WebIn order to switch, you have to unmount the filesystem, remove the previous space cache, then mount it with the space_cache=v2 mount option. This will be a permanent change and Btrfs will use the new Free Space Tree on all future mounts once enabled. Removing the old v1 space cache is done with btrfs check . Web/dev/sdc2 (a 58 GB partition on the SSD) is initialized as a cache device, and connected to both bcache0 and bcache1. /dev/bcache1 and /dev/bcache2 are used as LVM physical volumes (PVs), forming volume group vg0. /dev/mapper/vg0-root is the btrfs formatted root file system (linearly mapped onto the PVs)
