Symptome

Configure NetWorker AFTD on Isilon NFS share fails.
Error: The user 'root (uid=0)' does not own the contents of device '<name>'

Ursache

Since NetWorker Virtual Edition (NVE) does not support NFSv3, Isilon has to enable the NFSv4 along with the default version 3. There is a "root user mapping" setting in NFSv4. By default, the mapping is set to "nobody." This causes the NFS client failing to write on the share. 

Lösung

  1. Log in to the Isilon OneFS admin UI as root. 
  • Click drop down tab "Protocols" -> "UNIX sharing (NFS)" -> Check or highlight the NFS exports sharing Path "<nfs mount>" -> Click Action "View/Edit" -> Click "Edit Export" -> Browse down to "root user mapping" click "Use custom" -> check "Do not map root users" -> Save changes
  • Click drop down tab "Zone settings" -> Ensure that the "Enable NFSv4 no names" is checked. 
  1. Log in to NVE as admin, then switch to root: sudo su - (Alternatively, the below commands can be run as admin, but you must use sudo) 
    Umount the NFS mount, mount it again. 
    1. umount /<mount point>
    2. mount -t nfs <Isilon host>:/ifs/<nfs mount> /<mount point>
NOTE: Create an /etc/fstab entry on the NVE to make the mountpoint persistent across system reboots. The below screenshot is a general example of a persistent NFS mountpoint.

  1. Log in to the NetWorker Management Console (NMC) as the NetWorker Administrator 
    - Configure the AFTD with the device configuration wizard.
