NAME

6       ctdb_mutex_ceph_rados_helper - Ceph RADOS cluster mutex helper
7

DESCRIPTION

9       ctdb_mutex_ceph_rados_helper can be used as a recovery lock provider
10       for CTDB. When configured, split brain avoidance during CTDB recovery
11       will be handled using locks against an object located in a Ceph RADOS
12       pool. To enable this functionality, include the following line in the
13       [cluster] section of ctdb.conf(5):
14
15           recovery lock = !ctdb_mutex_ceph_rados_helper [Cluster] [User] [Pool] [Object]
16
17           Cluster: Ceph cluster name (e.g. ceph)
18           User: Ceph cluster user name (e.g. client.admin)
19           Pool: Ceph RADOS pool name
20           Object: Ceph RADOS object name
21
22
23       The Ceph cluster Cluster must be up and running, with a configuration,
24       and keyring file for User located in a librados default search path
25       (e.g. /etc/ceph/).  Pool must already exist.
26
27       For informational purposes, ctdb_mutex_ceph_rados_helper will also
28       register the recovery lock holder in Ceph Manager's service map.
