Could you share
(1) the output of 'getfattr -d -m . -e hex <path>' where <path> represents the path to the original file from the brick where it resides
(2)  the size of the file as seen from the mount point around the time when (1) is taken
(3) output of 'gluster volume info'

Subject: Shard file size (gluster 3.7.5)

Have upgraded my cluster to debian jessie, so able to natively test 3.7.5

 

I’ve noticed some peculiarities with reported file sizes on the gluster mount but I seem to recall this is a known issue with shards?

 

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?
