Could anyone write a artilce about how to use hammer volume-add and
volume-del step by step?
I can't do it well.

You used it correctly and discovered a bug. It's really as easy as:

  hammer volume-add /dev/ad1 /

You can use whatever device, partition, slice etc. you want instead of /dev/ad1.

Note that if you extend you root filesystem, you'd also need to change

your /boot/loader.conf vfs.root.mountfrom setting to include ad1:

Before volume-add:

  vfs.root.mountfrom="hammer:ad0s1d"

After volume-add:

  vfs. root.mountfrom="hammer:ad0s1d:ad1"

Always keep in mind that volume-add and volume-del is still experimental, which means that it needs more testing!
