Hello,
I recently update 2 servers (Scientific Linux 6) with a replicate volume
from gluster 3.4 to 3.5.0-2.
The volume was previously used to host qemu/kvm VM images accessed via a
fuse-mounted mount-point.
Now I would like to use the libgfapi but I'm seeing this error:
[root@cmsrm-service02 ~]# qemu-img info
gluster://cmsrm-service02/vol1/vms/disks/cmsrm-ui01.raw2

one of them comes back up.

This is a benign error message. qemu-img initializes a glusterfs graph
through libgfapi, performs the operation and then cleans up the graph.
afr translator in glusterfs displays this log message as part of a graph
cleanup operation. IIRC, qemu displays all log messages on stderr by
default and hence this message is seen.
The error message does not appear if I access the file via the mount-point.
There should be no functional problem even if this message is seen.
