I have a disk which apparently has no disklabel, but still boots and mounts several partitions, and I'm puzzled as to how this can be. Where is it pulling the partition information from if not the disklabel? $ df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ad6s1a 128990 48054 70618 40% / /dev/ad6s1f 257998 18 237342 0% /tmp /dev/ad6s1g 151150778 2131440 136927276 2% /usr /dev/ad6s1e 257998 7546 229814 3% /var procfs 4 4 0 100% /proc $ disklabel ad6 # /dev/ad6: type: unknown disk: amnesiac label: fictitious flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 19457 sectors/unit: 312581808 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 312581808 0 unused 0 0 # (Cyl. 0 - 19457*) $ disklabel -r ad6 ~ disklabel: bad pack magic number (label is damaged, or pack is unlabeled) If I boot off the fixit CD, I can't see or mount any FreeBSD partitions on the disk. This is on a HP Proliant DL360 Gen 4 with a single Maxtor 160GB SATA drive running FreeBSD 4.10. Thanks, Pete Yandell
