[Dump-devel] Weird problems with latest dump and exabyte

[Denis G. <de...@da...>]

Folks,
I have upgraded from 0.4b4 to 0.4b13 and now I have a weird write error. I
use exabyte 8505XL drives (tried with two of them). The error:
  DUMP: write error 2620 blocks into volume 1
  DUMP: Do you want to restart?: ("yes" or "no") 

It repeats on different drives (all the same model), different tapes,
local (redhat 6.0 kernel 2.2.6) or remote (from mandrake 6.0 kernel 2.2.14
to redhat 6.0 kernel 2.2.6). The block number is always the same - 2620.

So I dug into the code and found out that a slave is getting a write
error. So I compiled dump with -DWRITEDEBUG, and added errno output to the
relevant printf, and I got:
.... (a lot of output snipped)
slave 2 wrote 10240
slave 0 wrote 10240
slave 1 wrote 10240
  DUMP: write: Input/output error
slave 2 wrote -1
slave 2 only wrote 0 out of 10240 bytes and gave up. errno=5, Input/output
error
  DUMP: write error 2620 blocks into volume 1, signal=10
  DUMP: Do you want to restart?: ("yes" or "no") no

At this point I am stuck (or too tired to think about this anymore).
Any suggestions?
