Brett, (Under Linux it's "stoptions" in place of "setstoptions".)
Under kernel 2.6 I have no results in /var/log/syslog or /var/log/messages Under kernel 2.4 I have this: Jul 14 11:30:32 localhost kernel: st0: Mode 0 options: buffer writes: 1, async writes: 1, read ahead: 1 Jul 14 11:30:32 localhost kernel: st0: can bsr: 0, two FMs: 0, fast mteom: 0, auto lock: 0, Jul 14 11:30:32 localhost kernel: st0: defs for wr: 0, no block limits: 0, partitions: 0, s2 log: 0 Jul 14 11:30:32 localhost kernel: st0: sysv: 0 nowait: 0 When I boot (under kernel 2.6) I noticed: Jul 14 15:36:49 localhost kernel: scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 7.0 Jul 14 15:36:49 localhost kernel: <Adaptec 2940 Ultra SCSI adapter> Jul 14 15:36:49 localhost kernel: aic7880: Ultra Wide Channel A, SCSI Id=7, 16/253 SCBs Jul 14 15:36:49 localhost kernel: Jul 14 15:36:49 localhost kernel: Vendor: SONY Model: SDX-500C Rev: 0204 Jul 14 15:36:49 localhost kernel: Type: Sequential-Access ANSI SCSI revision: 02 Jul 14 15:36:49 localhost kernel: target0:0:6: Beginning Domain Validation Jul 14 15:36:49 localhost kernel: target0:0:6: wide asynchronous.

So after the boot, I stop all the bacula daemons and I setblk 0 and stoptions 7 (buffer write + async writes + read ahead). Then I relaunch the bacula daemons. Is it possible that the kernel or the driver (or ...) "resets" the block size after a mt -f /dev/nst0 setblk 0 and an ejecting of the tape from the tape drive ? (I checked with mt -f /dev/nst0 status but it's still on '0' so I presume that the drive is still in variable block mode). Another question, is it possible that it fails because I don't *umount before ejecting the tape ? (I press on the eject button of the tape drive) In fact the people who have to change the tape when they received a mail should not access bconsole (too complicated ...), so all they have to do is to press on the button and put the other tape (so without having to *umount).
