Dear list,
i am using amanda to backup some filesystem on my server.
I am using amanda version 2.4.4p1 on a FreeBSD 4.8
I use tar to backup only parts of the tree, small enough to fit on a
single tape.
The tapes i use are DLT-IV tapes and the drive is an DLT-8000.
This should mean i can backup about 40G on a single tape. I am using
software compression and turned off hw compression on the drive.
But today it happend that even a dump with a compressed size of 33075
MB failed to dump because of a tape error [out of tape]
*** A TAPE ERROR OCCURRED: [[writing file: short write]].
And in my system log i found these lines :
Jan 7 19:47:37 stern /kernel: (sa0:ahc0:0:6:0): WRITE FILEMARKS. CDB:

Jan 7 19:47:37 stern /kernel: (sa0:ahc0:0:6:0): tape is now frozen-
use an OFFLINE, REWIND or MTEOM command to clear this state.
This happens quite often the last times when using amanda.
How can this happen. Is there something wrong in my thoughts ?
