I didn't understand if it can handle this use case: a file server with (simple case) a hot swappable SATA3 bay (or any other bus), N disks (N - 1 are offline.) Send files to the server (rsync, scp, anything), remove the disk and replace it with another one, iterate. NNCP should handle this so far. But would it be able to tell me on which disk a file is stored?
If this were handled at file system level, the FS should pretend all disks are online to let me list files and directories. When I want to access an offline file or mkdir or perform any write operation on offline disks, it would raise an error and tell me which disk to load into the server. Then I try again.
If NNCP doesn't do that, is there and Linux file system able to do it? I googled but I didn't find much.
