I have used this for years for major in place upgrades where i was in doubt
of outcome and it has saved my bacon on several occasions. BE SURE you know
what you are doing with your RAID controller and only do it with hardware
Raid. Also be sure you have a real Total Backup as well.

We are running a raid 1 setup. We are thinking if we could use raid as an
auxiliary (not prinicpal) backup strategy prior to installation, update or
configuration work to have a painless fallback in case anything goes
wrong.
The procedure would be the following:
1. Prior to installation work, retire one of the two raid disks and
replace
it with a new one. (This may happen with the machine off)
2. Wait for both disks to be synchronized.
3. Perform installation, update, configuration
4. If everything performs to spec leave current configuration.
5. If fallback is needed, shutdown machine, remove both disks, replace one
with safeguarded one, startup on that disk, once up and running insert
other
disk and synchronize.
I'd appreciate your opinion wether this is good (or even common) practice
or
wether there are any considerations that I am not aware off.
