More concerningly, the files copied to the gluster shard datastores have a difference md5sum to the original. Thats a fatal flaw.

Source file is sparse, nominal size 64GB, real size 25GB. However underlying storage is ZFS with lz4 compression which reduces it to 16GB No Shard: ls –lh : 64 GB du –h : 25 GB 4MB Shard: ls –lh : 144 GB du –h : 21 MB 512MB Shard: ls –lh : 72 GB du –h : 765 MB a du –sh of the .shard directory show 16GB for all datastores Is this a known bug for sharding? Will it be repaired eventually? Sent from Mail for Windows 10
