Hello,
i'am trying to compile the 1.6.5 sources against a vanilla-2.6.22.19 kernel.
Distrib: gentoo 2008
- setting the links and patching the kernel as described with "quilt push -av"
ok.
- compiling and booting the kernel ok.
- configuring lustre:
./configure --disable-liblustre --enable-quota

Hello,
the docs state for a failover setup that the MDS and MDT should be on seperate
nodes.
Therefore we would like to know what a "good" scenario could be. Does it make
sense or is it even possible to setup a MDS with failover capabilities, i.e.
something like (mirrored with DRBD here for ex

Hello,
we have a _test_ setup for a lustre 1.6.5.1 installation with 2 Raid Systems

server (32 Bit system , for testing only).
OST lustre mkfs:

Actually i wasn't aware of the differences between set_param and config_param.
