I'm thinking about implementing gluster as a possible way of home
directory server redundancy(using the afr translator), but I have a
few questions that I can't seem to find the answer to:
-Does installing gluster require a total format of the "bricks" or
data volumes involved? Can I just install it over the current system
and keep data intact? From what I read it just works over the current
filesystem (ext3, xfs, etc)?
-We currently have a single node w/fibre channel raid (partitioned
into 7 luns for different user groups) for our home directories. All
exported using NFS. We are getting in a new server and raid unit,
which will become the primary server once it is setup. Can I setup
the new server and raid as a single gluster node, get the data copied
over (via rsync or something similar), move clients over to the new
machine, then resetup the old server/raid combo and add it into the
gluster system? Or is there a better way to do this?
-Concerning NFS and tied into the above question: we use it for it's
compatibility with Mac, Linux and Solaris workstations and has worked
fairly well. We'd like to stick with it. Would that require running
a fuse/gluster client on one of the above nodes and re-exporting it as
NFS? That is the way I seem to understand from my searches on the
mailing lists. Or can you directly export a gluster brick via nfs?
And if running the fuse/gluster client on one of the server nodes w/
exported NFS is necessary, is this a safe way to do things?
Any helpful hints, tips or different ways of thinking about things is
p.s. sorry for all of the questions...I'm a bit new at attempting
