[gentoo-user] Grub2 takes very long to make config or install

[gentoo-user] Grub2 takes very long to make config or install

[Matthias Fechner]

Hi,

I followed now the wiki page:
http://en.gentoo-wiki.com/wiki/Grub2

At the step to create the config file with:
grub-mkconfig -o /boot/grub/grub.cfg

and install grub2 with:
grub-install /dev/sda

it needs several hours to complete each of the commands. Is this normal?

Bye,
Matthias

No.




Sorry, I have no idea why this happens. I used grub only once, but at 
least I know it it did not take hours, it was about 1-2 seconds, or maybe 
even less, I did not stop the time :)
Is there something in syslog when you run this, or are the -v arguments 
that would make the process more verbose?

The old grub sometimes paused for around a minute because it searched for 
the floppy, the --no-floppy switch speeded this up.

hm, that is a really good point, I found in dmesg in in the logfile, 
tones of the following lines:
Jun 24 06:54:42 idefix-pc kernel: end_request: I/O error, dev fd0, sector 0
Jun 24 06:54:54 idefix-pc kernel: end_request: I/O error, dev fd0, sector 0
Jun 24 06:55:06 idefix-pc kernel: end_request: I/O error, dev fd0, sector 0
Jun 24 06:55:19 idefix-pc kernel: end_request: I/O error, dev fd0, sector 0
Jun 24 06:55:19 idefix-pc kernel: Buffer I/O error on device fd0, 
logical block 0

So it searches on the floppy and seems not to stop here after many hours 
passed.

Regarding the grub-mkconfig man page there is no option available to 
skip floppy check.
I will try at home if I can speed up the installation procedure with 
--no-floppy.

Thanks for the tip.

Bye,
Matthias

it seems to be a small bug in grub2. The installation needs several 
hours but works perfectly and it is a step done only once.

Matthias
