Hi, all; have had a running Amanda for years which (a) tried for a
full backup every night [dumpcycle 0], but (b) I often didn't put in a
tape, so I got incrementals on the holding disk instead. What I
wanted.
I just upgraded my server to FC4's stock 2.4.5, and now it won't go
into degraded mode for love nor money. Full dumps (with a tape in)
work as expected; other times, it just starts packing level-0 dumps
onto the holding disk until it runs out of space.
The changes to my amanda.conf (diffs below) seem innocuous; the
"reserve 100" seems to be seen (log says "reserving 8616884 out of
8616884 for degraded-mode dumps").
I _think_ it is correctly seeing that the tape isn't there...
driver: result time 120.963 from taper: TAPE-ERROR [tape_rdlabel: tape open:
/dev/nst0: Input/output error]
dump of driver schedule before start degraded mode:
--------
--------
dump of driver schedule after start degraded mode:
--------
--------
driver: state time 120.963 free kps: 2000 space: 8616884 taper: DOWN
idle-dumpers: 4 qlen tapeq: 0 runq: 0 roomq: 0 wakeup: 86400 driver-idle:
not-idle
... but I could be wrong.
Any ideas how to figure out what's changed (for the worse)? Thanks,
Will
