LVM - Quorum
Hi all
Just a question about quorum.
I am running AIX 5.3
Rootvg has 2 PV - not mirrored. quorum is switched on.

Thank you in advance

Hi all,
I would like to ensure that a volume group has an effective quorum setting of 1 (or off). I know you can change the quorum setting using the chvg -Q command but want to know if the setting has been changed before the vg was varied on or a reboot.
In other words how can I ensure that... (3 Replies)

votequorum_qdisk_register
VOTEQUORUM_QDISK_REGISTER(3) Corosync Cluster Engine Programmer's Manual VOTEQUORUM_QDISK_REGISTER(3)
NAME
votequorum_qdisk_register - Registers a new quorum device
SYNOPSIS
#include <corosync/votequorum.h>
int votequorum_qdisk_register(votequorum_handle_t handle, char * name, unsigned int votes);
DESCRIPTION
The votequorum_qdisk_register is used to register a new quorum device. A quorum device is an external way of adding votes to a small clus-
ter. The quorum device is, in effect, a pseudo node in the cluster that provide votes based on some external device, usually a shared disk
partition or perhaps a network router.
This call creates the device but does not mark it active. votequorum_qdisk_poll must be called for the votes to be included in the quorum
calculation.
Note that it is the responsibility of the quorum device subsystem (not provided as part of votequorum) to keep all nodes informed of the
quorum device status.
RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned.
ERRORS
The errors are undocumented.
