Hi I've got an issue with my TB Chromebook 2 with galliumOS where I installed encrypted without editing any of the swap size partitions manually and now I've ran out of storage and want to either reduce the size of the encrypted swap or completely delete it and make a USB stick to be my swap partition.

Can anyone help? I'm trying to use lvs and other logical volume commands but it says the correct packages are not installed or have missing dependencies.

It'd be easy if I could change the crypttab to do this but from research have found this not to be do-able.

Any ideas?
