[Gluster-users] KVM guest I/O errors with xfs backed gluster volumes

[Jacob Yundt]

I'm still getting the same errors with 3.4.0beta4.  I increased the
brick log level to TRACE and repeated my same tests.  I keep getting
these errors:

I've updated the BZ
(https://bugzilla.redhat.com/show_bug.cgi?id=958781) with the full
glusterfsd logs, client logs and strace output.
