OK I reinstalled grub using installgrub from the livecd and it got a bootable system back. However as soon as I did anything with the zpool on the second partition I needed again to reinstall grub.
Then I started to populate the filesystems from a backup archive and this seemed to be corrupting things on the first ( Solaris ) partition as utilities in /usr/sbin started not being found, giving an error message of "Bad exchange descriptor" and now I have got the situation where executing some other commands (eg du ) gives the error "I/O error" so the disk appears to be getting more corrupted as I put things into the second zpool. Now I know I have done all this before with opensolaris on a normal disk so I assume all of this is due to the fact this is a solid state disk. T -- This message posted from opensolaris.org
