Write to first and last sectors and make sure we hit the right objects:
|
||||
|
||||
$ ceph osd pool create hugeimg 12 >/dev/null 2>&1
|
||||
$ rbd pool init hugeimg
|
||||
$ rbd create --size 4E --object-size 4K --image-feature layering hugeimg/img
|
||||
$ DEV=$(sudo rbd map hugeimg/img)
|
||||
$ xfs_io -c 'pwrite 0 512' $DEV >/dev/null # first sector
|
||||
$ xfs_io -c 'pwrite 4611686018427387392 512' $DEV >/dev/null # last sector
|

$ sudo rbd unmap $DEV
