Hi

what does the /var/log/messages (or /var/adm/messages whichever) say around this time? You could have dirty heads, bad tapes or indeed a broken drive. Or something like a bad SCSI cable.
As I was trying to say, there is nothing even remotely related to this problem in the system log. Also, I'm nearly 100% sure that the error is somehow linked to specific images, not the actual tapes or the tape unit as such.

Note that I've now gone back to amanda-2.4.4, and successfully flushed some images that caused trouble in the past. I think an important question here is whether something related to the holding disk handling or taping of images has changed since 2.4.4.

I've been getting a lot of

*** A TAPE ERROR OCCURRED: [[writing file: I/O error]].

lately. This does not, however, happen all the time, and not for specific tapes, either. Also, I can't find any error messages related to the tape device in the system log etc., and I've tested the unit quite a bit, and based on that, I don't think the problem is really the *write*, but is rather related to the holding disk image read. I can't figure out how exactly, though.

How do I go about finding out what exactly is wrong? Also, who wrote the above mentioned error message? I'm a bit annoyed with that person now, I must say. Why? Well, for leaving out the file name from a file related error message, of course. [ Some serious flaming omitted at this point... ]

Amanda version
(brought to you by Amanda version 2.4.4p1)

Before that I used one of the 2.4.4 snapshots, and before that again, 2.4.4. I got the same problem with the snapshot release, but not 2.4.4 itself, I believe (so perhaps I'll downgrade...)
