Symptoms

NDMP backup failing when running a backup for a few projects - but not for others on the NAS.

If the NDMP logs files are checked then you see something like this for the failed projects:

2014-8-6 07:25:07 /usr/lib/ndmp/ndmpd[1143] error error setting property 0.0.u/0.level.r
2014-8-6 07:25:07 /usr/lib/ndmp/ndmpd[1143] error No more space is available
2014-8-6 07:25:07 /usr/lib/ndmp/ndmpd[1143] error cannot set property for 'pool/local/project_name /bakcup_name@some_other_name'--out of space
2014-8-6 07:25:07 /usr/lib/ndmp/ndmpd[1143] error zfs_prop_set: -1

Cause

The 'failing' project shares actually had quotas set on them that were exceeded at the time of the scheduled NDMP backup.

The associated ZFS pool (on the NAS appliance) and the actual top level project did not have any space issues.

Solution

The shares in the Project had space cleared - so they were then below their quota limits.
