--liOOAslEiF7prFVr Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi *, fsck(8) tell me about how to fsck filesystems parallel on a "per drive" basis: In preen mode, after pass 1 completes, all remaining file systems are checked, in pass number order running one process per disk drive in pa= r- allel for each pass number in increasing order. In other words: In preen mode all pass 1 partitions are checked sequen- tially. Next all pass 2 partitions are checked in parallel, one proce= ss per disk drive. Next all pass 3 partitions are checked in parallel, o= ne process per disk drive. etc. The disk drive containing each file system is inferred from the shorte= st prefix of the device name that ends in a digit; the remaining characte= rs are assumed to be the partition and slice designators. my /etc/fstab looks like this: /dev/ufs/ROOT / ufs rw 1 1 /dev/ufs/VAR /var ufs rw 2 2 /dev/ufs/USR /usr ufs rw 2 2 /dev/ufs/DATA2 /data ufs rw 2 2 /dev/ufs/SPACE /space ufs rw 2 2 /dev/ufs/MULTIMEDIA /data/multimedia ufs rw 2 2 /dev/ufs/HOME2 /home ufs rw 0 0 /dev/ufs/PRIVATE /private ufs rw 0 0 Some of the filesystems are on top of a partition/label, others are on=20 top of a geli device, others may be md-devices etc.=20 Is fsck able to find out the "real hardware"? Is fsck "geom-aware"?
