For reads, only the object extent needs to be reverse mapped:
|
|
|
|
$ rbd create --size 5M img
|
|
$ DEV=$(sudo rbd map img)
|
|
$ xfs_io -c 'pwrite 0 5M' $DEV >/dev/null
|
|
$ sudo rbd unmap $DEV
|
|
$ rbd snap create --no-progress img@snap
|
|
$ rbd snap protect img@snap
|
|
$ rbd clone img@snap cloneimg
|
|
$ rbd resize --no-progress --size 12M cloneimg
|
|
$ DEV=$(sudo rbd map cloneimg)
|
|
$ hexdump $DEV

For writes, the entire object needs to be reverse mapped:
|
|
|
|
$ rbd create --size 2M img
|
|
$ DEV=$(sudo rbd map img)
|
|
$ xfs_io -c 'pwrite 0 1M' $DEV >/dev/null
|
|
$ sudo rbd unmap $DEV
|
|
$ rbd snap create --no-progress img@snap
|
|
$ rbd snap protect img@snap
|
|
$ rbd clone img@snap cloneimg
|
|
$ rbd resize --no-progress --size 8M cloneimg
|
|
$ DEV=$(sudo rbd map cloneimg)
|
|
$ xfs_io -c 'pwrite -S 0xef 3M 1M' $DEV >/dev/null
