Installing DRBD9 on Proxmox VE
Adding the Repositories
This supports Proxmox HA but it does require a very high performance and stable network.
First, you’ll want to confirm that the correct repositories are in the sources.list on your Proxmox VE Cluster.
$ nano /etc/apt/sources.list
deb http://ftp.debian.org/debian stretch main contrib
deb http://ftp.debian.org/debian stretch-updates main contrib security updates
deb http://security.debian.org stretch/updates main contrib
deb http://download.proxmox.com/debian/pve stretch pve-no-subscription
Also, if you do not have Proxmox Subscription you should delete the Enterprise repository or comment it for a cleaner verbose when updating.
$ nano /etc/apt/sources.list.d/pve-enterprise.list
deb https://enterprise.proxmox.com/debian/pve stretch pve-enterprise
Installing DRBD on a Proxmox Node
Now do a dist-upgrade and install the latest PVE Headers.
apt-get update -y
apt-get dist-upgrade --fix-broken --fix-missing -y
apt-get autoclean -y
apt-get autoremove -y
apt-get install pve-headers -y
Once that’s out of the way, install the latest DRBD utilities, Kernel Modules, etc.
wget -O- https://packages.linbit.com/package-signing-pubkey.asc | apt-key add -
PVERS=5 && echo "deb http://packages.linbit.com/proxmox/ proxmox-$PVERS drbd-9.0" /etc/apt/sources.list.d/linbit.list
apt-get purge drbdmanage
apt-get update
apt-get install drbdmanage-proxmox drbd-utils drbdtop -y
That’s it!
