The swapon(8) man page says:
The swap file implementation in the kernel expects to be able to write to the file directly, without the assistance of the filesystem. This is a problem on files with holes or on copy-on-write files on filesystems like Btrfs.
As I'm getting OOM errors when I try to run a VM, it looks like I need a swap file or partition. I'd prefer to use part of my (large) SSD for this, but currently it's entirely formatted as BTRFS. Do I need to resize the BTRFS partition rather than using a swap file?
Yes. But have you enabled zram yet for swap?
