what do you recommend for cluster fs ??

[Anand Gupta]

I was wondering what people use / recommend for a cluster fs for use with
xen ?

Also with this cluster fs, will the domU's be using flat files / lvm ? (it
should be the former as per my guess since these flat files will be stored
on the cluster fs, but then won't performance hit will be there for these
domU's ? )

I don't want to invest in a san/ nas solution, just looking for cost
effective. Right now i have a single server which i will use for the cluster
fs and slowly add more servers to the cluster as and when i need more space.
Atleast thats what i have thought till now.

All ideas are welcome.

I'm currently using a firewire external hard disk. When used with
the 
correct IDE-FW-chipset (Oxford are the only ones working), 4 hosts can 
connect to one disk concurrently.

The other cheap possibility is to use iSCSI (e.g. iet). Or NFS.

Doesn't really answer the "cluster FS" question, since that's just
shared storage. :)

GNBD + CLVM + GFS here.

Good point and of course true. I skipped the "cluster fs" part completely.

Now if the question were "What do you use for shared storage to be able 
to use
Xen migration", then I'd be ok.

You could also use CLVM to have your guests living on logical
volumes that are visible on all cluster hosts.

Could you please direct me some documentation/howto where i can get a feel
of it and see how to go about installing and using it ? I heard about the RH
Cluster Suite, however wasn't able to find any documentation to use it.

There's some docs linked off the Clustersuite dev pages:

Thanks for the link. Already tried looking there, however was confused. I
guess there is no other way then to try to find way in those docs itself.
