Unless the failed disk is the parity, in which case the 36gb will be used.
[...]
If it fails over to the 36GB drive when an 18 is available, I would consider that a bug.
The largest spare available will always be used to rebuild a parity disk, regardless of its original size (from the SA Guide). Just closed the PDF, but it was under 'managing disks'.
Putting only 1 of a larger disk is always a dangerous thing, as you're essentially running w/o a spare.
I don't follow what you mean here. He's talking about only one 36GB drive and having it be a "second spare". (Presumably this is safer than having only one global spare available, since you want it to use the 36GB in case the other raid group fails before you can replace it.)
Ah, I must have gotten lost in the thread.. I had thought this was an attempt to start adding 36's and force a fail to move to the new disk.
