In my attempts to track down the pthreads problem related to EOT not being properly returned, I've installed a QIC tape into my Bacula (http://www.bacula.org/) development box: FreeBSD undef.example.org 5.1-CURRENT FreeBSD 5.1-CURRENT #1: Wed Sep 10 14:43:34 EDT 2003 dan@undef.example.org:/usr/obj/usr/src/sys/UNDEF i386 sa0 at ahc0 bus 0 target 2 lun 0 sa0: <WANGTEK 51000 SCSI M74H 12B3> Removable Sequential Access SCSI-CCS device sa0: 3.300MB/s transfers With a tape in the drive, I attempt a status: # mt -f /dev/sa0 status mt: /dev/sa0: Invalid argument This appears in /var/log/messages: Sep 14 11:59:23 undef kernel: (sa0:ahc0:0:2:0): unable to set fixed blocksize to 1024 Similar entries appear for rewind, offline, retension. Archive seaches lead me to believe the problem is related to the drive not knowing that the device needs a particular blocksize. But I can't set the blocksize using "mt blocksize" (it gives the error mentioned above). Ideas please?
