The volume group of the boot drive (/dev/vg_localhost/) is irrelevant. Specifically, the raid disk /dev/md/127_0 is built from /dev/sdb1, /dev/sdc1, /dev/sdd1, where each partition takes the whole disk space. I had a regular boot drive (/dev/sda) and an lvm built on raid 5 (/dev/sdb, /dev/sdc, /dev/sdd). Fedora 11 can still see the Raid and everything works. When I upgraded, I used a new boot drive for Fedora 15, so I can physically swap the boot drives and boot into either Fedora 11 or 15. I think I must have missed something so I resort to group wisdom here.

If you need further assistance for md-raid, it's another good sign that you do not want to choose that technology.Lately I bit the bullet and upgrade my OS from Fedora 11 to Fedora 15, and I've been trying very hard to figure out why Fedora 15 can't see the Raid setup that I created in Fedora 11.

#SOFTRAID RAID 6 INSTALL#

Debian 10 - Install Proxmox VE on Debian Buster.Debian 9 - Install Proxmox VE on Debian Stretch.So, Proxmox projects do not support it to avoid that users run into these problems!įor non-production/unsupported setups, where you still want to use mdraid (please don't!), you can create the required RAID level during Debian installation and then install Proxmox VE or create RAID after install Proxmox VE. That means, if some data gets corrupted, which happens on any long-running system sooner or later, and you normally do not notice until it's too late. Mdraid has zero checks for bitrot, data integrity, and most filesystems on top do not provide that either. It will be re-evaluated for Proxmox VE 7.0. See the ZFS on Linux article for more information.ītrfs can actually be a very safe and functional choice, but it is not yet supported by Proxmox VE.

If you want to run a supported configuration, using a proven enterprise storage technology, with data integrity checks and auto-repair capabilities ZFS is the right choice.

Please note that Proxmox VE currently only supports one technology for local software defined RAID storage: ZFS Software RAID is an alternative for using hardware-RAID controller for local storage.
