I wanted to delete a 150G Btrfs pool from my lxd server:
$ lxc storage show costorage1 config: size: 150GB source: /var/snap/lxd/common/lxd/disks/costorage1.img description: "" name: costorage1 driver: btrfs used_by: - /1.0/profiles/default status: Created locations: - none
And resize it to 50G or delete it and create a new pool with 50G.
lxc profile device remove costorage1 root
However, that did not help to accomplish freeing the space from the system.
I still see the
212G of space used on my system:
$ df -h Filesystem Size Used Avail Use% Mounted on udev 7.8G 0 7.8G 0% /dev tmpfs 1.6G 2.1M 1.6G 1% /run /dev/sda2 234G 212G 9.8G 96% / tmpfs 7.8G 67M 7.8G 1% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 7.8G 0 7.8G 0% /sys/fs/cgroup /dev/loop1 9.2M 9.2M 0 100% /snap/canonical-livepatch/95 /dev/loop2 162M 162M 0 100% /snap/gnome-3-28-1804/128 /dev/loop3 256M 256M 0 100% /snap/gnome-3-34-1804/36 /dev/loop4 218M 218M 0 100% /snap/gnome-3-34-1804/60 /dev/loop5 63M 63M 0 100% /snap/gtk-common-themes/1506 /dev/loop6 69M 69M 0 100% /snap/lxd/17629 /dev/loop0 98M 98M 0 100% /snap/core/9993 /dev/loop7 56M 56M 0 100% /snap/core18/1885 /dev/loop8 97M 97M 0 100% /snap/core/9804 /dev/loop9 261M 261M 0 100% /snap/kde-frameworks-5-core18/32 /dev/loop10 50M 50M 0 100% /snap/snap-store/467 /dev/loop11 55M 55M 0 100% /snap/core18/1880 /dev/loop12 44M 44M 0 100% /snap/snap-store/415 /dev/loop13 31M 31M 0 100% /snap/snapd/9279 /dev/loop14 30M 30M 0 100% /snap/snapd/8790 /dev/sda1 511M 7.8M 504M 2% /boot/efi tmpfs 1.0M 0 1.0M 0% /var/snap/lxd/common/ns tmpfs 1.6G 28K 1.6G 1% /run/user/1000
So I removed the whole lxd using
snap remove lxd
After this, I rebooted my system and although lxd was gone, the disk space is still present somewhere.
/dev/sda2 234G 212G 9.8G 96% /
I re-installed lxd using
snap again and ran
lxd init, I was not able to find the previous storage pool
costorage1, so I created a new one with the default 30G.
$ lxc storage info storage1 info: description: "" driver: zfs name: storage1 space used: 620.54kB total space: 28.61GB used by: profiles: - default
How can I safely remove that other 150G from the old Btrfs pool from my Linux system?
Thanks for any suggestions.
