Does scub report the errors repeatedly? There are no other scrub errors reported, I guess there are also no relevant messages in syslog. During transaction commit scrub is paused, so it''s not possible to verify a half-made superblock.> corrected errors: 0, uncorrectable errors: 0, unverified errors: 0david -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

So it seems that something that happened in the mean time fixed it.
