Re: [Bacula-users] End of Tape errors with HP LTO-4 drive on Linux

Bacula works perfectly so far.
The only serious problem I have is End of Tape detection.
E.g. if I need to reboot the backup server, the current tape will be rewinded.
The next backup job then seems not to find the end of the last backup and the tape will be set to Error state:

14-Apr 04:00 bacula-sd JobId 925: Volume "Weekly1" previously written, moving to end of data.
14-Apr 04:23 bacula-sd JobId 925: Error: Unable to position to end of data on device "LTO-4" (/dev/nst0): ERR=dev.c:954 ioctl MTEOM error on "LTO-4" (/dev/nst0). ERR=Input/output error.
14-Apr 04:23 bacula-sd JobId 925: Marking Volume "Weekly1" in Error in Catalog.

I already tried playing with TWO EOF = yes/no with no luck.

Any ideas?

Robert,
did you solve this? What tape / library are you using? We are just about to start using a number of LTO4 drives,so this will be something we'd want to test.

btw, what happens if you rewind the tape manually? (ie, unmount @ bacula, mt -f /dev/nst0 rewind && mtx -f /dev/xxx unload x, then load in bacula again.

Is bacula writing while the reboot happens?

cheers,
B
