Is there a decent walkthrough anywhere on the Net for using
disklabel, fdisk , etc - along with an explanation of what a,c etc all
mean?
man disklabel etc all assume you know what those letters mean.
I know c is the whole partition, but that's it.
I need to know because:
<PHYSICAL><-----EXTENDED-----><------PHYSICAL------------>
ad0s1 ad0s5 ad0s6 ad0s3
<-winXX--><-msdos-><Slackware><-------BSD---------------->
| 2Gb | 1.5Gb | 2Gb | / | swap | /usr | /var |
^
|
I have an old Slackware partition
that has FUBARed itself so throuoghly that it can't even be mounted.
(Actually there were about 3 partitions in there, but they're lost now)
It's in the second logical partition in an extended DOS partition on
my second physical partition (dev/ad0s6 in FreeBSD)
There's a Gb of data in ad0s5 (which is fine).
BSD dumps ad0s6 altogether when it boots; and fdisk from a
boot CD says something along the lines of:
"Second slice extended past end of disk" or similar
(box is offline today, so I can't check right now)
This concerns me; if I try to fdisk/newfs ad0s2 (assuming I
could see it), I risk losing ad0s3, which is the only bit of the disk
I really want to keep.
I assume/hope that if I blow away the extended partition
entirely, I can just recreate it.
But I don't really know what it's called?
Is it ad0s2?
And won't I need to let BSD know where / has moved to?
What I'd really like is some advice from anyone who knows this stuff.
But I'm surprised the Handbook doesn't go into a lot of detail on this,
since dual-boot systems are fairly common amongst cheapskates like me.
If I can free up that 2Gb, maybe I'll have space for the docproj port... :)
