It + will try to connect to an existing etcd cluster and grab a lock in that + cluster to function as CTDB's cluster lock. Please see + <emphasis>ctdb/doc/cluster_mutex_helper.txt</emphasis> for details on + the mutex helper API. To use this, include the following line in + the <literal>[cluster]</literal> section of + <citerefentry><refentrytitle>ctdb.conf</refentrytitle> + <manvolnum>5</manvolnum></citerefentry>: + </para> + <screen format="linespecific"> +cluster lock = !/usr/local/usr/libexec/ctdb/ctdb_etcd_lock + </screen> + <para> + You can also pass "-v", "-vv", or "-vvv" to include verbose output in + the CTDB log. Additional "v"s indicate increases in verbosity. + </para> + <para> + This mutex helper expects the system Python interpreter to have access + to the etcd Python module. It also expects an etcd cluster to be + configured and running. To integrate with this, there is an optional + config file of the following format: + </para> + <screen format="linespecific"> +key = value + </screen> + <para> + The following configuration parameters (and their defaults) are defined + for use by ctdb_etcd_lock: + </para> + <screen format="linespecific"> +port = 2379 # connecting port for the etcd cluster +lock_ttl = 9 # seconds for TTL +refresh = 2 # seconds between attempts to maintain lock +locks_dir = _ctdb # where to store CTDB locks in etcd + # The final etcd directory for any given lock looks like: + # /_locks/{locks_dir}/{netbios name}/ + </screen> + <para> + In addition, any keyword parameter that can be used to configure an + etcd client may be specified and modified here.
