Yeah, looks like it couldn't write to the log, so it marked the file 
system as down.  Believe it or not, this may have saved you ...

Do a

	umount -l /xfs/mount/point

and wait a bit.  It will do the umount in the background.  Put a 
"noauto" option on this in the /etc/fstab just in case  you need to reboot.

BTW:  Which kernel is this?  The stock Centos kernels xfs support comes 
from centosplus.  Support for xfs isn't bad, but in general, the 
RHEL/Centos kernels aren't (in our experience) stable against very heavy 
loads, nor are they terribly good with xfs.  5.5 is better.

Joe
