Resolution
Before running a PoolRebuild it is highly recommended that
the latest NSS patch, that can be obtained from https://support.novell.com/filefinder/, be
applied.
To rebuild the volume, type NSS /PoolRebuild=;
ensure that you have a good backup as rebuild can be
destructive.
To rebuild the volume, type NSS /PoolRebuild=
Prior to running a PoolRebuild if you are unsure about the
state of your backups and are concerned that the PoolRebuild may
cause data loss, you can run a NSS /PoolVerify=
and review the PoolVerify log file for errors.
A PoolVerify that completes successfully typically indicates
that a PoolRebuild will also run through successfully.
Please note that there are certain situations where PoolVerify
will report errors and running a rebuild is necessary to fix
these errors.
After the NSS /PoolRebuild the pool is returned to an active
state you will need to mount the volume(s) contained in the pool
again.
If the pool is still broken after the PoolRebuild NSS will
keep it in a maintenance mode state.
Both the REBUILD and VERIFY utilities generate log files in the root of the boot partition (usually C:\); they are calledpoolname_iv_.vlf for the PoolVerify andpoolname_iv_.rlf for the PoolRebuild, and in most cases will be truncated to 8.3 format.
WARNING:
Running a REBUILD is dissimilar to the process of running VREPAIR on legacy volumes: VREPAIR compares data and corrects differences, REBUILD will validate the consistency of a 'master' set of metadata and make other (subset) instances of that data consistant - even if the result is corrupt data that is now consistantly corrupt; Therefore the possibility of data loss exists with REBUILD.
