ccsd(8)ccsd(8)NAMEccsd - manages the /etc/cluster/cluster.conf file
SYNOPSISccsd [OPTION]..
DESCRIPTIONccsd is part of the Cluster Configuration System (CCS) and manages the
cluster.conf file in a cman cluster. It handles requests for clus‐
ter.conf information made through libccs. It also keeps the clus‐
ter.conf file in sync among cluster nodes based on the value of clus‐
ter.conf:cluster/config_version. ccsd may replace the local clus‐
ter.conf file if it discovers a newer version on another node.
OPTIONS-X Disable all cluster manager (cman) and inter-node interactions.
Simply respond to local libccs requests based on the current
cluster.conf file.
-4 Use IPv4 for inter-node communication. By default, IPv6 is
tried, then IPv4.
-6 Use IPv6 for inter-node communication. By default, IPv6 is
tried, then IPv4.
-I Force use of IP for local communication (disables use of UNIX
domain sockets). If set, ccsd will use the specified inter-node
communication protocol (see the -4 and -6 options). If one is
not specified, IPv6 is tried, then IPv4. For backward compati‐
bility, IP connections are still allowed even when UNIX domain
sockets are available.
-h Help. Print out the usage syntax.
-m <multicast address>
Used to specify the multicast address. The keyword "default"
can be used, in which case "ff02::3:1" is used for IPv6 and
"224.0.2.5" is used for IPv4.
If you are using IPv4, the default action is to use broadcast.
Specifying this option will cause multicast to be used in that
instance.
-n No daemon. Run in the foreground.
-P <port identifier>:<port number>
You have the option of specifying the port numbers used by ccsd.
The port identifier is either: b, c, or f. "b" is the port
which ccsd attempts to communicate with ccsd processes on other
machines, via broadcast/multicast, to obtain or validate its
config file (cluster.conf). This is known as the backend port.
"c" is the base port number of two consecutive ports used by
ccsd processes to communicate cluster membership information.
This is known as the cluster base port. "f" is the port number
that listens for information requests from the CCS library (or
programs using it). This is known as the frontend port.
So, to change the frontend port one might specify -P f:60000.
-t <ttl>
Set the multicast threshold (aka time to live).
-V Print the version information.
