Hello, Thank you for your answers@Christian: The command takes 1s, and seem to work as you said# dumpfs sd1c | grep clean cgrotor 64 fmod 0 ronly 0 clean 0 @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)
How does mount detects the partition need a fsck, I feed like it does it very fast. I didn't mention that it's an encrypted partition from # disklabel sd1c # /dev/rsd1c: type: SCSI disk: SCSI disk label: SR CRYPTO From# disklabel sd0g | grep g: g: 68163807 36692448 RAID I didn't think it would make a difference first Regards Le lundi 2 avril 2018 à 00:59:42 UTC+2, Theo de Raadt <dera...@openbsd.org> a écrit : > > How can I know if the partition needs to be checked by fsck, I'd like to > > test that. > > Check the output of dumpfs. clean=0 means that the filesystem is > dirty and fsck should be run. It is cheaper to just run fsck. If it has no work to do, it finishes.
