Hi, I've (re)scanned my -current folder for issues related to the following but didn't see a good match. Pointing out my blindness is allowed if this was discussed... I have a system onto which I installed a 4.7-RC a couple of weeks ago. I then upgraded that newly installed system to -current. After the upgrade, disklabel now complains about every disk in the system, for example: # disklabel -r ad6s1 # /dev/ad6s1c: type: unknown disk: amnesiac label: flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 16 sectors/cylinder: 1008 cylinders: 193820 sectors/unit: 195371505 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] a: 195371505 63 4.2BSD 2048 16384 28512 # (Cyl. 0*- 193820*) c: 195371505 63 unused 0 0 # (Cyl. 0*- 193820*) partition a: partition extends past end of unit partition c: partition extends past end of unit Warning, partition c doesn't start at 0! Warning, An incorrect partition c may cause problems for standard system utilities # This is an fdisk'd drive, with the entire disk allocated to the 1st slice. An identical disk (ad4): ad4: 95396MB <WDC WD1000JB-32CWE0> [193821/16/63] at ata2-master UDMA100 ad6: 95396MB <WDC WD1000JB-32CWE0> [193821/16/63] at ata3-master UDMA100 which I then fdisk and disklabel under -current shows up as: 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 195371505 0 unused 0 0 # (Cyl. 0 - 193820*) The only difference being the offset of 0 (and lack of warning msgs). Both systems come up with the same disk size, but the offsets not matching seems to be a problem. An older 4.7 pre-release system from Sep 16 creates the 'c' slice with an offset of 0. I don't think this is something I did wrong. Any thoughts, comments, or pointy hats are welcome.
