[Gluster-users] Recovering from remove-brick where shards did not rebalance

The data should be recoverable by concatenating the main file with all shards. Then you can copy the data back via the FUSE mount point.
I think that some users reported that add-brick with the force option allows to 'undo' the situation and 're-add' the data, but I have never tried that and I cannot guarantee that it will even work.
The simplest way is to recover from a recent backup , but sometimes this leads to a data loss.

I did a bad thing and did a remove-brick on a set of bricks in a distributed-replicate volume where rebalancing did not successfully rebalance all files. In sleuthing around the various bricks on the 3 node pool, it appears that a number of the files within the volume may have been stored as shards. With that, I'm unsure how to proceed with recovery.
Is it possible to re-add the removed bricks somehow and then do a heal? Or is there a way to recover data from shards somehow?
