[Networker] FYI - NetWorker 7.5.x and deleting savesets from ADV_FILE devices
2009-04-26 21:19:07
Hi everyone,
Just a heads up about a new feature I've discovered in NetWorker 7.5.x
that may affect you if you're using disk backup units.
A lot of administrators when using disk backup units will periodically
use nsrmm to delete savesets from the disk backup unit under certain
circumstances - e.g., a big manual job that wasn't needed, a failed
full that's going to be re-run, etc.
Usually the procedure has been:
nsrmm -d -S ssid
nsrim -X
or
nsrmm -d -S ssid
nsrstage -C -V volume
This *does not work* any more in 7.5.1. (Not sure about 7.5. Not going
to test, either.)
Instead, when it comes to the purge operation, NetWorker reports that
it's been unable to reclaim space from the disk backup unit because
it's been unable to find details about the deleted saveset(s).
As a workaround, you can instead do the following:
nsrmm -w now -e now -S ssid
nsrim -X
This will mark the saveset as immediately recyclable and then the
subsequent nsrim will trigger safe disk cleanup.
Cheers,
Preston.
