 Posted: Wed Jan 18, 2006 6:19 pm Post subject: System suddenly can't find SATA devices |
 |
|
Hi,
I rebooted this morning and found that all-of-a-sudden my the system couldn't mount any of my hard disk partitions.
The error is
| Quote: |
"no such file or directory...while trying to open /dev/sda1"
|
where /sda correspond to my SATA drive.
No 'sda*' devices exist in the /dev directory.
When I reboot from the Gentoo 2005.1 live cd, the '/dev' directory does have '/dev/sda*' devices. Thankfully I could mount my home directory and archive uncommitted code changes to another machine.
"What's changed?" I ask myself since I last rebooted a month ago.
a) I emerged GRUB
b) I created a symbolic link from one filesystem to another.
A former colleague told me that b) above could cause such a problem. I rebooted w/ the live cd, mounted the drive, removed the offending link, then rebooted from the hard drive. Same problem.
I then did a visual diff on the 'dmesg' outputs between the gentoo livecd boot and my hard disk boot.
It looks like the problem is that the system is putting the devices here:
| Quote: |
/dev/scsci/host1/bus0/target0/lun0/
|
as part1,part2,etc..
Instead of in /dev/ as sda1,sda2, etc.
I honestly don't know what's changed..
I also see this error in the dmesg further upstream in the 'hard disk' boot. I don't see it in the 'live cd' boot.

any insights?
thanks,

Ok. I got past this problem by replacing in my /etc/fstab all my
with
| Quote: |
/dev/scsci/host1/bus0/target0/lun0/part
|
Apparently updating udev caused this issue. I need further input on this. Plus more understanding of udev and what caused this.
Ok. at least I can go back to work.
thanks,

file under "D" for "D'oh" ...
it looks like the problem lay in the fact that I had emerged but had 17 unaltered /etc in etc-update.
I rebooted without considering the consequence of said stale config files.
I will never shut down before checking my config files again. |
