[Gluster-devel] [POC] disaster recovery: reconstruct all shards

[Gandalf Corvotempesta]

Would be possible to add a command to use in case of disaster recovery
(where everything is broken) to recreate files from sharding ?

In example, let's assume a totally down cluster. no trusted pools and
so on but sysadmin knows which hdd is part of any distributed replica:

hdd1 + hdd2 + hdd3 are distributed and replicated to hdd4 + hdd5 + hdd6

a CLI could traverse hdd1,hdd2,hdd3 and reconstruct all shards
creating the original, unsharded file.
