Alternatives
1) nfs over rbd...

3) create a large Centos 6.4 VM (eg 15 TB, 1 TB for OS using EXT4,
remaining 14 TB using either EXT4 or XTRFS) on RBD and then install
NFS and SAMBA on it.
I can't see any holes in alternative #3 -- it's simple, reasonably
fast, and uses production stable technologies. (I can even control
quotas using normal LVM sizes.) Thoughts?
I'm looking at the same issue and (FWIW) have a similar idea to your
opt.3. My use case is essentially a bottom-less Windows share for large
files. My approach is to mount via iSCSI directly into a Windows guest
the maximum NTFS volume size (256TB) and rely on Server'12 TRIM being
passed through the stack to RBD to keep things thin
(http://ceph.com/docs/master/rbd/qemu-rbd/#enabling-discard-trim) - that
bit I need to test.
I'm not sure how stable NTFS is at that scale either.
