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?<br>

I have been trying for a month or so to get a 2 node cluster up and<br>
running. I have engine installed on the first node, then add each each<br>
system as a host to a posix dc. Both boxes have 4 data disks. After<br>
adding the hosts I create a distributed replicate volume using 3 disk<br>
from each host with ext4 filesystems. I click the 'optimize for virt'<br>
option on the volume. There is a message in events that says that it<br>
can't set a volume option, then it sets 2 volume options. Checking the<br>
options tab I see that it added the gid/uid options. I was unable to<br>
find in the logs what option was not set, I just see a message about<br>
usage for volume set <volname> <option>. The volume starts fine and I<br>
am able to create a data domain on the volume. Once the domain is<br>
created I try to create a vm and it fails creating the disk. Error<br>
messages are along the lines of task file exists and can't remove task<br>
files. There are directories under tasks and when trying to manually<br>
remove them I get the "directory not empty" error. Can someone please<br>
shed some light on what I am doing wrong to get this 2 node cluster with<br>
local disk as shared storage up and running?<br>

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