9 ctdb_mutex_ceph_rados_helper can be used as a cluster lock provider for
10 CTDB. When configured, split brain avoidance during CTDB recovery will
11 be handled using locks against an object located in a Ceph RADOS pool.
12 To enable this functionality, include the following line in the
13 [cluster] section of ctdb.conf(5):
14
15 cluster 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 cluster lock holder in Ceph Manager's service map.
