I was finally able to pass the estimate timeout problem I was having
(solution: a combination of decreased cpu/swap intensive processes and
increased etimeout value). However, a couple of troubles came up:
I got failed dumps (I was expecting this) because of end-of-tape:
======================================================================
These dumps were to tape ISR005.
*** A TAPE ERROR OCCURRED: [[writing file: No space left on device]].
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: ISR001.

======================================================================
Now, I have a bunch of questions about this report:
1. what's the meaning of "Some dumps may have been left in the holding
disk."? I mean, can I expect them to be dumped on the next amdump? Or
do I have to call amcleanup/amflush (which?) to check them out to
tape? In this latter case, I'll be overwriting a tape of my cycle. I
have one spare tape (my cycle is 4 tapes, and I have a magazine of 5
loaded).
2. what does it mean to go "into degraded mode"?
3. let's take omni:/home/ag for instance; in NOTES amanda says "Last
full dump of omni:/home/ag on tape ISR005 overwritten on this run",
but in DUMP SUMMARY it says
DUMPER STATS TAPER STATS
HOSTNAME DISK L ORIG-KB OUT-KB COMP% MMM:SS KB/s MMM:SS KB/s
-------------------------- --------------------------------- ------------
omni /home/ag 1 11510 2649 23.0 0:45 58.5 0:05 576.7
meaning it was level 1. My interpretation is: since the last full dump
was overwritten, and the current one is level 1, I LOST the backup. Is
this correct? (Shall I panic?)
4. How can I figure out the *current* *state* of the whole backup
system? I'd like to know what full backups exist in what tapes, and
what levels and where, and whether I am able to recover everything
from the current tape set. The amanda mail report are great, but they
only reflect the last amdump operation. I'd like to know about the
actual state of the whole tape set.
5. I read somewhere in amanda docs that whenever there is a
end-of-tape, the next one is automatically loaded and overwritten with
the dumps that did not fit on the previous one. Is this true? However,
in this amanda report I quoted, "These dumps were to tape ISR005" and
"The next tape Amanda expects to use is: ISR001" which seems ok (I
only have ISR001-ISR005). So can I conclude that amanda *only* used
one tape? The dumps that did not fit are on holding disk?
Thank you,
Cheers,
Rodrigo Ventura
