How about labeling all the tapes beforehand, before starting the job? Maybe you could then remove the first two tapes when they are full, while Bacula is writing the 3rd one, and put the new previously labeled tapes in. Maybe you could then also issue "update slots" command, and there would be no need to pause the job at all?
I don't know if this works, but I think it could be possible. "Update slots" does not need the drive itself but just scans the barcodes. Depending on the changer device you could be able to manipulate the contents of the tape library while the drive is working. And I believe Bacula also allows you to do this. If you cannot do it this way, at least it should be possible to change the prelabeled tapes when Bacula stops and asks new tapes when the tapes are in the catalog but not in the changer yet. So I think labeling the tapes in advance might be the solution here. -- TiN "Mike Hanby" <mha...@uab.edu> kirjoitti viestissä news:a72c1c64c331b445a593c79da1be580c265848b...@uabexmbs3.ad.uab.edu... > Thanks John, > > I hate when I think of all the details to provide in the email but forget > to type them out. > > Yes, it's a Dell PV-124T changer with a single LTO4 drive (also single > magazine, which with a 2nd mag, this wouldn't be an issue). > > I tried the auto-label during some testing and the I couldn't get to > produce the same label format that manually labeling produces via "label > barcodes". > > Mike > > -----Original Message----- > From: John Drescher [mailto:dresche...@gmail.com] > Sent: Friday, August 20, 2010 3:05 PM > To: Mike Hanby > Cc: bacula-users > Subject: Re: [Bacula-users] Swapping tapes mid job with an autochanger > >> If I have a multi LTO4 tape backup running that will require swapping >> tapes (i.e. it will use all of the tapes in the autochanger and require a >> few more), is there any way during the job for the operator to tell >> Bacula to pause once it finishes filling the current tape? >> >> The idea, I know I'm going to need to swap out / in two more tapes AND I >> know that the existing tapes won't fill up until 3 AM, why not let it >> finish writing the first 2 tapes, pause it, swap the first 2 tapes with >> new tapes, label them, mount the 3rd tape and let the job resume.
