Hello,

additionally: if rank 0 is lost, the whole FS stands still (no new

my guess is that the root of a cephfs (/; which is always served by rank
0) is needed in order to do traversals/lookups of any directories on the
top-level (which then can be served by ranks 1-n).

Could someone confirm if this is actually how it works? Thanks.
