NFS stale handle error

The following scenarios can cause problems when connecting to a NAS share.
Scenario 1
1. Create an NFS share and mount it on a Linux box.
2. Delete the share on the StoreOnce System without unmounting it from the Linux box.
3. Recreate the share again with the same name.
In this scenario, the Linux client will assign a new set of inodes to the new share, but when trying to
access the old mount point it will use the previous set of inodes and will therefore not connect.
Scenario 2
1. Create an NFS share and mount it on a Linux box.
2. The service set for the share fails over or fails back without unmounting it from the Linux box.
In this scenario, the StoreOnce NFS server will assign a new set of file handles to the share, but when the
Linux client tries to access the old mount point it will use the previous set of file handles and will therefore
not connect.
For both scenarios, reboot the host Linux system or unmount and remount the NFS share to restore the
connection.

If backup or replication fails

Backup fails
In the StoreOnce System GUI, check the system Events (at the bottom of the navigation tree). One
reason for a backup failure is that the system has insufficient free capacity, as reported by the ISV. A
warning is generated at 70% and at each increase of 5%. After 85% the warnings come at smaller
increases. At 95%, the warnings become alerts and are sent at each increase of 1%. When capacity
reaches 98% full, the system becomes read-only (no new data can be written), however, you can still
delete old data.
Hewlett Packard Enterprise also strongly recommends checking backup application error logs. The
following issues can result in errors:
