I am trying to backup data from a distributed replicated volume.

The volume was built from 6 units of 2 TB hard disks:

gluster> volume info

Volume Name: 6TB-Vol
Type: Distributed-Replicate
Status: Started
Number of Bricks: 3 x 2 = 6
Transport-type: tcp
Brick1: c107:/exp0
Brick2: c108:/exp0
Brick3: c109:/exp0
Brick4: c110:/exp0
Brick5: c111:/exp0
Brick6: c112:/exp0
Options Reconfigured:

c109: /dev/sdd1     ext2    1.8T  1.2T  533G  70% /exp0
c110: /dev/sdd1     ext2    1.8T  1.2T  533G  70% /exp0
c111: /dev/sdd1     ext2    1.8T  1.3T  495G  72% /exp0
c112: /dev/sdd1     ext2    1.8T  1.3T  495G  72% /exp0

When I backup the data to another storage, cp command hangs with "Invalid argument" errors.

I also tried this command: find <mount-point> -print0 | xargs --null stat >/dev/null and it didnt help.

I really need to get the data from  this volume. Please help!!!
