I got a new harddisk for my laptop, attached it via firewire, used "dump
0aLf - / | restore xf -" (from the FAQ), and swapped it with my internal
one. During that, I also migrated /var and /usr to separate bsdlabels.
On reboot during fsck (ad0s1f), I got:
CANNOT READ BLK: 251403296
CONTINUE? [yn] y
THE FOLLOWING DISK SECTORS COULD NOT BE READ: 251403296, 251403297,
251403298, 251403299,
LOOK FOR ALTERNATE SUPERBLOCKS? yes
32 is not a file system superblock
SEARCH FOR ALTERNATE SUPER-BLOCK FAILED. YOU MUST USE THE
Is there a problem with the harddisk? Did I do anything wrong? How do I
find out?
Since I never used bsdlabel and newfs by hand before for more than
trivial cases, I might very well have messed something up. Here is what
I came up with.
Since I forgot to change it before swapping harddisks, I came up with
this simple fstab:
/dev/ad0s1b none swap sw 0 0
/dev/ad0s1a / ufs rw 1 1
/dev/ad0s1e /var ufs rw 1 2
/dev/ad0s1f /usr ufs rw 1 2
This is my bsdlabel for ad0s1:
# /dev/ad0s1:
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
a: 2097152 16 4.2BSD 2048 16384 28552
b: 4194304 2097168 swap
c: 314568702 0 unused 0 0 # "raw" part,
don't edit
e: 16777216 6291472 4.2BSD 2048 16384 28552
f: 251658240 23068688 4.2BSD 2048 16384 28552
g: 33554432 274726928 unused 0 0
h: 6287342 308281360 unused 0 0
This is the fdisk partition ad0s1:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
start 63, size 314568702 (153597 Meg), flag 80 (active)
beg: cyl 0/ head 1/ sector 1;
end: cyl 124/ head 254/ sector 63
Anything else? (I could probably recall most of the commands I issued.)
Thanks in advance for any help,
Jan Henrik
