[SOLVED] Cannot delete a btrfs subvolume...

Hello, I have got this:

[frankenstein@coprinus ~]$ sudo btrfs subvolume list -p /
ID 257 gen 1125178 parent 5 top level 5 path @
ID 258 gen 1125162 parent 5 top level 5 path @snapshots
ID 259 gen 1125178 parent 5 top level 5 path @home
ID 261 gen 58408 parent 257 top level 257 path var/lib/machines
ID 428 gen 58408 parent 257 top level 257 path var/lib/portables
ID 980 gen 1125175 parent 5 top level 5 path @swap
ID 996 gen 1125162 parent 258 top level 258 path @snapshots/root-231019

And I am trying to delete the @swap subvolume but whether I issue:

[frankenstein@coprinus ~]$ sudo btrfs subvolume delete @swap
ERROR: Could not statfs: No such file or directory

or:

[frankenstein@coprinus ~]$ sudo btrfs subvolume delete /.swap
Delete subvolume (no-commit): '//.swap'
ERROR: Could not destroy subvolume/snapshot: Invalid argument

It clearly isn't working.

Does anybody know how to do this?

Thank you...

Okay I got that one fixed, I had to:

sudo mount /dev/mapper/cryptroot -o subvolid=5 /mnt

And then:

sudo btrfs subvolume delete /mnt/@swap

Thanks for posting the solution! I was struggling with the same. Ofc, in retrospect, it makes sense that you have to mount the partition and not the root subvolume to access and delete the other subvolumes.
