What does "quorum" means in the command vgchange

[James R. Ferguson · Accepted solution]

Hi:

"quorum" is simply the requirement for 51% or more of the disks in a volume group to be present in order for volume group activation.

when mirroring quorum is used to ensure that at least half the physical disks are not missing. if they are then the system will not be able to be activated.if this fails during run time a message will appear on the console

vgchange activates volume groups and quorum is checked when those are activated to make sure you have at least 1/2 those disks working.

hope this helps
