Gluster users - Jan 2017 - Strange problems with my Gluster Cluster

Hello,

I have a 32-nodes cluster each node has 2 brick of 1 TB each and I
configured only one distributed volume using all my 64 bricks

I suppose to have 64 TB of disk online but I can see only 36 TB!!

All bricks are online 

but the result of a volume status says that

an operation of rebalance failed.

In glusterd.vol.log I can see 

glusterd_volume_rebalance_use_rsp_dict] 0-glusterd: failed to get index"
repeated 32 times between [2017-01-14 17:04:18.727159] and [2017-01-14
17:04:23.796719]

Can anyone help me with this problem?

My glusterfs version is 3.7.8

 

Thank you in advance

Fedele Stabile
