Resizing a btrfs Volume

If you are using a block device on a cloud provider for backups, LxRoot uses the btrfs file system to store these. If you increase the size of the block device or volume with your cloud provider, the backup system won't automatically see the new space until you resize the file system.

The command to perform the resize is:

btrfs filesystem resize max /mountpoint

Where /mountpoint is your specific backup mount point (for example, /backups).
