So is the conclusion that all the csum errors are in the metadata? What is the profile of the fs? ( not dup for metadata I assume?) I also have a WD40EZRX and the fs on it is also almost exclusively a btrfs receive target and it has now for the second time csum (just 5 ) errors. Extended selftest at 16K hours shows no problem and I am not fully sure if this is a magnetic media error case or something else. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
