Subject: [Bug 12815] JBD: barrier-based sync failed on dm-1:8 - disabling barriers  -- and then hang

------- Comment #1 from sandeen@...hat.com  2009-03-03 21:29 -------
ext4 has barriers on by default, so you'll see the disabling barriers message
on lvm every time you mount (it does not support barriers).

if you'd like to rule that out, mount with -o barrier=0

When you're hung, try echo w > /proc/sysrq-trigger (or SysRq-W) to get a list
of sleeping processes.
