Backup Central

I'm having problems when I try to set amanda up to completely fill my
tapes. One of my disklist entries is about 600GB at level 0. I'm using
amanda 3.2.1 on a RHEL5 tapehost with Ultrium tapes that hold 200GB. I
set:
flush-threshold-dumped 100
flush-threshold-scheduled 100
taperflush 100
autoflush yes

When I watch amstatus, I see the big DLE tape tape up to 100%, but then
it reports a PARTIAL tape. Then all the other DLEs waiting to tape
report "process canceled waiting to be taped" and they stay on the
holding disk. The report states that 602GB were left on the holding
disk.

When I set the three variables to 0, taping proceeds normally, and the
big DLE and the rest of the DLEs span four tapes correctly. However,
most of the time, the tapes are only filled to less than 5%.

Any suggestions on what I can do to fill tapes to capacity? Thanks for
your help and suggestions.

No suggestion, just a clarification. No DLE is a candidate
to be taped, or is included in the flush-threshold-dumped
calculation UNTIL it is completely dumped to the holding disk.
So your 600GB DLE might dump 300% of a single tape capacity
before it will tape or be included in the threshold calc.

Kevin,

Post the amdump.? log file, I want to look at it.
