I installed Solaris 10 x86 on an HP DL 360G5 with an HP smart array P400i controller. Two mirrored RAID volumes were created, each with it’s own spare.

I installed Solaris onto a ZFS partition during setup onto one of the mirrored volumes. Used the second mirrored volume to create another ZFS pool.

I patched the OS, rebooted, then ran zpool upgrade followed by zfs upgrade and rebooted again. This time, the boot partition was gone and I was left at the grub prompt.

You needed to upgrade grub to a version that supports the zpool/zfs version.
Otherwise, grub could not properly mount the root file system.

I reinstalled the OS, patched, rebooted, and ran zpool upgrade and rebooted fine. I was able to import the other zfs pool (on the second mirrored volume) – now that one is running zfs v4 and the root partition is running zfs v3, but I’m reluctant to try and upgrade it again....

        • Is this a supported hardware/software configuration?
        • Has anybody seen this before?

Thanks,
Neil
