[Ocfs-users] Ocfs and EMC Powerpath

[Kendall, Kim]

We will certainly bump the kernel and ocfs version when the opportunity
presents itself. (Hard to do when the systems are in production)

Are you usinf PP 3 or PP 4? I saw in a PP doc (PP 3.0) that a kernel
rebuild is necessary.

We are using Powerpath with CX300's and Emulex HBA's, also with OCFS on
Red Hat 2.1 AS.

Kernel upgrades are the biggest issue that we have, as some of the
drivers are dependent on modules built for specific kernels, and if your
not careful you can have boot issues with them.

I would suggest at least kernel e59 and OCFS v1.0.14.

Powerpath may only be supported to v3.7 on that 2.1 platfrom, but I
would doublecheck that with EMC support matrix.

We had issues with iostat statistics as well, but they seem to be better
with the latest systat packages, so make sure you update that as well.

Other than that, they seem to work fine.

Hope that helps.
