Switching LXD Storage Pools
By chimo on (updated on )
Short post so I remember how I moved my containers from a "dir"
storage pool to btrfs.
I found the answer here. Turns out it’s pretty simple. I have about 27 containers at the moment, which isn’t a huge lot, but enough that I didn’t want to run these commands manually for every container. I ended up using the following script to migrate my running containers to the new storage pool:
#!/bin/bash
mapfile -t containers < <(lxc list status=running -c n --format csv)
for container in "${containers[@]}"
do
echo "Stopping ${container}..."
lxc stop "${container}"
echo "Renaming ${container}..."
lxc move "${container}" "${container}"-tobemoved
echo "Moving ${container}..."
lxc move "${container}"-tobemoved "${container}" --storage=btrfs_pool
echo "Starting ${container}..."
lxc start "${container}"
done
