How can I configure RAID10 on So you Start dedicated server?
I bought a dedicated server from So you Start with four 2T disks. I installed Proxmox VE on the first hard drive, how can I configure RAID10 in Proxmox VE. Or should I reinstall the OS?
I know the default RAID of OVH machine is RAID1, but I want to make full use of all disks. I tried a lot of methods by using mdadm, but failed. So can anyone provide instructions on how to do it?
Thanked by 1AndrewL64

I have minimal 4 HDD's? On server
Raid 1 minim 2 HDD
Raid 10 minim 4 hdd
To whom is that question directed at?
Also:
I would recommend to go via the Proxmox installer using zfs (if some kind of vnc is available).
Alternatively I think you could set up Debian and then "upgrade" to proxmox later, if you prefer an mdadm configuration
first think about a partitioning scheme. usually there is no need to absolutely put everything on a single large partition. proxmox for instance puts disk images and whatnot into /var/lib/vz which then is an ideal mount point for a split partition.
that said, here is what I did: use the SYS installer to install debian buster, but tick the box for individual settings/partitioning. then create a small /boot partition and a reasonable sized / as well as some swap. in that setup you'll notice that you can't choose raid 10 for / so go with raid-1 (across 4 disks) instead. leave a bigger part of the disks empty to create raid-x, zfs, lvm, whatever later (and mount it to /var/lib/vz)
after the install you can reshape the raid-1 which your / resides on to a raid-10 via mdam, but you need to go through raid-0 first. this is a good read: https://www.berthon.eu/2017/converting-raid1-to-raid10-online/
and yes this can be done online without kvm/ipmi.
after you did this you can partition the free disk space to your needs, I went for zfs/raidz but of course you can also just use mdadm to make it another raid-10.
proxmox can then be installed on top of debian: https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Buster
you just want to get rid of cloud-init so it does not mess up your network settings on each reboot.
I would recommend you to install Proxmox/OS on 2 disks as ZFS RAID 1
Then from Proxmox GUI add remaining 2 disks for storage as ZFS RAID1 again
and what did you smoke?
Oops.. looks like I smoked something else instead of weeds..
I just got a dedicated server from OVH with 4 ssd disks (Hardware raid) and is st as default to Raid 1 (as i can see from the total size of the disks when i am starting the installation of Centos 7.2. How can i change it to Raid 10?
Did you read this thread?
I'd like to thank @Falzo very much. Following the details Falzo provided, I finally made it.
But I messed up when I tried to install Proxmox on Debian, but it's ok. By the way, does anyone tried mergerFS and SnapRAID?
i'll read that thread, thanks for suggestion ! mobdro
