I am testing the backup capabilities of DSS (using a VMware ESXi 4.1u1 VM) by following the direction from "Setting up data redundancy on DSS V6 within a system". I have 2 virtual disks, one for the data, one for the backup (no HW/SW RAID, just volumes). When I get to the section on labeling tapes, I select the VirtualTapesGroup, enter a name, set a limit (have tried with and without a limit) and click apply. It thinks for a few minutes, then comes back. No error or anything, just refreshes the information and lists no tapes... as if I hadn't done anything.
I followed the instruction in this KB article to refresh the backup DB, but that didn't help.
After trying again, I noticed that the message displayed after attempting to create a new backup database is "New backup database created on selected share.", while the message displayed in the "critical_errors.log" file is "10:59:25 22-04-11 warning Creating backup database failed."
I tried deleting the share & LV, created a seperate (new) LV and even tried putting the DB on a regular share. None have worked so far. I still get the error in critical_errors.log and no tapes can be labeled.
Per Gr-R's helpful advice, there seemed to be filesystem corruption
Here's what needed to be done:
Disable Local Backup (Configuration -> NAS Settings -> disable Local Backup)
Delete the logical volume that contained the backup (any data on this LV WILL BE LOST!)
Fix the filesystem:
(From the console) Go to Extended Tools (Ctrl-Alt-X), Select "Repair filesystem on LV" (#9), Hit yes to continue, then REBOOT!
