Sindary, I didn't see a reply from anyone else your question so I'll
take a stab at it but I have very limited knowledge about this so don't
take it as doctrine.
A quorum device is a disk that is shared between clustered servers to
keep cluster configuration information current. I also think it is
dependent upon the servers & O/S as to how it is implemented and if the
quorum device can be used for user data or not.
>From Sun.
quorum device
A disk shared by two or more nodes that contributes votes used to
establish a quorum for the cluster to run. The cluster can operate only
when a quorum of votes is available. The quorum device is used when a
cluster becomes partitioned into separate sets of nodes to establish
which set of nodes constitutes the new cluster.
Cluster Members FAQ
Is the order in which nodes are booted significant?
In most cases, no. However, the boot order is important to prevent
amnesia (refer to Quorum and Quorum Devices for details on amnesia).
For example, if node two was the owner of the quorum device and node
one is down, and then you bring node two down, you must bring up node
two before bringing back node one. This prevents you from accidentally
bringing up a node with out of date cluster configuration information.
Take a look at this link for more in-depth information.
