Hi,
When I rm -rf a directory of a few hundred thousand
files/directories on XFS under 2.6.38.1, I see the following, is
this normal?
No. What is you filesystem config (xfs_info) and your mount options?
Is it repeatable? I? the system otherwise stalled or is it still
operating normally? Does it recover and work normally after such a
stall?
Hi Dave, default mkfs.xfs options:

Is it repeatable?
I've not tried to repeat it as is spews messages over all of my consoles but
it has happened more than once.

The console/xterm/ssh etc that is performing the removal does lockup but
you are able to access the machine via a separate ssh connection.
Does it recover and work normally after such a stall?
Yes, eventually, I believe I started seeing this problem when I added
'delaylog' option to the mount options..
Justin.
