Hi,
let me put it this way.
The concept and the usage pattern of an open-sharedroot cluster can be
described as follows (BTW we call the base technology the Diskless Shared
Root Cluster; http://en.wikipedia.org/wiki/Diskless_Shared_Root_Cluster):
1. Give one or more node concurrent access to a shared storage. That can
either be a cluster filesystem like GFS/OCFS2/GFS2(not yet) on top of "any"
blocklevel protokoll like parallel SCSI/iSCSI/SCSI via Fibre Channel and the
like or a distributed network filesystem like NFS.
2. Share any valuable data between all nodes. In this case the rootfilesystem
is the focus.
3. Establish a collection of tools and design practices to build such a
cluster (for example handle hostdependent files, initrd or build cluster
applications)
If we transfer it to your setup (as far as I understand your setup) there
should be not difference between a node and a sharedroot server. That means
apache/php/mysql and any other application runs on any open-sharedroot
node/server. It can run multiple times (if it is capable of being
loadbalanced over multiple servers - like apache with php) or one time (if
not - like mysql).
I hope that explains things a bit.
Regards Marc.
