I can confirm that your ceph build now includes the commit
d55399ffec224206ea324e83bb8ead1e9ca1eddc Sage asked you to test, so
all should be good.

We try pretty hard not to break anything, so you should be able just
grab new releases, either as tarballs or via git (for git, run
something like "git fetch && git checkout v0.26"), build them, and
restart your cluster. However, Ceph is still going through rapid
changes, read the release notes carefully.

The server side needs ceph.deb.
For in-kernel client side, you need a fresh enough kernel, and
mount.ceph in ceph-client-tools makes it nicer to use.
For FUSE client side, you need libfuse.
librados is a client library for the object store, you don't seem to
be using it.
librbd is a client library for things like QEMU/KVM, you don't seem to
be using it.
I don't see any of our packages actually needing libcrush or libceph
(I guess that means they bundle the library in the binary directly),
so you shouldn't need those either (at least right now; some day we
may wish to wrestle the Automake monster and change that).
