Hello everyone, I have a 6 drive LTO4 Dell ML6000 changer, running on a Dell Poweredge 2900 with Suse Enterprise 10 SP2, and over the last weeks I've managed to get Bacula 3.0.2 running very well with it.
Except for one problem where every night now a few jobs stall requiring intervention requesting tapes. I am using brand new tapes that are being autolabelled and moved from a scratch pool. The autolabelling etc is all working well and I'm sure that's not causing problems. I've been trawling through the email archives, and found a few similar situations where people were using older versions of bacula that had a bug. But I thought that it was fixed in version 3.0.2...? Here's an excerpt from the storage status whilst the jobs are requiring intervention: Device "Drive-0" (/dev/tape/by-id/scsi-3500308c09f221090-nst) is mounted with: Volume: LX0005 Pool: Week3 Media type: LTO4 Slot 76 is loaded in drive 0.

I'll be adding what I can once it's running properly ;-) Thanks, Evan. (barkboy) This message and any attachments contain information that may be RMS Inc. confidential and/or privileged.
