You seem to be confused. fsck will print stuff about the number of files and fragmentation etc only if was actually needed to check the file system. This is a line for informational purposes only, it does not signal any problem. In the normal (clean) case, it will print $ doas fsck /usr/obj ** /dev/sd0h (6a41a900f61a2dc6.h) ** File system is clean; not checking $ On a side note read the FAQ about creating filesystems http://www.openbsd.org/faq/faq14.html. It is not recommended to create a filesystem on the c (whole disk) partition. -Otto > > > Le lundi 2 avril 2018 à 14:08:45 UTC+2, Nick Holland > <n...@holland-consulting.net> a écrit : > > On 04/02/18 02:28, Mik J wrote: > > > @Theo: The fsck is not superfast, it takes 20s I end with that message39256 > > files, 5904368 used, 10865841 free (15345 frags, 1356312 blocks, 0.1% > > fragmentation) > > you missed his point. > > If it took 20 seconds to run, you needed to run it. > If you didn't need to run it, it would have said the file system was clean. > > Watch: > > # umount /var/www > > # time doas fsck /var/www > ** /dev/sd2p (30b584a557ce1aea.p) > ** File system is clean; not checking > 0m00.07s real 0m00.00s user 0m00.01s system > > # doas mount -a > > That's a 200G partition, btw. > > I think less than a tenth of a second is quite good.
