Hi,
I'm still confused with those error messages occuring when i dump to tape
with the Exabyte 17D streamer.
I dont think this is an Amanda problem since i get the same problem when
dumping with tar (when trying to flush the holding disk on tape myself) :
20010621/
20010621/dbstat._var.1
20010621/onew2._var_lib_news.1
20010621/obdba1._var.1
tar: /dev/nst0: Cannot write: Input/output error
tar: Error is not recoverable: exiting now
We tried to use a terminator, to change the cable, to change the streamer and
to change the tapes (we never got new tapes, but i tried to erase the ones i
had before backing up).
I didnt see anything in the Amanda lists, just a problem with the files
larger than 2Gb but as you can see in my amanda.conf, i limited the chunksize
to less than 2Gb (and it seems that 1Gb is the default). I tried to describe
my problem to the Amanda list, but i didn't get any answer.
The crash described in the logs at the end of this mail occurs after an
undefined backup size, between 800 Mb and 35 Gb (till now).
If you need any other info, please contact me.
Any help would be greatly apreciated.
We user amanda 2.4.1p1 on Debian Linux.
Here are my config files, logs, ... :

# dumptypes
#
# These are referred to by the disklist file. The dumptype specifies
# certain "options" for dumping including:
# index - keep an index of the files backed up
# compress-fast - (default) compress on the client using fast
algorithm
# compress-best - compress using the best (and slowww) algorithm
# no-compress - don't compress the dump output
# srvcompress - Compress dumps on the tape host instead of client
# machines. This may be useful when a fast tape host
# is backing up slow clients.
# record - (default) record the dump in /etc/dumpdates
# no-record - don't record the dump, for testing
# no-hold - don't go to the holding disk, good for dumping
# the holding disk partition itself.
# skip-full - Skip the disk when a level 0 is due, to allow
# full backups outside Amanda, eg when the machine
# is in single-user mode.
# skip-incr - Skip the disk when the level 0 is NOT due. This
# is used in archive configurations, where only full
# dumps are done and the tapes saved.
# no-full - Do a level 1 every night. This can be used, for
# example, for small root filesystems that only change
# slightly relative to a site-wide prototype. Amanda
# then backs up just the changes.
#
# Also, the dumptype specifies the priority level, where "low", "medium" and
# "high" are the allowed levels. These are only really used when Amanda has
# no tape to write to because of some error. In that "degraded mode", as
# many incrementals as will fit on the holding disk are done, higher priority
# first, to insure the important disks are dumped first.
