How can I fix this safely? To: FreeBSD-questions@FreeBSD.org MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG 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. 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. Thanks for the help. __________________________________________________ Do You Yahoo!? Yahoo!
