I had a question on the expected behaviour of simple distributed volumes when a brick fails for the following scenarios (as in, will the scenario succeed for fail) :

- New file creation if that file name hashes to the failed brick

Fails
 
- New file creation if that file name hashes to one of the remaining functional brick

Succeeds

- New directory creation if that file name hashes to the failed brick

Fails
 
- New directory creation if that file name hashes to one of the remaining functional brick

Succeeds. Layout is spread only to the functional bricks. Non-functional bricks are not part of layout of the directory. In other words files of the directory won't be stored in non-functional bricks
 
- File modifications/deletions if that file name hashes to the failed brick

Fails
 
- File modifications/deletions if that file name hashes to one of the remaining functional brick

Succeeds
 
- Directory renames/deletions if that file name hashes to the failed brick

Fails
 
- Directory renames/deletions if that file name hashes to one of the remaining functional brick

Fails
