[indiana-discuss] "zio_read_data failed" in GRUB while trying to boot from compact flash (CF)

[James Lee]

I am trying to get OpenSolaris 2009.06 to run from my 32 GB Kingston
compact flash drive attached to a standard Sil 0680 IDE controller.  The
installer detects the card and install successfully.  Upon reboot, GRUB
drops to a "grub>" prompt.  Any attempts to read menu.lst fail with:

grub> root (hd0,0,a)
Filesystem type is zfs ...
grub> find /rpool/boot/grub/menu.lst
zio_read_data failed
Error 15: File not found


However, I have no problem importing/mounting rpool from the livecd and
it scrubs fine:

> # zpool status
>   pool: rpool
>  state: ONLINE
>  scrub: scrub completed after 0h20m with 0 errors on Thu Jun  4 03:48:38 2009

Here's the zdb output if it helps:

Any idea why this would fail in GRUB but work when booted from a livecd?
 Thanks.
