I believe there are commands to add and remove disks from the btrfs
during run-time.

Examples or references please.

btrfs filesystem resize [devid:][+/-]<newsize>[kKmMgGtTpPeE]|[devid:]max
Resize a filesystem

btrfs device add [options] <device> [<device>...] <path>
Add a device to a filesystem
btrfs device delete <device> [<device>...] <path>
Remove a device from a filesystem

Sorry, I didn't make myself clear.
It wasn't the specific commands I was asking about, it was the "during
run-time" I was questioning.

If course, if I boot from the CD in maintenance mode I can do all that,
since the disk if really off line, but if by "run time" you mean the
live system, while the file system is in use (as I do with ReiserFS), no
I haven't done that

What I'm asking about is not the commands themselves but a reference to
"during run time" in the sense of a live FS in use.
