Re: [ceph-users] question on rbd resize
No, most filesystems can be expanded pretty trivially (shrinking is a more complex operation but usually also doable). Assuming the likely case of an ext2/3/4 filesystem, the command "resize2fs /dev/rbd0" should resize the FS to cover the available space in the block device.

You need to resize the filesystem within the RBD block device.
