The "export" image was the wrong size as compared to "rbd info [image]@[snap]"? What are you comparing the sha1sum against? > 2) rbd export > some_file creates a 512GB file and a correctly sized import and sha1sum, however the VM disk has some sort of corruption and the OS won't properly load. The sha1sum of the "some_file" matches or the sha1sum from re-exporting the newly imported image? > 3) rbd import with --sparse-size0 results in an incorrect sha1sum > _______________________________________________ > ceph-users mailing list -- ceph-users@xxxxxxx > To unsubscribe send an email to ceph-users-leave@xxxxxxx > -- Jason _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
