Hi,

Many months of happy activity and then suddenly, last two nights, the
AMANDA job has failed to finish properly - the error in the AMANDA
report says:

These dumps were to tape Daily-014.
*** A TAPE ERROR OCCURRED: [[writing file: Input/output error]].
Some dumps may have been left in the holding disk.
Run amflush to flush them to tape.
The next tape Amanda expects to use is: Daily-015.

I notice it mentions "out of tape" above - that's definitely wrong.
There's certainly plenty of room for all the dumps.

And in the kernel logs for the AMANDA server:

What looks like the problem here?  The drive itself?  The SCSI
controller?  We have a HP DLT-40 drive on an Adaptec 29160 controller.
There have been no configuration changes to the server.
