Hi again,
in today's gluster meeting [1] it has been decided that 3.7.1 will be
released urgently to solve a bug in glusterd. All fixes planned for
3.7.1 will be moved to 3.7.2 which will be released soon after.

Options Reconfigured:

We did some performance testing and simulated the proactive self
healing
for Erasure coding. Disperse volume has been created across
nodes.
_*Description of problem*_
I disconnected the *network of two nodes* and tried to write
some video
files and *glusterfs* *wrote the video files on balance 8 nodes
perfectly*. I tried to download the uploaded file and it was
downloaded
perfectly. Then i enabled the network of two nodes, the pro
active self
healing mechanism worked perfectly and wrote the unavailable
junk of
data to the recently enabled node from the other 8 nodes. But
when i
tried to download the same file node, it showed Input/Output
error. I
couldn't download the file. I think there is an issue in pro
active self
healing.
Also we tried the simulation with one node network failure. We
faced
same I/O error issue while downloading the file
_Error while downloading file _

We can't conclude the issue with glusterfs 3.7.0 or our glusterfs
configuration.
Any help would be greatly appreciated
