Yes. And there's no hard and fast number we can give you because runtime will depends on the amount and density of the metadata, the speed of the underlying storage, how much RAM you have and how badly corrupted the filesystem is. IOWs, runtime can vary from a few minutes to a few days as you vary those parameters, and there's really no way to tell in advance where in that massive variance any specific production filesystem will land. Doing a test run (xfs_repair -n) to get a ballpark figure during a planned downtime period is the only way you'll get any idea of the *best case* repair duration on a *clean* filesystem. But the moment repair finds corruptions, all guesses you can make about runtime go out the window...
ok, so I at least need to try & see how well xfs_repair does on a clean filesystem.
