Great, I put things on xfs this weekend and all seems to be running fine.  Thanks for the info.

Aren't there concerns with xfs and large files in cases of failures?  I
was under the impression that if xfs was writing to a file and the
system died it would zero out the entire file.  Just hesitant to put
large vm files on a fs like that.  Is this still an issue with xfs?

There are no known problems with recent kernels. There are quite a few enterprise storage solutions that run on xfs.

Thanks,
Vijay

        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

          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>.  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?


    There are known problems with ext4 and gluster at the moment. Can
    you please confirm if you see similar behaviour with xfs and gluster?

    Thanks,
