Hi,
I've done some searching on degraded volumes but it's not clear to me if my drive actually needs to be replaced or if there's something wrong with the RAIDz itself.
How do I recover from this? The drive, ada4, seems to be reporting healthy from a SMART perspective but from the RAIDZ side it's degraded. Details follow.
Thanks.
