Current Grub2 & problem with /boot on different drive

Current Grub2 & problem with /boot on different drive

[Dean Loros]

Greetings--

Ubuntu has been testing Grub2 for a number of months now & a
"interesting" problem has surfaced. If your /boot is on a different
drive than the MBR, you will have several minutes of drive use before
you get to the Grub2 menu. My current timing is 3min 50sec to menu--this
is with a i7-920 system with four internal drives--all SATA-II. My first
bug report on Launchpad was dated 8-28-2009 & this had started a few
days earlier. Before that date, Grub2 would take only 3~5 seconds to get
to menu. Updates after this have not cured this issue. The current
"work-around" in the bug report is to re-set MBR & /boot to the first
drive. This problem only shows up in multi-boot/multi-drive systems.

During the 3+ minutes, there is constant drive activity. Colin had asked
at one time for me to do a debug run which was one of the most painful
times I have had in current memory--the system worked for more than
20min without going to menu & required booting with a LiveCD to repair
problems from the outside.

It looks like Grub2 needs to scan all the drives for all the supported
filesystems several times before it "finds" the /boot that works. I will
also note that I do not have any other grub installs other than my main
Grub2 install, so there is only one /boot in the system. MBR is on SDA
(storage drive)--I also have one install on SDB, my /boot is on SDC with
a second install & two more operating systems are on SDD for a total of
five operating systems (Two testing Karmic & several other installs).

My thought is: Is there a way to "tag" the Grub2 /boot so time to locate
is acceptable? Or is there another way to scan filesystems? Maybe a way
to "tag" the type of filesystem in use?

Bug report is: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/420933
With supporting information. IF you need more information or want me to
do further testing, please contact me @ ubuntu1user at gmail.com


Thank you for your time in this matter.

We have theoretically discussed this problem with Robert but weren't
sure if instances of it exist. The problem is that (UUID=..) syntax
rescans all drives on every access. We devised a solution to split
search.mod into search_uuid.mod, search_file.mod and so on but we agreed
that it will be done after 1.97 due to amount of changes it requires.
I'm ok to implement it, it's not much work but I can't make any promises
about my current disponibility.
As a workaround for time being you can use one or more of the following:
1) Increase cache size. Can this be done in 1.97?
Change include/grub/disk.h and replace
#define GRUB_DISK_CACHE_NUM     1021
with a bigger number
2) Modify scripts to hardcode boot device and not use UUID. If you
change disk order it will result in boot failure but it may be a local
workaround
3) add search -s -u <UUID> as first command of your grub.cfg

Hi Vladimir--

I have tried option #3 & have a question about syntax--should it be just search -s -u UUID number or should the number be in <> ?

I tried without the <> & grub took the same ammount of time as before--I have edited grub.cfg with the <>, but have not rebooted with it in that form until I hear from you on this.

Thanks!!!!

I'm a little baffled. Why does the disk cache size make a difference
here? He has four disks - I'd have thought that 1021 would be plenty.

1021 is the number of cached 4KiB blocks and is used in hash
calculations. If he has a lot of cache misses it will result in long
boot times

It's without <>. Well I extected it to have only partial effect since
grub.cfg is parsed quite lately

Do you have a recommendation for a new value? I can build a test package
and ask Dean to try it out.

Greetings--

Well Vladimir, the modification to grub.cfg makes a 20sec
difference--times went from 3 min 50 sec to 3 min 30 sec--better, but
still a "bit" long :)  So I would say that option #3 has very little
effect & I really do not want to hardcode as per option #2....I am open
to "interesting" mods to bring the time down to "normal" levels & It
looks like Colin is willing to do some package building in between his
busy workweek. So what are your thoughts as how this can be approached?

Greetings Colin & Vladimir--
Tried the patched grub2--I've gone back to the 3 1/2 minutes to menu
with it--before it was 3 min 50 sec--so it is a slight improvement--any
other ideas?

Cheers!!!

Can you issue "set" from grub console. Are you sure you really use my
version?

Re: Current Grub2 & problem with /boot on different drive

[Dean Loros]

I have installed the patched Grub2 that Colin has in his PPA & done the
normal updating that he requested including confirming that it is
installed to my first drive. It is the only grub installed on my system,
so I feel very certain that I was using it during my timed run last
evening. To re-confirm:

dean@linux:~/Desktop$ sudo grub-install /dev/sda
Installation finished. No error reported.
This is the contents of the device map /boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

(hd0)    /dev/sda
(hd1)    /dev/sdb
(hd2)    /dev/sdc
(hd3)    /dev/sdd
dean@linux:~/Desktop$ grub-install -v
grub-install (GNU GRUB 1.97~beta3)

Is there anything else you want me to check?

Cheers!!!
Dean

I have looked as far as I can via Google to try to get into a terminal
similar to how things were done in grub. There is little to no
information available--I was very fluent in how to do things with
grub--I am at a loss as to achieve this in grub2.

Vladimir means to press `c' when the menu gets shown and to type `set'
and then tell us the output.

Re: Current Grub2 & problem with /boot on different drive

[Dean Loros]

Thank You Felix!!! That was the information I lacked!!! Sorry all about the prior overly-general subject

Information for Vladimir & Colin:

Results of set:

sh:grub> set
?=0
color_highlight=magenta/black       *(custom colour to match grub image)*
color_normal=red/black       *(same comment)*
default=0
gfxmode=640x480
pager=
prefix=(UUID=fc1446a5-94e9-40f8-9ebb-2442107fc13c)/boot/grub
root=hd2,2

I can verify that I am using Colin's PPA versions of grub2, grub-pc &
grub-common.
Time to menu is constant @ 3 1/2 minutes--there is a additional 30sec
after the booting kernel is selected.
