Positional syntax:

ceph-objectstore-tool ... <object> (get|set)-bytes [file]
ceph-objectstore-tool ... <object> set-(attr|omap) <key> [file]
ceph-objectstore-tool ... <object> (get|rm)-(attr|omap) <key>
ceph-objectstore-tool ... <object> get-omaphdr
ceph-objectstore-tool ... <object> set-omaphdr [file]
ceph-objectstore-tool ... <object> list-attrs
ceph-objectstore-tool ... <object> list-omap
ceph-objectstore-tool ... <object> remove|removeall
ceph-objectstore-tool ... <object> dump
ceph-objectstore-tool ... <object> set-size
ceph-objectstore-tool ... <object> clear-data-digest
ceph-objectstore-tool ... <object> remove-clone-metadata <cloneid>
ceph-objectstore-tool ... <object> clear-snapset [(corrupt|seq|snaps|clones|clone_size|clone_overlap|size)]

<object> can be a JSON object description as displayed
by --op list.
<object> can be an object name which will be looked up in all
the OSD's PGs.
<object> can be the empty string ('') which with a provided pgid
specifies the pgmeta object

The optional [file] argument will read stdin or write stdout
if not specified or if '-' specified.

clear-snapset options:
  clear-snapset               : by default, clear clones, clone_size and clone_overlap
  clear-snapset corrupt       : clear entire snapset
  clear-snapset seq           : clear snapset.seq
  clear-snapset clone_size    : clear clone_size
  clear-snapset clone_overlap : clear clone_overlap
  clear-snapset clones        : clear clones
  clear-snapset snaps         : clear clone_snaps
  clear-snapset size          : break all clone sizes by adding 1
