You can only hot-remove a disc that is failed.
The safest way to "fail" a disc is to use
raidsetfaulty /dev/md0 /dev/sdb1
If you don't have raidsetfaulty (so RedHats don't have it), grab the
latest raidtools from
http://www.{country}.kernel.org/pub/linux/daemons/raid/alpha/raidtools-19990824-0.90.tar.gz
and compile it for youself. Don't worry about the "alpha".
