I have tried to make a swapfile since my system currently swaps to another drive that I wish to remove. I used the commands:
fallocate --length 16GiB swapfile to make a file with no holes mkswap -c -L swap0 /home/swapfile mkswap: /home/swapfile: warning: wiping old swap signature.

I do not know how to translate the "Invalid argument". This used to work, but it has been awhile since I did it. Did I leave something out?
Is this a btrfs filesystem ? Swapfiles on btrfs filesystems are not supported currently ( according to <https://btrfs.wiki.kernel.org/index.php/FAQ> ) .
No, the attempt was made on the zfs file system that /home resides on. I would not have tried on a btrfs file system. I have not figured btrfs out yet. Why so many sub volumes. Back in the old days, for single user systems, I used a single partition for the entire system. No worries about partition overflow. Only downside is that system upgrades were not so clean being on the same partition as user files. But now /usr/local, which was designed to hold desired user files, is on a btrfs sub volume. So backups are not so clean and user files are still threatened by upgrades. I am still trying to understand the philosophy of this design.
