Experimenting with OpenSolaris on an elderly PC with equally elderly drives, zpool status shows errors after a pkg image-update followed by a scrub. It is entirely possible that one of these drives is flaky, but surely the whole point of a zfs mirror is to avoid this? It seems unlikely that both drives failed at the same time. Could someone explain how this can happen? Another question (perhaps for the indiana folks) is how to restore these files?
If a corruption occured in the main memory, the backplane, or the disk controller during the writes to these files, then the original data written could be corrupted, even though you are using mirrors. If the system experienced a physical shock, or power supply glitch, while the data was written, then it could impact both drives.
