Comment 3 Pranith Kumar K 2018-06-13 09:09:03 UTC 
On a gluster volume with 100GB if we try to create a gluster-block of size 100GB with pre-allocation, block creation succeeds but it silently fails to allocate the correct sizes for the shards on the posix xlator.

sh-4.2# du -sh .shard/* | awk '{print $1}' | sort | uniq -c
      1 18M
      1 26M
   1597 64M

Because of this when writes happen on a pre-allocated block device, writes fail with ENOSPC which shouldn't happen for preallocated files.
