We are using 2.4.9-31SGI_XFS_1.1 kernel release and we hadnt any problems
on any of our production machines since the release. Recently on some of
newer machines we hit some strange (XFS related?) problems. Processes that
try to access FS (like /bin/ls) block in D state indefinetly. This
processes exit when sent a TERM signal (no need for KILL). The only change
(other that hardware) from the older systems is that we now use external
log (maximum 128M size). After "some" time the machine stoped responding
at all (was responding on ping but not other services), but we lost any
"kernel panic" messages. That wont happen again :)
Because some time ago we hit a similar problem (2.4.10 xfs kernel with
DMAPI problem), and we used kdb to hunt down the problem we want now to
try the same thing.
Problem is I dont seem to find a proper kdb patch for 2.4.9-31SGI_XFS_1.1
kernel. Can somebody help me ?
