Topic: Tape backup problem

[David White]

Dear All

I am using v5.5 on a Compaq server equiped with a SCSI tape drive.  Below is my tape backup log.  Can anyone explain why the backup appears not to be working?  What does "Can't read next inode while scanning inode #56896" mean?  I have tried a couple of different tapes and have cleaned the tape heads etc.

Thanks in advance

Dave

I would say there's a problem with your hard disk rather than your tape drive. It looks like there's a file / file structure corruption.

Unfortunately, I'm not an expert with fsck as you will likely need to use that to try and fix the problem. Could be a sign of a failing hdd too.

Thanks Kelvin,

I'll try and figure out out to fsck it.
