Netbackup 7 - Incorrect disk pool available space
I'm currently testing Netbackup 7 in our lab. I created a media server dedup disk pool (on a Win2k8 R2 Std 64 bits server). Backups were working fine until recently. I'm now getting error 129 (insuffisent disk space). After looking at the drive, I only had 18gb left (the drive is 1TB). I went in the catalog and expired a bunch of older backups. My disk space is now back to 120gb but for some reason, Netbackup's disk pool properties still report only 18gb as available space. I've tried restarting services (and even rebooting the server) but nothing changed. I figured maybe it would get updated by one of the admin tasks that runs every night so I left it like that for the week-end but this morning, the console still shows 18gb available space. Is there a way to force Netbackup to recalculate the available space?
Also, on a related note... looking at the disk pool properties, there is a "Disk volumes" section where it reports my 18gb free space. I've search a lot but couldn't find a way to add a 2nd volume to the disk pool (didn't find anything in the admin guide or the console). Since the section has a "s" to volumes, I'm guessing it is doable. Can anyone point me in a direction in case I'd eventually need to add a 2nd lun to the server for additional space?
Thanks a lot for your help!
