Synopsis
|
|
========
|
|
|
|
| **ceph-monstore-tool** <store path> <cmd> [args|options]
|
|
|
|
|
|
Description
|
|
===========
|
|
|
|
:program:`ceph-monstore-tool` is similar to `ceph-kvstore-tool`. It allows
|
|
users to manipulate MonitorDBStore's data (monmap, osdmap, etc.) offline.
|
|
The default RocksDB debug level is `0`. This can be changed using `--debug`.
|
|
|
|
Please Note:
|
|
Ceph-specific options should be in the format `--option-name=VAL`
|
|
(specifically, do not forget the '='!!)
|
|
Command-specific options need to be passed after a `--`
|
|
e.g., `get monmap --debug -- --version 10 --out /tmp/foo`
|
|
|
|
