIRTMAN01:_ovirt_iso/a284c684-bfa2-49a1-b419-e81001b6196e/images/11111111-1111-1111-1111-111111111111/V1003434-01.iso: Permission denied

 have tried to disable selinux just in case but without success.   Any clues?
 

Thanks
