hello,
i try to get a setup working, where i shut down 2 of 3 nodes,
and ceph should keep still working, e.g. like a raid 1 + spare.
setup is done under precise 12.04 latest patchlevel, ceph version is 0.56.2,
every node acts als mon, mds an osd, using default pools.
i tried different variants, changing replication level (rep size) for
all (default) pools
(data, metadata, rbd) from 2 to 3, min_size to 0 (i know this isnt a
good idea,
just a proof of concept)
but the result is always the same:
if i shut down the first node, everything keeps working,
but after shutdown of the second node, ceph stops working, mount is
unreachable.
any ideas?
thanks in advance
oliver
