fence_xvmd

NAME

SYNOPSIS

DESCRIPTION

If the virtual machines are backed by clustered storage or the virtual machines may be migrated to other physical machines, all physical machines in question must also be a part of their own CMAN/OpenAIS based cluster. Furthermore, the bare metal cluster is required to have fencing configured if virtual machine recovery is expected to be automatic.

fence_xvmd accepts options on the command line and from cluster.conf

OPTIONS

-f

Foreground mode (do not fork)

-d

Enable debugging output. The more times you specify this parameter, the more debugging output you will receive.

-i family

IP family to use (auto, ipv4, or ipv6; default = auto)

-a address

Multicast address to listen on (default=225.0.0.12 for ipv4, ff02::3:1 for ipv6)

-p port

Port to use (default=1229)

-I interface

Network interface to listen on, e.g. eth0.

-C auth

Authentication type (none, sha1, sha256, sha512; default=sha256). This controls the authentication mechanism used to authenticate clients. The three SHA hashes use a key which must be shared between both the virtual machines and the host machine or cluster. The three SHA authentication mechanisms use a simple bidirectional challenge-response based on pseudo- random number generation and a shared private key.

-c hash

Packet hash type (none, sha1, sha256, sha512; default=sha256). This controls the hashing mechanism used to authenticate fencing requests. The three SHA hashes use a key which must be shared between both the virtual machines and the host machine or cluster.

-k key_file

Use the specified key file for packet hashing / SHA authentication. When both the hash type and the authentication type are set to "none", this parameter is ignored.

-u

Fence by UUID instead of virtual machine name.

-?

Print out a help message describing available options, then exit.

-h

Print out a help message describing available options, then exit.

-X

Do not connect to CCS for configuration; only use command line parameters. CCS configuration parameters override command line parameters (because they are cluster-wide), so if you need to override a configuration option contained in CCS, you must specify this parameter.

-L

Local-only / non-cluster mode. When used with -X, this this option prevents fence_xvmd from operating as a clustered service, obviating the need to configure/run CMAN on the host domain.

-U uri

Force use of the specified URI for connecting to the hypervisor.

-V

Print out a version message, then exit.
