zfs discuss - Nov 2008 - How to deal with "ended in grub> prompt" issue ?

Caimaniacs,

we are currently seeing bunch of bugs reporting
problem when people end up in ''grub>'' prompt
after the installation of recent OpenSolaris
build (101a).

The root cause of this problem hasn''t been
identified yet and there are more possibilities
what might be happening here.

So far it seems that at least some of them are related
to ZFS in some way - those cases could be easily
identified, as there is straightforward workaround
to make GRUB find menu.lst file.

P1 bug was filed to track this in ''solaris/kernel/zfs''
category:

6769487 Ended up in ''grub>'' prompt after installation of
OpenSolaris
2008.11 (build 101a)

When new bug is reported complaining about ending up
in ''grub>'', please don''t close the bug as
duplicate without
appropriate evaluation done, as there are more ways how one
could end up in GRUB prompt and we might be missing
other issues which are not related to 6769487
(e.g. when /rpool/boot/grub/menu.lst file was not created).

Thank you,
Jan


How to triage:
--------------

* In all cases, ask reporter to attach /tmp/install_log file

With LiveCD, this can be obtained using following procedure:
[1] Boot LiveCD
[2] From terminal window:

$ pfexec su -
# zpool import -f rpool
# beadm mount opensolaris /a

install_log file is located in /a/var/sadm/system/logs/install_log

* Ask reporter to verify if workaround for 6769487 works in reported
  case (workaround was actually applied in previous step).

[1] boot LiveCD
[2] Open terminal window and import ''rpool''

$ pfexec su -
# zpool import -f rpool

[3] Reboot from hard drive and verify if workaround
was successful.

* If workaround worked, the bug might be closed as ''tracked in
bugster''
In that case, please put also following text in Whiteboard:
BugsterCR=6769487

* If workaround didn''t work, additional evaluation will have
  to be done, as issue reported is probably not related to 6769487.
