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.

|
:command:`crc <prefix> <key>`
|
|
Get the CRC of the KV pair stored with the URL encoded prefix and key.

|
|
[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
