Technically speaking, yes - the size information is contained in omap attributes of header, but I`d recommend you to check this approach somewhere else. Even if this will work, this will leave a lot of stray files in filestore. If you are running VM on top of it with recent qemu, it`s easy to tell the emulator desired block geometry (size), then launch a drive-mirror job and occasionally change backing image (during power cycle for example). Although second one may work, I am not absolutely sure that drive-mirror job will respect geometry override, better to check this too. _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
