First, but based on what you've written, you really need to read up on
what RAID 1 *is*.
Second, when you say you removed /dev/sda, did you take it out of the box,
or just swap positions? If the latter, then a) the system still sees it as
sda: that's not something you've made any changed to - the system will
look for a LABEL or UUID, b) if you did take it out, and replace it with
another, new, physical drive, then there will be RAID messages saying it's
rebuilding, and c) if you just took it out, and there's only the one
drive, the former /dev/sdb, you will be seeing tons of messages that RAID
is degraded.
