I thought this was supported with the a resync - you can break the mirror, use it, then resync it, all without a full sync.

This is certainly possible with VxVM 3.2 for Unix, where you have additional objects to maintain metadata about where an off-split mirror differs from the on-line mirror. This represents yet another license to buy.

Without such a fast resync option, the whole mirror does need to be resilvered, and that does get painful.

I'd imagine other volume managers may have similar functionality.
