It is comparing a value in memory with the position on the tape, so there are other explanations. E.g. Bacula tried to rewind the tape but the hardware/OS refused. E.g. the hardware/OS returned 0 incorrectly when Bacula set the value in memory from the tape position in the past. It could also be a bug in Bacula. You could try running the bacula-sd with debug level 200, which might show more info about how the unexpected value was set. > If it would be helpful I could make my configs available without passwords > or client configs as well as the set up steps I put together when building > the server. > > Thanks again, > > James > > ---- > > Device { > Name = Drive-0 > Drive Index = 0 > Media Type = LTO4 > Archive Device = /dev/sa0 > Autoselect = yes #(default) > Automatic Mount = yes > AlwaysOpen = yes #(default) > RemovableMedia = yes #(default) > RandomAccess = no > Requires Mount = no #(default) > AutoChanger = yes > Hardware End of Medium = no #(not default, FFSF & !HEoM is common) > Fast Forward Space File = yes > BSF at EOM = yes #(not default, necessary) > Backward Space Record = no #(not default) > Backward Space File = no #(not default) > TWO EOF = yes #(not default) > Maximum File Size = 4GB #(def is 1GB but > reduces stops to write EOF) > Device Type = Tape > Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'" > Spool Directory = /spool > Maximum Spool Size = 3800G > Maximum Job Spool Size = 800G > } This looks OK, though you may not need the two eofs model. I use the following for an HP LTO1 drive on FreeBSD 8: Archive Device = /dev/nsa0 AutomaticMount = yes AlwaysOpen = yes Maximum Open Wait = 10 Offline On Unmount = no Hardware End of Medium = no BSF at EOM = no Backward Space Record = yes Backward Space File = yes Fast Forward Space File = yes TWO EOF = no Beware though that tapes written with different values of TWO EOF are not compatible with each other. __Martin > > > > > On 2011-07-07, at 9:21 AM, Martin Simmons wrote: > > >>>>>> On Thu, 7 Jul 2011 09:07:32 -0600, James Woodward said: > >> > >> Hello, > >> > >> Our older production servers are running FreeBSD 7.2 and Bacula 3.0.2. > >> > >> This particular server with the this issue is running FreeBSD 8.1 and > >> Bacula > >> 5.0.3 installed from the packages. > > > > OK, so it could be an OS bug too. > > > > Using /dev/sa2 on FreeBSD is not advisable -- can you try it with /dev/nsa2 > > instead? > > > > What is the Device config for this drive in bacula-sd.conf?
