Disable btrfs memory swap file
Hi Everyone,
I've got a Fedora 38 install (upgrade from F37). The install happened
with Anaconda. Anaconda created the compressed memory swap file. I
resized the disk and added a proper swap partition. Now I need to
modify /etc/fstab and disable the compressed memory swap file. In the
screen text below, /dev/nvme0n1p4 is the new partition.
My Google-fu really sucks today. I cannot find a discussion of it.
How do I modify fstab to remove the compressed memory swap file?
Thanks in advance.
