You can have up to 2 MDSs, configured in an active/passive failover
configuration.  You cannot have more than one MDS actively handling
requests at a time.

Lustre 2.x will support the clustering of metadata servers.

This is correct.

The Lustre administrator and operations manual describes additional
configurations.  It is included with all support contracts, but is not
available for free download.

Your proposed configuration is not going to be very different from your
current one, because there will only be:

- 1 node acting as MDS+OSS
- x nodes acting as OSS only
- y nodes acting as clients only

Hope that helps--

Hello,
 
I am configuring Lustre FS on our cluster and have a few questions:
 - used LustreHowto document dated  3/17/04.
 - used Lustre 1.0.4 with Linux 2.4.20 and configured a single mds node,
multiple ost nodes and multiple clients. Each node was configured as a
single type.
 - does 1.0.4 supports multiple mds? If it does, how do I configure
multiple mds? I used Lustre Lite 0.7 last year and it only supports
single mds.
 - I understand that with 1.0.4, ost and client cannot coexist on a
single node. I assume that mds and ost can coexist on a single node, am
I  correct? If it is,
   I would like to configure with equal number of client nodes and
mds/ost nodes.
 - is there any other documents besides the LustreHowto that describes
more complex configuration? 
 
Thank you in advance?
