Is there a recommended way (or tool) to shrink a btrfs partition?
I have:
root@zoo:~# lsblk -o NAME,SIZE,FSTYPE,MOUNTPOINTS /dev/sdc
NAME SIZE FSTYPE MOUNTPOINTS
sdc 256G
`-sdc1 256G btrfs /LXC
root@zoo:~# df -Th /LXC
Filesystem Type Size Used Avail Use% Mounted on
/dev/sdc1 btrfs 256G 19G 236G 8% /LXC
And want to shrink /dev/sdc1 to 200 GB
I know, I can use btrfs filesystem resize and afterwards use fdisk to
delete /dev/sdc1, create a new smaller /dev/sdc1 and then add a new
/dev/sdc2
BUT if make a calculation error with fdisk the btrfs filesystem will be
damaged.
gparted can do it all together in one step, but it needs X11, which I do
not have on host zoo. I have only text console access, no X11.
