There's really no way to recover from this, since we don't have device removal. However, I'm suprised that no warning was given. There are at least two things that should have happened:
1. zpool(1M) should have warned you that the redundancy level you were attempting did not match that of your existing pool. This doesn't apply if you already have a mixed level of redundancy. 2. zpool(1M) should have warned you that the device was in use as an active spare and not let you continue. What bits were you running? - Eric On Tue, Jan 15, 2008 at 06:25:50PM -0800, Ben Rockwood wrote: > I made a really stupid mistake... having trouble removing a hot spare > marked as failed I was trying several ways to put it back in a good > state.
