All in all, your partition table seems to be gone. If you created
it on
gmirror before (gm0s1) you may still have the same partition table on
the other half of the mirror. You can try to move it to ad6 with
bsdlabel and verify if you can see file system inside partitions.
Okay, tried that now.. Saved ad0s1 label, reloaded it onto ad6s1..
Now I got same partition table on ad6s1 as on ad0s1...
Trying to mount any though gives me incorrect super block... fsck
cannot find any superblocks either..
So.. What to do now then? Just for get ad6 and start from scratch
from ad2? (as i said, the data isnt very old realy)...
Im thinking about doing complete reinstall on ad4+ad6 then.. Can I
do that? fdisk both with full partition on both, create a new
gmirror between ad6s1/ad4s1 (or should i go on ad4/ad6?), create
slices, use dump | restore (of course with apps shutdown so no data
is changed.. or at least nothing that I care about) to copy all
files from ad2 to new mirror.. what do I need to do more? bsdlabel -
B on both to write boot blocks? Is there anything else to think about?
Ok just for the record, I plugged both sata disks in, cleared them,
created a new mirror on both of them, sliced up and dump -0 -L -f - /
| restore -r -f - all filesystems, also bsdlabel -B. and what i
missed in the above thext, fdisk -B to write boot0 code.. Now its
booted fine on the mirror!
altough, one thing that I got curious about. In the fdisk manpage it
says -b can be used to change the bootcode.. and that default is /
boot/mbr.. What is this? I checked md5 against boot0 and its not the
same (altough I guess it might just be some boot0 with different
config..). I never found any references to this mbr file in neither
man pages or handbook.
Again, thanks for the help :)
