Re: posix_handle_hard [file exists]

These log messages represent a transient state and are harmless and can be ignored. This happens when a lookup and mknod to create shards happen in parallel.

Regarding the preallocated disk creation issue, could you check if there are any errors/warnings in the fuse mount logs (these are named as the hyphenated mountpoint name followed by a ".log" and are found under /var/log/glusterfs).

    Hi,
    I have the similar issues with ovirt 4.2 on a glusterfs-3.8.15
      cluster. This was a new volume and I created first a thin
      provisioned disk, then I tried to create a preallocated disk but
      it hangs after 4MB. The only issue I can find in the logs sofar
      are the [File exists] errors with the sharding.
