Several times I've had my SMP machine with EVMS and XFS filesystems lock
up and need to be reset. After the reboot, sometimes filesystems won't
mount (it tends to be the "/var" partition) and I must boot to single
user mode.
When I attempt to mount the filesystem to cause the log replay, it
refuses to do so, giving an error about an "invalid client id". I must
then run "xfs_repair -L" on it to get the machine back online.
What does that error mean, and is there a way to make it mount anyway
and replay the log?
How can I debug system lockups like that, so that I can give a
meaningful and useful bug report? Will someone please work with me in
private mail (or direct me to the relevant mailing list or
documentation) and teach me how to debug the Linux kernel, to find
lockups and such?
