[Pvfs2-users] linux vserver and PVFS2

[Eugen Leitl]

I'm planning to eventually operate a 20+ node cluster of Debian boxes
(2-4 cores AMD64, 8 GByte RAM, about 1-2 TByte RAID 1, 4x GBit Ether
interfaces, probably with jumbo frames) with a unified filestore.

A few questions I've been unable to answer by searching:

Can I make Linux vserver guests fs live on PVFS2? 
If I don't use unification http://linux-vserver.org/Frequently_Asked_Questions#Unification
?

How much aggregate throughput can I expect with some 20
nodes, with a modern 7 krpm SATA drive (RAID 1 pair, about
80 MByte/s sustainable throughput, or so)?

Is there a way to set up PVFS2 to tolerate 1-2 node losses on
above 20-node assembly, and how much of the raw storage would I lose 
that way? 

Thanks,
