Hello everyone !
I tried a dedicated server at OVH and tried to install several BSDs...
It is entirely possible to install OmniOSce (r151046 LTS and the latest r151052) on this dedicated server "KS-STOR | Intel Xeon-D 1521" at OVH.
The process is simple, whereas you can not use any installer version (.iso, dd-usb) nor OVH template with cloud.qcow2 image. You must use the cloud.raw image.
Boot into rescue mode (debian-10), restart your server then log in via SSH
ssh root@SERVER-IP
List the storage devices connected to the server :
lsblk
Erase the disks (not mandatory.. your choice)
nohup dd if=/dev/zero of=/dev/sda bs=1M &
nohup dd if=/dev/zero of=/dev/sdb bs=1M &
nohup dd if=/dev/zero of=/dev/sdc bs=1M &
nohup dd if=/dev/zero of=/dev/sdd bs=1M &
nohup dd if=/dev/zero of=/dev/nvme0n1 bs=1M &
If you don't want to erase the NVMe entirely, you really should erase the beginning and the end to be sure that there isn't an old ZFS pool label (I had a previous zpool from my FreeBSD installation on it which made the server crash after 5min the first time - FAULTED rpool) :
zpool labelclear -f /dev/nvme0n1
dd if=/dev/zero of=/dev/nvme0n1 bs=1M count=100
dd if=/dev/zero of=/dev/nvme0n1 bs=1M seek=$(( $(blockdev --getsz /dev/nvme0n1) * 512 / 1024 / 1024 - 100 )) count=100
Monitor when the erase operations are complete:
ps -ef | grep 'dd if=' | grep -v grep
Install parted, zstd, fwupdmgr
apt update
apt install parted zstd fwupdmgr -y
Update the firmware (yes you should do it ! I had a strange problem on one server ! Did not work without this :-S)
fwupdmgr refresh
fwupdmgr get-updates
fwupdmgr update
Create GPT tables on the disks (again, not mandatory, just to clean...)
parted /dev/sda mklabel gpt
parted /dev/sdb mklabel gpt
parted /dev/sdc mklabel gpt
parted /dev/sdd mklabel gpt
parted /dev/nvme0n1 mklabel gpt
Download the OmniOSce cloud.raw image and uncompress it
wget https://downloads.omnios.org/media/stable/omnios-r151052.cloud.raw.zst
zstd -d omnios-r151052.cloud.raw.zst
Burn the image to one of the HDDs:
dd if=omnios-r151052.cloud.raw of=/dev/nvme0n1 bs=1M status=progress
sync
Import the pool:
zpool import
zpool import -f rpool
Mount it:
mkdir -p /mnt/root
mount -t zfs rpool/ROOT/omnios-r151052 /mnt/root
Add your public SSH key:
mkdir /mnt/root/root/.ssh
echo "YOUR-PUBLIC-SSH-KEY-HERE" > /mnt/root/root/.ssh/authorized_keys
Export the pool
zpool export rpool
In your OVH interface, set the boot to disk this time (instead of rescue).
Restart the server and use the IPMI/KVM console (via your web browser, for example... it works very well with Firefox contrary to what is said) to watch the server boot from the raw image.
It will stop displaying after : "Loading /boot/defaults/loader.conf"...
But goes on...
Wait for 1-2 minutes more, erase your local known_hosts file then connect by SSH:
ssh root@IP-SERVER
Tadam !
