Feel free to add/update/delete entries or suggest new corrupt ideas! Thanks for doing that. About the test "Device-corruption", I suppose that you want to test a scenario where one disk fails. If so you do not have to always corrupt "D0" block, but the first block of the file which is stored in the failing disk (which could be different from the D0). Another scenario which should be tested, is the reshaping of the raid: add a drive (or remove a drive) then re-balance the system (with or without some corruption). IIRC this use the same scrub code. > > Cheers. > Lakshmipathi.G > -- BR G.Baroncelli -- gpg @keyserver.linux.it: Goffredo Baroncelli <kreijackATinwind.it> Key fingerprint BBF5 1610 0B64 DAC6 5F7D 17B2 0EDA 9B37 8B82 E0B5 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
