Subject: How to convert a directory to a subvolume

Hi,

I just installed Ubuntu 22.04 with a btrfs raid1 root filesystem.  I want to convert a directory, like /opt, into a subvolume. I haven’t been having much luck.  /opt is empty right now, so it’s a good candidate for conversion.  Could someone please explain how to do it?  I’ve been at a dozen different websites, & tried different variations of the “btrfs subvolume create” command, but nothing works when I go to mount it.  I think I’m missing something simple, but not sure what it is.

Thanks!

    -John
