Good afternoon!

Tell colleagues, there is a /tmp/swapfile created like this:

dd if=/dev/zero of=/tmp/swapfile bs=1M count=4096
mdconfig -a -t vnode -f /tmp/swapfile -u 0

The swapoff -a command for some reason does not disable the swap ... I want to delete it. Is it possible to just delete the swap file without any consequences?

Probably because the command has mdconfig -a -t vnode -f /tmp/swapfile -u 0nothing to do with the swap file?

Can. But disk space will not be released while the swap file is in use.
