In the How-to (http://wiki.contribs.org/AddExtraHardDisk), there is a line in the intitial disclaimer that says:
Consider also that if this disk fails the whole system goes down.
I don't understand why that would be. If it was the SME LVM extended out to this disk (as in the discussion portion of the how-to) then I could see that being an issue. But if it is simply configured as an extra disk and then have symlink used to access it, I would expect that if you lost that drive you only lose access from the symlink but the rest of the system will run fine.
BTW, I'll be updating the How-to for adding an extra RAID set as opposed to just a single drive.

Well I've tested the scenarios I can think of with the How-to and the worst I can see happening is that if it is in fstab with the options specified (ie. fsck). If there is a fatal disk errror then the system will stop at during boot at the fsck test. From there you can drop to the shell and remove the disk in fstab (or array) and then reboot and later fix your troubled system.
I'll update the how-to accordingly.
BTW, is there a better way to load the extra disk? Ideally I would like to load the disk automatically, do an fsck but not fail the system boot because of it. I'm not sure if there is an fstab option for this.
The only other way I could think of was to add something into rc.local or an earlier script.
