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.
