[Gluster-users] Gluster 5.10 rebalance stuck

[Diego Zuccato]

I think I've been in a similar situation.
"Solved" by creating a new volume on a new set of bricks on the same 
disks and moving data to new volume. Then just deleted old volume and 
relative bricks. Quite sure there's a better way, but that was 
nearly-static data and the move was a faster fix.
