[Gluster-users] Problems repairing volume

[Curro Rodriguez]

Hello Kevin,

I think you can't rebalance because you are not using a distributed
gluster, you are using replicated gluster instead, I had a similar problem
some time ago, and It is supposed that gluster self-heal will sync the
replicas.

You can trigger the heal with:

gluster volume heal nmd full

Anyway after reading and googling a lot one member told me that we could
resync fast if you do

find -exec stat {} \;

on a mounted client. This solution wasn't the ideal but started to resync
faster than heal-self. Still slow 5MB/s but better than nothing.

I am starting with glusterfs too, but I am sure someone could help you
better than me.

Kind regards.

Curro Rodríguez.
