[OpenIndiana-discuss] Installing grub on a zfs mirror rpool

Sat, 20 Feb 2021 15:09:36 -0800 


My HP Z400 based Solaris 10 u8 system had some sort of disk system fault.  It 
has a 100 GB 3 way mirror in s0 for rpool and the rest of each  2 TB disk in s1 
forming a RAIDZ1.

After reseating all the cables I was able to boot to a single user shell using 
the installation DVD and scrub both pools with no errors reported, though a 
small part of the rpool mirror was resilvered.

However, I can't get the system to boot from the hard drives. I've tried using 
installgrub but had no success.

What are the correct stage1 and stage2 files to use for a zfs mirrored root 
pool?  Should I install grub on all 3 disks?

The presence of zfs_stage1_5 makes it very ambiguous.  I can find no 
explanation of what that is for.

I've continued to use u8 because I prefer using twm and I've never figured out 
how to make OI do that. This system does not have internet access and is set up 
for software development and scientific work.  All of the systems are connected 
to an 8 port KVM switch.

I use OI for my internet access and Windows 7 Pro and Debian 9.3 on a 3rd 
system to run electronics engineering codes which are not available for any 
other platforms.  I tried using VirtualBox for Windows on OI, but it was 
intolerably slow.
