[Gluster-users] GlusterFS as underlying Replicated Disk for App Server

[Dan Hawker]

Hi All,

We have a requirement for a common replicated filesystem between our two
datacentres, mostly for DR and patching purposes when running Weblogic
clusters.

For those that are not acquainted, Weblogic has a persistent store that it
uses for global transaction logs amongst other things. This store can be
hosted on shared disk (usually NFS), or in recent versions within an Oracle
DB. Unfortunately, some of the products that we use, have to use the disk
option.

Ordinarily I'd just follow Oracle's guidelines and use an Enterprise NAS
head and NFS, however the NAS head we have at my present role, has rather
lacklustre replication granularity (every 5mins), which just won't cut it,
so we're looking at alternatives, including throwing more cash at the
storage vendor.

The Linux team here use GlusterFS to host and replicate their Puppet
infrastructure between the datacentres. They like and understand it, and
say it's got good performance, so we were wondering if we could also
leverage Gluster for the persistent data stores that can't be DB hosted.

Wondered if anyone has tried this kind of thing with Weblogic or any other
JEE app server before, and if it is feasible. We'll obviously test this
extensively, but before we do spend time and resource, we're just after
some degree of confidence that it may work at all.

Thanks

Dan
