ProxMox

Community Scripts

There is a lot of extremely helpful scripts for installing various things on ProxMox: https://community-scripts.github.io/ProxmoxVE/scripts.

Post-install

# bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/misc/post-pve-install.sh)"

Running Docker Containers

In ProxMox shell, run the community script:

$ bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/vm/docker-vm.sh)"

To make arrow keys etc. work when connected to the container over SSH and such, inside the container make the symbolic link from /bin/sh to /bin/bash.

File Store

In ProxMox shell:

# lvcreate -V1T -T pve/data -n store
# mkfs.ext4 /dev/mapper/pve-store
# mkdir /mnt/store

In /etc/fstab on ProxMox, add:

/dev/pve/store /mnt/store ext4 0 1

And then mount:

# mount /mnt/store

To mount a directory from the host in a container, in the ProxMox shell:

$ pct set <container id> -mp0 /path/on/host,mp=/path/in/container

RAID File Store

I added a bunch of hard disks to my ProxMox box and created a BTRFS RAID; this is where I want to store my photographs and other media.

I perused:

• Arch Btrfs documentation
• ProxMox BTRFS documentation
• Create Btrfs Storage Pool on Proxmox Manually

If at some point I decide to add my RAID as storage to ProxMox:

• Storage
• Storage: Directory
• Storage: BTRFS

ProxMox shell commands for the record:

## get rid of the stale madm RAID membership metadata
# wipefs -af /dev/sdc
# wipefs -af /dev/sdd
## reboot for ProxMox to re-read disks metadata
## make the RAID filesystem
# mkfs.btrfs -draid1 -mraid1 /dev/sdc /dev/sdd -L "Big Data"
## get UUID etc.
# btrfs filesystem show /dev/sdc # or /sdd
## create mountpoint
# mkdir /mnt/data
## in /etc/fstab, add:
UUID=<UUID> /mnt/data btrfs defaults 0 1
# systemctl daemon-reload
## mount
# mount /mnt/data
