Hi,

Does anyone now why Amanda might generate an out of tape error in a
situation where it blatantly isn't anywhere even close to the end of the
tape?

I'm dumping four servers to an external Ultrium 100/200Gb unit, with
hardware compression turned off, and the largest filesystem failed last
night. Selected excerpts from the log:-

======================================================================
*** A TAPE ERROR OCCURRED: [[writing filemark: 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: ACU-STD-15.

FAILURE AND STRANGE DUMP SUMMARY:
  castor     sda12 lev 1 STRANGE
  castor     sda8 lev 0 STRANGE
  castor     sda10 lev 0 FAILED [out of tape]

======================================================================

the filesystem in question:-

======================================================================
                             DUMPER STATS                  TAPER STATS
HOSTNAME  DISK  L  ORIG-KB   OUT-KB  COMP%  MMM:SS   KB/s  MMM:SS KB/s
----------------- ---------------------------------------  -------------
castor   sda10  0  36167772  20726828 57.3  188:08 1836.2  FAILED ------
======================================================================

and the notes:-

======================================================================
NOTES:
 planner: Incremental of pollux:sda8 bumped to level 2.

 taper: tape ACU-STD-14 kb 9456384 fm 29 writing filemark: Input/output
error
 driver: going into degraded mode because of tape error.
======================================================================

The tapetype entry was generated for this drive by running amtapetype,
and is:-

define tapetype HP-ULTRIUM-230 {
    comment "HP Ultrium 230e"
    length 101376 mbytes
    filemark 0 kbytes
    speed 13855 kps
}

I've had successful runs with more data than this one would have had -
is this just a glitch, or is there something I can/should be doing about it?

Mike.
