Hi I have a server with 2 hard disk in mirror setup.
My slices are:
Code:
root@spam:/boot # gpart show ada1
34 976773101 ada1 GPT (466G)
34 6 - free - (3.0K)
40 128 1 freebsd-boot (64K)
168 2097152 2 freebsd-ufs (1.0G)
2097320 16777216 3 freebsd-ufs (8.0G)
18874536 16777216 4 freebsd-ufs (8.0G)
35651752 1048576 5 freebsd-ufs (512M)
36700328 1048576 6 freebsd-swap (512M)
37748904 939024231 - free - (448G)
My mirror has ada0 ada1, ada0 var slice fails, them I decide to replace the
whole disk and follow the instructions for that using gpart and backup my
current good disk layout into my new disk.
gpart backup ada1 | gpart restore -F /dev/ada0
This create my slices, I forget each mirror slice and add each slice into
the mirror again.
Everything working, but looks like I forget to add the bootcode to my new
disk because it won't boot.
Now is booting from 2nd disk but need to boot from all hard disk, if ada1
fails I will have issues.
If some one could explain me the steps will be appreciated, thanks.
