After continued testing with other volumes they all read fine. I tried bacula again which was able to mount and read the volumes successfully. However, after a reboot, bacula reverted to it's previous state of not being able to read the tapes via either bls, or via the normal bacula-sd interaction.
This points me towards it being a host OS issue and settings that were lost after a reboot. I have no idea what though, I have checked my : mt -f /dev/nst0 stoptions and they are all as expected. Blocksize is set to variable mode and other options as per the troubleshooting guide. My question now is, what options can I tweak and how on the tape drive to try and get bls to work as it was before. If I get it working again, is there any way to check what those options are in place? All very confusing, considering this has worked in place for 3 years prior to upgrade. Thanks, Stephen. -----Original Message----- From: GILES Stephen Sent: 21 February 2013 12:22 To: bacula-users@lists.sourceforge.net Subject: Re: [Bacula-users] FW: difficulty reading tapes after upgrade 3.0.2 -> 5.2.12 I have tried the bls with the archive device.

You could try to find out exactly what the SD process has read from the tape, e.g. using "strace -f -s 1024 ..." or gdb breakpoints. You could add a file storage device with Archive Device = /tmp, dd the first block to a file in /tmp and then run "bls -d 200 /tmp/filename" to see what that says about the label (expect an error about "Wrong Volume mounted on device"). __Martin > > Stephen. > ________________________________________ > From: lst_ho...@kwsoft.de [lst_ho...@kwsoft.de] > Sent: 19 February 2013 14:55 > To: bacula-users@lists.sourceforge.net > Subject: Re: [Bacula-users] FW: difficulty reading tapes after upgrade > 3.0.2 -> 5.2.12 > > Zitat von GILES Stephen <stephen.gi...@ed.ac.uk>: > > > Hello, > > > > Is anyone able to suggest anything, or point me in a direction? > > Have I hit an unknown bug as I can't think what else to try. > > > > My bacula-sd.conf looks like this. > > > > Please see additional information below. > > > > ---------- > > Storage { # definition of myself > > Name = iota-sd > > SDPort = 9103 # Director's port > > WorkingDirectory = "/var/spool/bacula" > > Pid Directory = "/var/run" > > Maximum Concurrent Jobs = 20 > > } > > > > Director { > > Name = iota-dir > > Password = "###" > > } > > > > > > # NEO2000 tapedrive1 > > Device { > > Name = NeoLTO3-0 > > Drive Index = 0 > > Media Type = LTO3 > > Archive Device = /dev/nst0 > > Device Type = Tape > > > > AutoChanger = yes; > > AutomaticMount = yes; > > AutoSelect = yes; > > > > AlwaysOpen = no; > > RemovableMedia = yes; > > RandomAccess = no; > > Maximum Network Buffer Size = 262144 > > Maximum File Size = 10gb > > > > Minimum blocksize = 262144 > > Maximum blocksize = 262144 > > > > Spool Directory = /bacula-spool/1/ } > > > > # NEO2000 jukebox > > Autochanger { > > Name = NEO2000-1 > > Device = NeoLTO3-0 > > Changer Command = "/usr/libexec/bacula/mtx-changer %c %o %S %a %d" > > Changer Device = /dev/sg13 > > } > > > > Messages { > > Name = Standard > > director = iota-dir = all > > } > > > > > > > Hello > > The documentation for the on-tape-format is here: > > http://www.bacula.org/2.4.x-manuals/en/developers/Storage_Media_Output > _Format.html > > and at first glance old tape from version 3.x should be readable and > http://www.bacula.org/5.2.x-manuals/en/main/main/Bacula_Security_Issue > s.html#SECTION004310000000000000000 also suggest so. > > One thing to try is to only set the Maximum blocksize = 262144 and > leave the Minimum blocksize at the default (0) to prevent Bacula from > using *fixed* blocksize. > > Regards > > Andreas > > > > ---------------------------------------------------------------------- > -------- Everyone hates slow websites.
