Is there a recommended way to replace a corrupted file or directory on btrfs? The use case I'm thinking of is handling filesystem corruption by restoring only the corrupted files from backup. For a corrupted file, it seems like deleting the file and replacing it with the copy from the backup works, but I don't know if this is necessarily the best way - the nature of copy-on-write means that there's still corrupt data lying around on the filesystem, right? And for directories, it's tricky, because (afaik) there's no way to delete a directory without first walking it; not good if it's corrupted.
I think this is probably also relevant to something like Ceph or CRFS, where redundancy exists, but isn't managed by btrfs directly. -- 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
