I had similar problems to Kai, but I remembered the changes, so no panic. what I cannot get round is this: (please bear with me) I am running current (ctm 471) with a 2-3 day old kernel. > Mar 31 12:42:49 grunt /kernel: sd0s4: start 1, end = 412359, size 412359: OK > Mar 31 12:42:49 grunt /kernel: sd0: rejecting partition in BSD label: it isn't entirely within the slice (**) > Mar 31 12:42:50 grunt /kernel: sd0: start 1, end 412359, size 412359 > Mar 31 12:42:50 grunt /kernel: sd0d: start 0, end 415599, size 415600 (x3) (**) This I can fix by getting rid of the "d" partition, right? EXCEPT I get this when I exit disklabel: > # /dev/rsd0c: > type: SCSI > disk: > label: MBR based label > flags: > bytes/sector: 512 > sectors/track: 61 > tracks/cylinder: 4 > sectors/cylinder: 244 > cylinders: 1689 > sectors/unit: 412359 > rpm: 3600 (was zero) > interleave: 1 (was zero) > trackskew: 0 > cylinderskew: 0 > headswitch: 0 # milliseconds > track-to-track seek: 0 # milliseconds > drivedata: 0 > > 4 partitions: (was eight) > # Hsize offset fstype [fsize bsize bps/cpg] > a: 40960 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 167*) > b: 65536 40960 swap # (Cyl. 167*- 436*) > c: 412359 0 unused # (Cyl. 0 - 1689*) > e: 305152 106496 4.2BSD 1024 8192 16 # (Cyl. 436*- 1687*) [exit] > Warning, unused partition e: size 305152 offset 106496 > disklabel: ioctl DIOCSDINFO: Open partition would move or shrink > re-edit the label? [y]: n 1) What does the DIOCSDINFO mean? 2) e is most certainly not unused! The logfile continues: > Mar 31 12:42:50 grunt /kernel: sd1s4: start 1, end = 2045651, size 2045651 > Mar 31 12:42:50 grunt /kernel: sd1s4: C/H/S end 933/6/34 (222291) != end 2045651: invalid (+++) > Mar 31 12:42:51 grunt /kernel: sd1: rejecting partition in BSD label: it isn't entirely within the slice (**) > Mar 31 12:42:51 grunt /kernel: sd1: start 1, end 2045651, size 2045651 > Mar 31 12:42:51 grunt /kernel: sd1d: start 0, end 2056007, size 2056008 (x2) (**) above is the same 'd' partition problem as above, and I cannot get rid of it either for the same reasons. (+++) is wierd. Ths is a 1GB SCSI disk, and the variable (or whatever) used to hold the number of tracks seems a little messed up.
