Can a spare be added to an existing raid 5 array?
I do not see any way to do it.

I recently had cause to do this (I had to RMA my WD2000 which would only
work as a slave device - see previous thread). I could just replace the
disk since it was a PATA disk and the others I have are SATA.
It worked very nicely.
I am now wondering how this 'running with spare' state compares with the
original state (using the, now missing, disk).
Is it the same now?
Max.
