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

[Strahil Nikolov]

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?

Thanks!
