Today, if one tries to repair a filesystem with a realtime subvol but forgets to specify the rtdev on the command line, the result sounds dire: Phase 1 - find and verify superblock... xfs_repair: filesystem has a realtime subvolume xfs_repair: realtime device init failed xfs_repair: cannot repair this filesystem. Sorry. We can be a bit more helpful, following the log device example: Phase 1 - find and verify superblock... This filesystem has a realtime subvolume. Specify rt device with the -r option.
