Re: Check if fsck will be run on a partition

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

It is cheaper to just run fsck.  If it has no work to do, it finishes.
