That is correct but that is a function(..or limitation..) of the local,
on-disk file system and not GlusterFS. In fact, if you use the replicate
translator you can have multiple copies of your data on different
machines so it is possible for you to stop relying on an fsck for data
availability.

That depends on how you configure it. What you say above, is valid
in case you use distribute or stripe translator but is not valid
if you use the replicate translator.

Not through GlusterFS.

Yes. When CIFS support comes in, it will be usable without requiring
Samba.
