I have a test machine which has started locking up when I run my backup script.
The script creates a LVM snapshot for each of 3 LVs in turn and then uses
xfsdump to back them up.
After the lockup, nothing seems to work, but the keyboard lights are flashing.
I'm running a pure CVS kernel from Sept. 6.
My warn.log file has:
Oct 20 01:15:22 TruStore1000 kernel: XFS mounting filesystem lvm(58,4)
Oct 20 01:15:28 TruStore1000 kernel: lvm - lvm_map: ll_rw_blk write for

Oct 20 01:15:29 TruStore1000 kernel: XFS mounting filesystem lvm(58,3)
The filesystem config_snap has already been deleted.
I have not tried to reproduce this, but I suspect I can. It has happened twice
Is it likely a updated CVS kernel would fix this?
Is there more data I can provide?
