Hello all,
I've installed amanda-2.4.1p1 on a machine running Linux-2.2.16 to do the
backup on the Dell PowerVault 120T autochanger with 7 slots using DLT4000
tapes. This machine is used to back up some local filesystems as well as
filesystems from several other remote machines all running Solaris 8.
Occasionally the backups completed without problem, but more often at least
one (could go up to 3 out of 7) local filesystem failed with the [data timeout]
error, yes most peculiarly, all filesystems that failed are on the local
machine (which is also running amanda server). I have tried to increase
the READ_TIMEOUT value from the default 30mins to 60mins in server-src/dumper.c
but without any improvement.
Anytime a filesystem failed to backup, the tapedrive seemed to be idle forever
until the READ_TIMEOUT period lapsed, i.e no activity shown.
These are some typical error from the log:

I'm just wondering if anyone has come across this before and give me some
help to resolve this problem. Any help would be much appreciated.
TIA
