What I did: 1.- boot old kernel, unloading geom_mirror first 2.- mount & dump all fs's (easy enough thanks to gmirror's metadata being on the last sector) 3.- manually clear gmirror's metadata with dd 4.- repartition drives and setup gmirror again I'm attaching the conflicting configuration (two mirrors on two slices, the failing one without being bsdlabel'd). qvb -- pica --=-egYv+1O8CoMqPRQkKwiE Content-Disposition: attachment; filename=fdisk.ad4.txt Content-Type: text/plain; name=fdisk.ad4.txt; charset=iso8859-15 Content-Transfer-Encoding: 7bit ******* Working on device /dev/ad4 ******* parameters extracted from in-core disklabel are: cylinders=484521 heads=16 sectors/track=63 (1008 blks/cyl) Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=484521 heads=16 sectors/track=63 (1008 blks/cyl) Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information from DOS bootblock is: The data for partition 1 is: sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD) start 63, size 123715809 (60408 Meg), flag 80 (active) beg: cyl 0/ head 1/ sector 1; end: cyl 1023/ head 243/ sector 63 The data for partition 2 is: sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD) start 123715872, size 307195623 (149997 Meg), flag 0 beg: cyl 1023/ head 255/ sector 63; end: cyl 1023/ head 254/ sector 63 The data for partition 3 is: <UNUSED> The data for partition 4 is: <UNUSED> --=-egYv+1O8CoMqPRQkKwiE Content-Disposition: attachment; filename=bsdlabel.ad4s1.txt Content-Type: text/plain; name=bsdlabel.ad4s1.txt; charset=iso8859-15 Content-Transfer-Encoding: 7bit # /dev/ad4s1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 1048576 0 4.2BSD 0 0 0 c: 123715809 0 unused 0 0 # "raw" part, don't edit d: 1048576 1048576 4.2BSD 0 0 0 e: 10485760 2097152 4.2BSD 0 0 0 f: 2097152 12582912 4.2BSD 0 0 0 g: 4194304 14680064 4.2BSD 0 0 0 h: 104841440 18874368 4.2BSD 0 0 0 --=-egYv+1O8CoMqPRQkKwiE Content-Disposition: attachment; filename=bsdlabel.ad4s2.txt Content-Type: text/plain; name=bsdlabel.ad4s2.txt; charset=iso8859-15 Content-Transfer-Encoding: 7bit # /dev/ad4s2: 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 307195623 0 unused 0 0 # "raw" part, don't edit --=-egYv+1O8CoMqPRQkKwiE Content-Disposition: attachment; filename=gmirror_list.out Content-Type: text/plain; name=gmirror_list.out; charset=iso8859-15 Content-Transfer-Encoding: 7bit Geom name: gm0s1 State: COMPLETE Components: 2 Balance: round-robin Slice: 4096 Flags: NONE GenID: 0 SyncID: 1 ID: 2494591388 Providers: 1.
