(solved) grub does not recognize the hard disks and partitions

Hello everyone . there are four hard disks installed : 1 ) / dev / sda ( divided into / dev / sda1 - Windows7 , / dev / sda2 - Linux ( / ) , / dev / sda3 - Linux ( / home ) ) 2 ) / dev / sdb ( divided into / dev / sdb1 ( / ) - arch linux , / dev / sdb2 - home of arch linux ( / home ) , / dev / sdb3 swap ) , 3 ) / dev / sdc ( divided into / dev /sdc1- linux ( / ) , / dev / sdc2 - linux ( / home ) ) , and 4 ) / dev / sdd ( divided into / dev / sdd1 - linux ( / ) and / dev / sdd2 linux ( / home ) .

The other disks , / dev / sde and / dev / sdf are external usb hd .
the problem is that  the grub of the arch linux (that is installed on /dev/sdb) is confusing everything . the partitions related to the hard disk / dev / sdb sometimes appear as / dev / sda and / dev / sda as / dev / sdb . sometimes the grub recognizes the swap partition ( which in reality is in / dev / sdb3 ) as if it were in / dev / sdc3 . so if I try to start the system and enter the Graphical on arch linux it is warned that there is no / home ( or not found ) .it seems that this happening as a result of the mess grub is doing .

This all started after / dev / sdd was installed (the fourth hard disk) . I went in the bios and set the / dev / sdb as the high-priority on startup. I did so because the arch linux is installed on /dev/sdb . at other times everything seems ok. but recently I made a whole system updating and after I rebooted all was messy again.

below how is the system with the four hard disks:

Re: (solved) grub does not recognize the hard disks and partitions

You may want to read this article on persistent device naming

I recommend the section on by-UUID

Re: (solved) grub does not recognize the hard disks and partitions

Try using UUIDs (or PARTUUIDs) instead of /dev/sd<x> in grub.cfg, perhaps?

thanks. the /etc/fstab file is like below. I think I have to fix it:

This is not the root of the problem:

Persistent naming via file system UUIDs are used by default in GRUB.

It's the fstab.
Here is an example of fstab using UUIDS.

Re: (solved) grub does not recognize the hard disks and partitions

I have fixed /etc/fstab but it is no use! In fact, now I can access  /dev/sdc1, /dev/sdc2, /dev/sdd1, /dev/sdd2, /dev/sde and /dev/sdf. But after I have rebooted I have realized that fixing /etc/fstab revealed to have been useless.
I still cannot access /dev/sda1 (windows) as well /dev/sdb1 and /dev/sdb2 (where arch linux is installed).
If I try to execute #grub-mkconfig -o /boot/grub/grub.cfg agian there is another mess and I cannot access any partition anymore.
Shoud I edit /boot/grub/grub.cfg? Another doubt: why /etc/grub.d/40_custom is empty. I cannot edit it.
To make things worse, the /boot/grub/menu.lst does not exist anymore...
thanks for your attention.

Re: (solved) grub does not recognize the hard disks and partitions

If I were you I'd try the simplest method first

The simplest way to fix this would be to boot from the install disk mount all your partitions and turn your swap on
then delete the current fstab contents  and regenerate fstab like we do in

https://wiki.archlinux.org/index.php/Be … e_an_fstab

genfstab -U -p /mnt >> /mnt/etc/fstab

If you have already done that or it doesn't do it I'd personally go straight to  GPT UUID aka PARTUUID
I have had normal UUID that didn't do it for me before. If PARTUUID doesn't do it then for me it hasn't been a fstab issue.

I usually just take and do a

blkid >> /mnt/etc/fstab

to get the info into the fstab then its just cut and paste see the example on the wiki

https://wiki.archlinux.org/index.php/fstab#GPT_UUIDs

If this doesn't do it I'd check to see you have all your mkinitcpio.conf hooks and modules (lvm2,raid,etc) installed made and configured properly

https://wiki.archlinux.org/index.php/Mkinitcpio
https://wiki.archlinux.org/index.php/Lvm
https://wiki.archlinux.org/index.php/RAID

Luck

Re: (solved) grub does not recognize the hard disks and partitions

Thanks you so much, dlm1065. Sorry but I still have a doubt: how the command "genfstab -U -p /mnt >> /mnt/etc/fstab" will regenerate the fstab file for the archlinux which is on the partition /dev/sdb1 if I have booted using the install disk to mount my partitions on /mnt?

Re: (solved) grub does not recognize the hard disks and partitions

Missed you post sorry its taken me so long to reply.
The whole purpose of genfstab is to create an fstab it takes the list of what is mounted and creates the fstab in the folder it is directed to.

Since you did not say that you had done any raid or LVM nor anything about UEFI I am assuming you are doing a simple set of mounts?  In your first post you said that

 / dev / sda1 - Windows7 ,
 / dev / sda2 - Linux ( / ) ,
 / dev / sda3 - Linux ( / home )
 / dev / sdb1 ( / arch ) 
 / dev / sdb2 - /home of arch linux 
 / dev / sdb3 swap 
 / dev /sdc1- linux ( / ) ,
 / dev / sdc2 - linux ( / home )
 / dev / sdd1 - linux ( / ) 
 / dev / sdd2 linux ( / home ) .

**warning:do fdisk to be sure these are still the correct partition names I can't be responsible if you use the wrong partition** If they are still the same, just try doing

mkswap /dev/sdb3
swapon /dev/sdb3
mount /dev/sda2 /mnt
mkdir /mnt/home
mount /dev/sda3 /mnt/home
mkdir /mnt/windows
mount -t ntfs-3g /dev/sda1 /mnt/windows
genfstab -U -p /mnt >> /mnt/etc/fstab

Re: (solved) grub does not recognize the hard disks and partitions

thank you so much for you attention dlm1065.

1)Unfortunately, it is no use. For some reason that I cannot identify arch linux (installed in /dev/sdb1 (/) and /dev/sdb2 (/home)), after the installation of /dev/sdd (the fourth hard disk), recognizes the partitions that are in /dev/sdc (the third hard disk) as if they were in /dev/sda. And so, after this first change, it also changes  the recognition of the partitiond that are in /dev/sda (the real one) as if they were in /dev/sdb and the recognition of the partitions of /dev/sdb as if they were in /dev/sdc. And even if I start the using the installation disk it is the same situation. So, for example, the real swap partition is /dev/sdb3 but it is recognized as if it were in /dev/sdc3.

2)Another thing: the genfstab command returns an error message which says the genfstab command does not exist (or is found).

3)Another thing I think it is important to remark: I have other distros installed in /dev/sda2; /dev/sdc1 and /dev/sdd2 (slack linux) and in these partitions the recognition of the partitions and of the disks are perfect, no problema at all. I mean, /dev/sda is recognized as /dev/sda with its correctely partitions and so on.

4) I can even manage to fix grub by using chroot + grub.mkconfig + grub-install. But it does not solve the question because when I enter the grub menu and choose arch linux the mess comes again and I cannot login. I can see that during the initialization of arch linux  the first hard diks that appears is /dev/sdc and after that there is the described hard disk mess and I cannot login. So I cannot run arch linux any more

5)If I enter the console mode in arch linux and try #grub-mkconfig the partitions are recognized in the wrong hard disks like I have described (except /dev/sdd. this is the only hard disk and partitions arch linux recognizes correctly)

Re: (solved) grub does not recognize the hard disks and partitions

As a sanity check, could you post the output of ls -l /dev/disk/by-uuid  ?

Re: (solved) grub does not recognize the hard disks and partitions

Okay, what I was checking for was whether you had somehow managed to replicate UUID's.  It is possible if you start cloning volumes.   You do not have this problem.

So, the good news is that you UUIDs are correct.   One can assume that the /dev/sdXY  assignments are arbitrary, non-deterministic and capricious.  The UUIDs are "Right".  The random assignments of /dev/sdX are what are "Wrong".  Do not count on the later.  Use nothing but UUIDs in both the boot loader and fstab.   

I realize you have been trying various combinations, but please, share your present grub  configuration and fstab.

Re: (solved) grub does not recognize the hard disks and partitions

1) here is the /etc/fstab:

2) and the /boot/grub/grub.cfg is like below - I shall warn you that I have edited it manually and tried to associate the partitions to the right hard disks but it did not work either (when I try to initialize still the partitions associated to the wrong hard disk and arch linux does not initialize):

3)also, trying to find a solution, I edited /etc/grub.d/40_custom file and entered some information, but it did not work either. the file, after I have edited it was like below:

GNU nano 2.3.6                                                 File: /mnt/arch/etc/grub.d/40_custom

3)I have noticed that besides the /boot/grub/grub.cfg file there is also a /boot/grub/grub.cfg.new file and it is like this (you can notice that I have not edited this file and the partitions are in the wrong hard disk):

Re: (solved) grub does not recognize the hard disks and partitions

I thank you guys for your attention and help. The issue has been finally solved. Before the final solution I changed the position of the hard disks connections to the mother board. but the arch system still recognized  the hd and the partitions /dev/sdb as /dev/sdc. The only it recognizes correctly is in case there are only 2 hd: /dev/sda and /dev/sdb. If I install the 4 hd the arch system recognize the partitions and hd wrongly.

However, in the end I tried to change the options of the fstab file to defaults and also to comment the entries that refer to the usb external hd. and voilá. the solutions was easier than I had expected. now I can initialize arch system. I must remark that arch system still recognizes /dev/sdb as /dev/sdc but it does not prevent the arch system to initialize.

maybe because I am not using arch grub anymore. now I am using another distro grub (the distro that is in /dev/sda2).

1) this the /etc/fstab by which I could not initialize the arch system

# /etc/fstab: static file system information
    #
    # <file system> <dir>   <type>  <options>       <dump>  <pass>

2) this the /etc/fstab by wichi I can initialize the arch system (even though it sitll recognizes /dev/sdb as /dev/sdc). I changed the options to defaults and commented the usb external hd entries...

I do not know if I use again the arch grub again, applying the changes to the arch grub, the system will initialize too...I have to try it...
