 Posted: Sat Sep 28, 2013 12:37 pm Post subject: Block device /dev/sdc3 is not a valid root device [solved] |
 |
|
Hello,
I'm trying to get my box work with ahci. I'm currently using sata drive "as ide", and everything is fine : the box does boot, and I have access to all the fs and the sata HDD, except the one hot-plug connected on a e-sata port.
The thing is that if I want hot-plug with that e-sata HDD, I've read that I do need to set up HDD management in the BIOS, as ahci.
My motherboard is Asus P5Q Pro : its bios offers to manage sata HDD as IDE, RAID or AHCI.
When I switch, there in the BIOS, HDD management on AHCI, my box doesn't boot anymore : neither Gentoo - I get the | Quote: | | !! Block device /dev/sdc3 is not a valid root device !! Could not find the root block device in |
message,
nor Windows 7 - I get | Quote: | | Error 13 : Invalid or unsupported executable format |
message.
So this leads me on the track of a Grub issue, rather that a Kernel issue. I've been reading closely the posts Block device /dev/sda3 is not a valid root device and Intel Corporation ICH9M/M-E SATA AHCI [SOLVED], that describe issues really close to mine, but following what's said in them didn't solve it.

Carlino,
Fixing Windows 7, adter it was installed in IDE mode, is a nest of vipers. I would like to fix my work laptop so I can use the eSATA port.
Nothing I've found on the internet works, short of reinstalling. I can't do that, its not my laptop.
If you do find an upgrade path for Windows 7, please share it.
Gentoo is much easier.
| Code: | | !! Block device /dev/sdc3 is not a valid root device !! Could not find the root block device in |
should contain a list of block devices the kernel can see. If the list is empty, it points to a kernel option missing.
| Code: | 00:1f.2 IDE interface: Intel Corporation 82801JI (ICH10 Family) 4 port SATA IDE Controller #1
00:1f.5 IDE interface: Intel Corporation 82801JI (ICH10 Family) 2 port SATA IDE Controller #2
03:00.0 IDE interface: Marvell Technology Group Ltd. 88SE6121 SATA II / PATA Controller (rev b2) |
Switch to AHCI mode in your BIOS, boot a liveCD/USB and see what lspci -k shows.
I would not be surprised to learn that
a) that the ICH10 does not use the ahci driver
b) you hard drives are reordered

I'm not sure to understand "b) you hard drives are reordered", unless it matches the fact that in the hard drive settings, in the bios, I've had to reorder the drives (P0, P1, P2), to make them coincide with what I declared in Grub. I first thought that was the reason why, it couldn't boot. But still, it doesn't boot.... so I probably miss a driver. Would you enlighten that part please ?
Besides, about Windows 7, striking the F8 keys to choose where to boot from, I gave a try to the HDD where I installed W7. And it did boot, smoothly, with no complain. I turned on my external e-sata HDD, W7 installed a driver, and I could access the drive.
That message, from grub Error 13 : Invalid or unsupported executable format would tend to let me think my drive aren't in te order Grub expect them to be....

Carlino,
This is interesting and correct
| Code: | 00:1f.2 SATA controller: Intel Corporation 82801JI (ICH10 Family) SATA AHCI Controller
Subsystem: ASUSTeK Computer Inc. P5Q Deluxe Motherboard
Kernel driver in use: ahci |
Whats more interesting is that the controller at | Code: | | 00:1f.5 IDE interface: Intel Corporation 82801JI (ICH10 Family) 2 port SATA IDE Controller #2 |
has vanished. That was there when you had the controller in IDE mode.
One of two things has happened. The drives on that controller are no longer acessable to the computer or your controller appears as two devices in IDE mode and only one in AHCI mode. IF the latter is true, your drives may well be reordered.
Grub is unhappy about
Boot to the grub menu, select an option and press 'e'
You can now edit the selected option in memory.
Change the root (hd0,0) to root (hd1,0) and allow the boot to continue. Repeat for other drives ... one should load the kernel but there will be other errors, as root=/dev/... is incorrect, so root won't mount.
When you fix that, /etc/fstab will be incorrect too, so root will stay read only.

NeddySeagoon,
Thanks for the advices : it now works like a charm. Actually I haven't had to change root (hd0,0) : root (hd1,0) already leads to the Windows 7 area. As you mentioned, I tried different fs, to find the valid root device, and it was /dev/sda3 that was expected. From there, being in a decent environment, i ran fdisk -l to find out how the HDD where seen, modified /etc/fstab and grub.conf in consequences.
It flows like a charm ; even Windows 7, without patching. Oh, and I now can access the e-sata HDD
