We're running a mix of ext3 and xfs file systems on CentOS 4
workstations at our site. We have benefitted greatly from the increased
performance and fast (crash recovery) reboot times that we get from
xfs. We're currently running CentOS kernel 2.6.9-42.0.8.EL and xfs
version 0.2-1.
We have one host where we've got issues. It's a (very) busy imap server
with external scsi hardware raid, dual Xeon CPUs, and 8GB of RAM (it
runs the hugemem kernel). Twice now in the last few weeks we've seen it
hang with the follow log message repeated many times in the logs at the
time of the hang:
XFS: possible memory allocation deadlock in kmem_alloc (mode:0x250)
I see this error discussed in:
http://oss.sgi.com/bugzilla/show_bug.cgi?id=410
...and I'm wondering if the fixes mentioned in that bug are present in
the 0.2-1 centosplus xfs drivers, or if it could get included in an xfs
update for CentOS 4. Can anyone comment?
Thanks for the filesystem, and the OS, it all rocks, and have a
great day.
