Hi folks, I got two IBM x3550M4 with Emulex double-8gbit FC cards and one IBM DS3512 FC SAN directly connected.
I've setup multipath correctly (from IBM papers for linux) and blacklisted the devices in lvm.conf.
CentOS works great and gives absolutely NO errors.
With exactly the same configuration of multipath.conf and lvm.conf, ProxMox gets lots of I/O errors on startup (dramatically slowed down due to thousands of errors) and also every "n" seconds, causing incostant performance compared to CentOS.
It seems like udev is trying to get information about the "fake" devices sdb and sdc (used for multipath).
I discovered that ProxMox and CentOS have exactly the same version of lpfc drivers.
What would you suggest?
