Greetings to Proxmox team. Good work!
For years using VMW srv. and ESX on various HW, I had hard time set up ESX on Supermicro with H8DMT-F based on MCP55 chipset. After migration to VE, I thought my problems vanished. Unfortunately, after upgrade from 2.3 to 3 I was stuck with recovery console, PVE/LVMs disappeared, just only /dev/sda1 readable. I had to reinstall, which brought up certain question:
What's the benefit of rootfs being on LVM? Moreover - such a huge rootfs?
In case something went wrong, it's difficult to get into rootfs. I had to dig one of two HDDs out (to have intact data just for sure) and fiddled with LVM recovery. Very unpleasent experience with limited tools of recovery initramfs.
Meanwhile, I lost the confidence with MCP55 (pseudo) RAID, I decided to step into unsupported waters of mdadm - and so far, over the weekend no problems rose. And just for sure, I migrated the rootfs from pve/root onto /dev/md1, somehow reducing it's size.
