I posted this to questions but no replys (yet), so I'll ask here. Necessary info: 4.2-STABLE FreeBSD 4x20GB drives on two Promise controllers: ad4, ad6, ad8, ad10. Now my issue. I have these 4 20GB drives in a RAID 10 Vinum configuration. (40GB total usable drive space). Of the 40GB total, I still have about 15GB unused. I want to create some partitions and ultimately make this free space usable with vinum. The problem I have is that I discovered that my disklabel for ad4 and ad6 isn't the same as disklabel -r for these drives. In particular I have 'amnesiac' disks. Here is disklabel for ad4: su-2.03# disklabel ad4 # /dev/ad4: type: unknown disk: amnesiac label: fictitious ... ... 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 40088160 0 unused 0 0 # (Cyl. 0 - 63631) Now here is the disklabel -r for ad4: su-2.03# disklabel -r ad4 # /dev/ad4: type: ESDI disk: ad4s1 label: ... ... # size offset fstype [fsize bsize bps/cpg] a: 253952 0 4.2BSD 0 0 0 # (Cyl. 0 - 403*) c: 40088160 0 unused 0 0 # (Cyl. 0 - 63631) e: 23552000 253952 vinum # (Cyl. 403*- 37787*) Ad6 is similar. I guess I can sum it up by saying my drives have not been labeled. This may sound silly, but how serious is having an amnesiac disk? I've been running this machine for months. Have I been skating on thin ice and not knowing it? How can I fix it without doing any damage to my installation. The manpage talks about writing a disklable as clobbering my existing drives. Say it ain't so. While I'm at it, any tips or pointers on the best way to create a partition in the free space in the drives. Thanks for the help.
