Hello,
One of our
filesystems is failing to get backed up and I am interested in trying to
ascertain why. The report entry is:
compaqdev2 /export/home lev 0
FAILED [data timeout]
In the amdump file I
see the following suspicious entries. I get a series of "driver-idle:
no-diskspace" entries which span 3 hours:
driver: state time
1737.214 free kps: 254081 space: 2164824 taper: idle idle-dumpers: 1 qlen tapeq:
0 runq: 26 roomq: 0 wakeup: 15 driver-idle: no-diskspace
driver: state time
12480.205 free kps: 286720 space: 15482922 taper: writing idle-dumpers: 5 qlen
tapeq: 6 runq: 2 roomq: 0 wakeup: 86400 driver-idle:
no-diskspace
Then the filesystem
dump fails over an hour later:
driver: result time
17127.984 from dumper0: FAILED 01-00054 [data timeout]
I suspect that the
holding_disk may be running out of space and indeed amplot confirms this.
Does the "no-diskspace" refer to the holding_disk?
Why does the data
timeout occur over an hour after disk space becomes available? The
dtimeout parameter in amanda.conf is set to 1800.
I am using server side fast compression for this
filesystem. Assuming that the holding_disk space is to blame, what options
do I have to resolve this problem other than increasing the size of the
holding_disk?
The amdump file is
hard to interpret. Is there any documentation describing its
layout?
Thanks for your
help.
Yours,
Paul Duncan
