Subject: [Users] Issues using local storage for gluster shared volume
I have been trying for a month or so to get a 2 node cluster up and
running. I have engine installed on the first node, then add each
each system as a host to a posix dc. Both boxes have 4 data disks.
After adding the hosts I create a distributed replicate volume using
3 disk from each host with ext4 filesystems. I click the 'optimize
for virt' option on the volume. There is a message in events that
says that it can't set a volume option, then it sets 2 volume
options. Checking the options tab I see that it added the gid/uid
options. I was unable to find in the logs what option was not set, I
just see a message about usage for volume set <volname> <option>.
gid and uid options are enough to make a gluster volume ready for virt store. The third
option sets a group(called as virt group) of options on the volume mainly related to
performance tuning. To make this option work, you have to copy the file
https://github.com/gluster/glusterfs/blob/master/extras/group-virt.example to
/var/lib/glusterd/groups/ and name it as virt. Now you can click on 'Optimize for virt
store' again to set the virt group. Setting this group option recommended but not
necessary to make the gluster volume to be used as virt store.
I am not sure about the below errors, other people in the list can help you out.

The volume starts fine and I am able to create a data domain on the
volume. Once the domain is created I try to create a vm and it fails
creating the disk. Error messages are along the lines of task file
exists and can't remove task files. There are directories under
tasks and when trying to manually remove them I get the "directory
not empty" error. Can someone please shed some light on what I am
doing wrong to get this 2 node cluster with local disk as shared
storage up and running?
Thanks,
Tony
