I'm curious why. The usual way is to run fsck, look at errors and call with --repair eventually, expecting the repair mode do fix what's fixable. Now this would not return the same set of errors in the non-repair mode? This of course depends on the damage of the filesystem, but I think we should try to let it continue as far as possible and then stop. This probably means extra checks of the data structures before use, but this a good pattern for fsck anyway. > + > info = open_ctree_fs_info(argv[optind], bytenr, 0, ctree_flags); > if (!info) { > fprintf(stderr, "Couldn't open file system\n"); -- 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
