Perhaps I was being too clever trying to setup a swap partition,
beacuse If I change my label so that vinum part is idential to
the "unused" part (but assigned to a:) it works. *puzzles*

| following steps:
|
| # dd if=/dev/zero of=/dev/ad2 bs=1k count=1
| # fdisk -BI ad2
| # disklabel -B -w -r ad2s1 auto
|
| And at this point, I use the following to extract the current
| label, and then I edit it with vi, and then update it:
|
| # disklabel ad2s1 > label
| # vim label
| # disklabel -R -r ad2s1 label
|
| Following is the tail end of the label (I don't edit anything else)
| where I add 'swap' and 'vinum' partitions:
|
| a: 4193280 0 swap
| c: 156301425 0 unused 0 0
| e: 152107200 4193280 vinum
|
| The results, when "restoring" the label, however, are inconsistent,
with
|
| # disklabel ad2s1
| # disklabel ad2
| # disklabel -r ad2s1
| # disklabel -r ad2
| # disklabel /dev/ad2s1
| # disklabel -r /dev/ad2s1
|
| the results are expected (and identical):
|
| <snip/>
|
| 8 partitions:
| # size offset fstype [fsize bsize bps/cpg]
| a: 4193280 0 swap # (Cyl. 0 - 4159)
| c: 156301425 0 unused 0 0 # (Cyl. 0 - 155060*)
| e: 152107200 4193280 vinum # (Cyl. 4160 - 155059)
|
| However, for the other two permutations... the results are different:
|
| # disklabel /dev/ad2
|
| <snip/>
|
| 8 partitions:
| # size offset fstype [fsize bsize bps/cpg]
| c: 156301488 0 unused 0 0 # (Cyl. 0 - 155060)
|
| # disklabel -r /dev/ad2
| disklabel: bad pack magic number (label is damaged, or pack is unlabeled)
|
| At this point, I use the following vinum configuration file to
| setup vinum "vinum create -f vinum.conf"
|
| drive d2 device /dev/ad2s1e
| volume tmp setupstate
| plex name tmp.2 org concat
| sd length 2000m drive d2
|
| And this produces...
|
| 1 drives:
| D d2 State: referenced Device Avail: 0/0 MB
|
| 1 volumes:
| V tmp State: down Plexes: 1 Size: 2000 MB
|
| 1 plexes:
| P tmp.2 C State: faulty Subdisks: 1 Size: 2000 MB
|
| 1 subdisks:
| S tmp.2.s0 State: crashed PO: 0 B Size: 2000 MB
|
|
| And of course, this is where I get stuck... With 4.6 I didn't have any
| of these problems (from the bad pack magic number to the missing device
| in the vinum state). Anyway, following is the full output from the
| disklabel.
|
| # disklabel -r /dev/ad2s1
| # /dev/ad2s1:
| type: unknown
| disk: amnesiac
| label:
| flags:
| bytes/sector: 512

| e: 152107200 4193280 vinum # (Cyl. 4160 - 155059)
