1. Filesystems, Disks and Memory
Having first encountered LVM in HP-UX and now experimenting with it in Redhat and Gentoo, I am wondering, when is it actually good practice to use LVM? Obviously LVM doesn't work for boot partitions, so that question is a pretty easy answer: Not for /boot in Linux.
While trying to figure out... (1 Reply)

Sorry for the noob question; my experience is with Solaris.
Am I reading this right? Are these disks completely unused? Not possibly raw disks for informix or something?

VOTEQUORUM_OVERVIEW(8) Corosync Cluster Engine Programmer's Manual VOTEQUORUM_OVERVIEW(8)
NAME
votequorum_overview - Votequorum Library Overview
OVERVIEW
The votequuorum library is delivered with the corosync project. It is the external interface to the vote-based quorum service. This service
is optionally loaded into all ndes in a corosync cluster to avoid split-brain situations. It does this by having a number of votes assigned
to each system in the cluster and ensuring that only when a majority of the votes are present, cluster operations are allowed to proceed.
The library provides a mechanism to:
* Query the quorum status
* Get a list of nodes known to the quorum service
* Receive notifications of quorum state changes
* Change the number of votes assigned to a node
* Change the number of expected votes for a cluster to be quorate
* Connect an additional quorum device to allow small clusters to remain quorate during node outages.
votequorum reads its configuration from the objdb. The following keys are read when it starts up:
* quorum.expected_votes
* quorum.votes
* quorum.quorumdev_poll
* quorum.disallowed
* quorum.two_node
Most of those values can be changed while corosync is running with the following exceptions: quorum.disallowed cannot be changed, and
two_node cannot be set on-the-fly, though it can be cleared. ie you can start with two nodes in the cluster and add a third without reboot-
ing all the nodes.
BUGS
This software is not yet production, so there may still be some bugs.
