Re: Lustre and EMC PowerPath for Failover/Load Balancing

Jeff,

Do you have both device-mapper and device-mapper-multipath rpms installed
on your systems?

High performers are recognized not just for reaching the peak, but for
staying there.

Hello,
Because PowerPath requires official distribution kernels, I don't
think it's possible. We're currently using a lustre kernel with the
multipath open source tools. In RHEL 4,5 the rpm is called
device-mapper-multipath.
Thanks,
                         -jeff
