I suspect that this has more to do with the new (IMO brain damaged) way 2.6 kernels deal with an attempt to open a drive that has no medium in it. Prior kernels opened the drive, and you could then query to see if a tape was mounted, new kernels simply hang for about 2 minutes waiting for something to be mounted, then return causing Bacula all kinds of pains until I finally worked out a reasonable solution (I think). Either endure it, or you can avoid it by making sure every drive has a volume mounted before starting Bacula, or you can update to the latest 1.39 beta, which hopefully does not have the problem. > > ... > foobar01-sd: dircmd.c:187 Message channel init completed. > > < delay > > > foobar01-sd: dircmd.c:194 <dird: statusfoobar01-sd: dev.c:382 open > dev: tape 6 opened > foobar01-sd: device.c:270 open dev "Drive-2" (/dev/nst1) OK > foobar01-sd: label.c:71 Enter read_volume_label res=0 > device="Drive-2" (/dev/nst1) vol=dev_Vol=*NULL* > foobar01-sd: dev.c:627 rewind res=0 fd=6 "Drive-2" (/dev/nst1) > > < delay > > > foobar01-sd: dev.c:653 Rewind error, No medium found. retrying... > foobar01-sd: dev.c:276 oepn dev: tape=1 dev_name="Drive-2" (/dev/ > nst1) vol=mode=OPEN_READ_ONLY > foobar01-sd: dev.c:323 open dev: device is tape > foobar01-sd: autochanger.c:267 Locking changer Overland2000 > foobar01-sd: autochanger.c:236 Run program=/etc/bacula/mtx-changer / > dev/sg4 loaded 0 /dev/nst1 1 > foobar01-sd: bpipe.c:292 Run program returning 0 > foobar01-sd: autochanger.c:238 run_prog: /etc/bacula/mtx-changer /dev/ > sg4 loaded 0 /dev/nst1 1 stat=0 result=0 > foobar01-sd: autochanger.c:276 Unlocking changer Overland2000 > foobar01-sd: dev.c:338 Try open "Drive-2" (/dev/nst1) > mode=OPEN_READ_ONLY nonblocking=2048 > foobar01-sd: dev.c:369 openmode=3 OPEN_READ_ONLY > > < delay > > > foobar01-sd: dev.c:382 open dev: tape 6 opened > > < delay > > > foobar01-sd: label.c:104 return VOL_NO_MEDIA: Couldn't rewind device > "Drive-2" (/dev/nst1): ERR=dev.c:678 Rewind error on "Drive-2" (/dev/ > nst1).
