Is Linux MD software smart enough to rewrite a bad sector with good data to clear this type of error (keeping track of error counts to know when to eject the disk from the array)? What about btrfs/zfs? Trickier with something like ceph where ceph runs on top of a filesystem which isn't itself redundant...
I've seen Linux MD keep all disks in the array after a read error was reported on one disk, so presumably it did that as the error wasn't repeated. But you really want ZFS or BTRFS to cover the case where corrupt data is claimed to be good. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
