# Options to ctdbd. This is read by /etc/init.d/ctdb # you must specify the location of a shared lock file across all the # nodes. This must be on shared storage # there is no default CTDB_RECOVERY_LOCK=/usr/samba-ctdb/ctdb/share/storage # when doing IP takeover you also may specify what network interface # to use by default for the public addresses. Otherwise you must # specify an interface on each line of the public addresses file # there is no default # CTDB_PUBLIC_INTERFACE=eth0 # Should ctdb do IP takeover? If it should, then specify a file # containing the list of public IP addresses that ctdb will manage # Note that these IPs must be different from those in $NODES above # there is no default. # The syntax is one line per public address of the form : # / # Example: 10.1.1.1/24 eth0 # CTDB_PUBLIC_ADDRESSES=/etc/ctdb/public_addresses # Should CTDB present the cluster using a single public ip address to clients # and multiplex clients across all CONNECTED nodes ? # This is based on LVS # When this is enabled, the entire cluster will present one single ip address # which clients will connect to. # CTDB_LVS_PUBLIC_IP=10.1.1.1 # IPMUX : OBSOLETE use LVS instead # Should ctdb implement a single public ip address across the entire cluster # and multiplex incoming connections across the connected nodes # When using a single public ip you must also specify the public interface! # This makes all incoming traffic go through a single ctdb node which # will then forward the packets out acros the other nodes. This will # impact performance. # CTDB_SINGLE_PUBLIC_IP=10.1.1.1 # should ctdb manage starting/stopping the Samba service for you? # default is to not manage Samba CTDB_MANAGES_SAMBA=yes # should ctdb manage starting/stopping Winbind service? # if left comented out then it will be autodetected based on smb.conf # CTDB_MANAGES_WINBIND=yes # you may wish to raise the file descriptor limit for ctdb # use a ulimit command here. ctdb needs one file descriptor per # connected client (ie. one per connected client in Samba) # ulimit -n 10000 # the NODES file must be specified or ctdb won't start # it should contain a list of IPs that ctdb will use # it must be exactly the same on all cluster nodes # defaults to /etc/ctdb/nodes CTDB_NODES=/etc/ctdb/nodes # the directory to put the local ctdb database files in # defaults to /var/ctdb CTDB_DBDIR=/usr/samba-ctdb/ctdb/var # the directory to put the local persistent ctdb database files in # defaults to /var/ctdb/persistent CTDB_DBDIR_PERSISTENT=/usr/samba-ctdb/ctdb/persistent # the directory where service specific event scripts are stored # defaults to /etc/ctdb/events.d CTDB_EVENT_SCRIPT_DIR=/etc/ctdb/events.d # the location of the local ctdb socket # defaults to /tmp/ctdb.socket CTDB_SOCKET=/usr/samba-ctdb/ctdb/tmp/ctdb.socket # what transport to use.

Higher means more verbose # the default is 0 CTDB_DEBUGLEVEL=9 # set any default tuning options for ctdb # use CTDB_SET_XXXX=value where XXXX is the name of the tuning # variable # for example # CTDB_SET_TRAVERSETIMEOUT=60 # you can get a list of variables using "ctdb listvars" # any other options you might want.
