> If the case is, as speculated, that one mirror has bad data and one has good, scrub or any IO has 50% chances of seeing the corruption. scrub does verify checksums.
Yes, if the vdev would be a mirrored one, which it wasn't. There weren't any mirrors setup. Plus, if the checksums would have been bad, scrub would have to deteteced that. It would not have been to resolve it, but that wasn't the case. zpool status backupPool_01 pool: backupPool_01 state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM backupPool_01 ONLINE 0 0 0 c3t2100001378AC0253d0 ONLINE 0 0 0 c3t2100001378AC026Ed0 ONLINE 0 0 0 errors: No known data errors If one of the two devices would go bad, boom - that it'd be for the entire pool, but as long as the two devices work, it's okay. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
