[OpenIndiana-discuss] OI boot problem

[Matt Connolly]

On my system, I see:

matt at vault:/opensolaris/boot/grub$ ls /rpool/boot/grub/
bootsign       capability     menu.lst       splash.xpm.gz

and 

matt at vault:/opensolaris/boot/grub$ ls /boot/grub/
bin                e2fs_stage1_5      install_menu       menu.lst           pxegrub            stage1             ufs_stage1_5       xfs_stage1_5
capability         fat_stage1_5       iso9660_stage1_5   minix_stage1_5     reiserfs_stage1_5  stage2             ufs2_stage1_5      zfs_stage1_5
default            ffs_stage1_5       jfs_stage1_5       nbgrub             splash.xpm.gz      stage2_eltorito    vstafs_stage1_5

There's definitely more files in /boot/grub in the active boot environment than there is in /rpool/boot/grub.

Perhaps you can boot off the live disc, and

# installgrub PATH/boot/grub/stage1 PATH/boot/grub/stage2 /dev/rdsk/c0t1d0s0

exchanging PATH for the mount path to what was the active boot environment, not just the root of the pool.

I checked on my machine if I `beadm mount be_name mount_point` then in `/mount_point/boot/grub/' I see the full list of boot files.

The only thing I'm not sure about is how `beadm mount` goes at mounting boot environments from another pool.


Hope that helps somewhat,

Matt

All seemed good though I didn't fully check that the mirror booted (silly me etc. - this is a home PC). Then the worst happened and the new drive where OI was installed failed. So I'm left with the drive carrying the mirror that doesn't boot (currently the only drive in the machine). Is this recoverable - or is it goodbye to OI ?
