We think this is a serious bug ourselves. It happens to more than spares - kinda weird behavior to be sure. That's why we have at least 2 spares per filer, and we jump all over failed disks.

It seems to me that spares are just allowed to sit, and aren't checked for availability or that they can be read/written at all? Ever?

Somehow I see this as a potential gotcha! You have carefully reserved a spare and then loose a disk and low and behold no spare!

Thinking about this removes some of the warm fuzzy feeling that owning a toaster gives one.

Any comments from the experts? Netapp? Can we make this a RFE, something to the effect that at scrub time all spares will be checked for availability and that (at least) some piece of them can be read and written?
