+
+| **ceph-kvstore-tool** <leveldb|rocksdb|bluestore-kv> <store path> *command* [args...]
+
+
+Description
+===========
+
+:program:`ceph-kvstore-tool` is a kvstore manipulation tool. It allows users to manipule
+leveldb/rocksdb's data (like OSD's omap) offline.
+
+Commands
+========
+
+:program:`ceph-kvstore-tool` utility uses many commands for debugging purpose
+which are as follows:
+
+:command:`list [prefix]`
+    Print key of all KV pairs stored with the URL encoded prefix.
+
+:command:`list-crc [prefix]`
+    Print CRC of all KV pairs stored with the URL encoded prefix.
+
+:command:`exists <prefix> [key]`
+    Check if there is any KV pair stored with the URL encoded prefix. If key
+    is also specified, check for the key with the prefix instead.
+
+:command:`get <prefix> <key> [out <file>]`
+    Get the value of the KV pair stored with the URL encoded prefix and key.
+    If file is also specified, write the value to the file.
+
+:command:`crc <prefix> <key>`
+    Get the CRC of the KV pair stored with the URL encoded prefix and key. 
+
+:command:`get-size [<prefix> <key>]`
+    Get estimated store size or size of value specified by prefix and key.
+
+:command:`set <prefix> <key> [ver <N>|in <file>]`
+    Set the value of the KV pair stored with the URL encoded prefix and key. 
+    The value could be *version_t* or text.
+
+:command:`rm <prefix> <key>`
+    Remove the KV pair stored with the URL encoded prefix and key.
+
+:command:`rm-prefix <prefix>`
+    Remove all KV pairs stored with the URL encoded prefix.
+
+:command:`store-copy <path> [num-keys-per-tx]`
+    Copy all KV pairs to another directory specified by ``path``. 
+    [num-keys-per-tx] is the number of KV pairs copied for a transaction.
+
+:command:`store-crc <path>`
+    Store CRC of all KV pairs to a file specified by ``path``.
+
+:command:`compact`
+    Subcommand ``compact`` is used to compact all data of kvstore. It will open
+    the database, and trigger a database's compaction. After compaction, some 
+    disk space may be released.
+
+:command:`compact-prefix <prefix>`
+    Compact all entries specified by the URL encoded prefix. 
+   
+:command:`compact-range <prefix> <start> <end>`
+    Compact some entries specified by the URL encoded prefix and range.
