I have two disks, ad0 and ad8.
ad0s1 and ad8s1 are a gmirror
ad0s2 and ad8s2 are in a zpool
Other than pulling ad0 and rebooting, is there a set of steps I can take
to make sure ad8 is bootable? Is an identical MBR a good enough test?
dd if=/dev/ad8 of=ad8.mbr bs=512 count=1
dd if=/dev/ad0 of=ad0.mbr bs=512 count=1
and here are the md5's of the MBR files
MD5 (ad0.mbr) = f7dced6b4ab7f171cc66ae44ece16a73
MD5 (ad8.mbr) = f7dced6b4ab7f171cc66ae44ece16a73
I want to check some production boxes to make sure they are set up
correctly. I've never had a problem with using whole disks in gmirror,
but I am new to using gmirror for slices.
Disk setup:
> gmirror status
Name Status Components
mirror/gm0s1 COMPLETE ad0s1
ad8
> zpool status
pool: tank
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
tank ONLINE 0 0 0
mirror ONLINE 0 0 0
ad0s2 ONLINE 0 0 0
ad8s2 ONLINE 0 0 0
