(unless we are talking temporary removal and re-insertion?)nope, I'm talking about complete pair's crash when two disks die. I do understand that's the possibility of such outcome (when two disks in the same pair crash) is not high, but when we have 12 or 24 disks in storage...
then may 6-12 filesystems. overall probability of double disk failure is same, but you will loose 1/6-1/12 of data.
