Hi Friends,

Please note that, when replace-brick operation was tried for one of the bad brick present in distributed disperse EC volume, the command actually failed but the brick daemon of new replaced brick came online.
Please help to understand in what situations this issue may arise and proposed solution if possible ? :

Replace brick failure, brick [/ws/disk3], volume [AM6_HyperScale]

"gluster volume status" now shows a new disk active /ws/disk15

The replacement appears to be successful, looks like healing started
