Hello,
The following should be self-explanatory- it's a message going out
to users of TSM backup on Athena:
February 20, 2002
IMPORTANT NOTICE FOR LINUX TSM USERS
We have just become aware that that the current Linux TSM backup client is
not able to back up ext3 file systems- Linux-Athena has changed the
local file system from ext2 to ext3 as of Athena release 9.0.20, released
in January 2002.
THIS MEANS THAT TSM BACKUP (EITHER MANUAL OR SCHEDULED) ON
LINUX-ATHENA MACHINES WILL NOT WORK ON MACHINES RUNNING ATHENA 9.0.20
OR LATER.
Attempts to expand the local file system tree to back up files manually
with the dsm GUI will not reveal any files there, even though they may exist.
Scheduled TSM backups will silently fail without any obvious error messages
in the system log or error files.
A version of the Linux client that can handle ext3 file systems is
under development but we are not certain of the release date- the best
current estimate is around the end of March 2002. We'll install it as
soon as it becomes available.
Existing back-ups created when a machine had an ext2 file system
(pre-Athena 9.0.20) should still be recoverable, but only to a
machine running an ext2 file system.
In the meantime, if you maintain a private Linux-Athena machine that
has not updated to or beyond the 9.0.20 Athena release, and you want
to keep using the current version of the Athena TSM client, you can do
so provided that you set autoupdate to FALSE in /etc/athena/rc.conf
(which will prevent further Athena updates from happening
automatically). The Athena release you are running is given in the
last line of file /etc/athena/version.
