Dear all,

I've been getting some strange messages when booting and shutting down.

When I booting a see very quickly passing messages about "mount", but
they pass to fast to see. (The "break/pause" key doesn't work.) I could
not find these messages with "dmesg" or in "/var/log/syslog"... (BTW,
Is there another place to find these messages from boot and shutdown.
This is independent of this problem. It's just something I'd like to
know for the future.)


One message that I see is something like "/dev/sda6" not found or could
not write... (I am sorry I can't be more precise.)

Since I changed the default fstab, I thought I had messed it up
somehow. (This is a new installation, but up to date.)

Here are the details:

      Code:

root@debian[/home/finotti]# infobash -v3

Here is the original fstab:

Here is the new one:

Note that i both the swap partitions have no UUIDs:

(They do have IDs.) I don't know why, as the swap partition of my
laptop does. Is this a sign of some problem? (They do have IDs,
though. Should I use them instead?)

Here is fdisk -l:

All partitions seem to be working, though, but the messages (especially
since I cannot read them) are getting me a bit worried.

Any help with any of these issued would be appreciated.

Best to all,

Luis

If I am reading it correctly, the UUID of your root partition was changed, from the original /etc/fstab file, to the new one. Why would that be? Can you confirm that it is still correct (as root) with

      Code:
ls -l /dev/disk/by-uuid

That is very odd!

Well, the result of "ls -l /dev/disk/by-uuid" was in the original post. Root should be the one in the original. The UUID of the root partition in my new file doesn't even seem to exist, and I have no idea how I got it. (What I did wan get a copy of the original and just change the mounting points...) It is surprising that I can boot at all.

Thank you dibl so much for finding this. I will fix it and see if it fixes the problem.

Best to all,

Luis

If you boot to runlevel 3

( enter e on grub and then edit the kernel line ( the one with "linux /boot...") and add at the end 3 - after that press Ctrl-X to boot.

then you can scroll up and down over the most part of the boot messages (use Shift+PgUp/PgDn)[/b]

OK, thanks all for the help.

Indeed getting the correct root directory in fstab solved the error messages about mount on boot.

I still get some messages regarding /dev/sda6... Thanks yo x-un-i, I can read them, but forgot to write it down. I will check again when I can reboot.

Thanks,

Luis

OK, the message I've been getting is from initramfs. Here is what I've got with a DU:

      Code:

update-initramfs: Generating /boot/initrd.img-2.6.36-0.slh.3-aptosid-amd64
/etc/initramfs-tools/conf.d/resume: 1: /dev/sda6: Permission denied


As you can see from the original post, sda6 is a swap partition. Changing it to the other one (which would be the prefered) /dev/sdb3 gives the same error (with /dev/sdb3 instead, of course). It seems that I do have swap, though:

      Code:

root@debian[~]# free
             total       used       free     shared    buffers     cached
Mem:       8197648    1418132    6779516          0     111536     600548
-/+ buffers/cache:     706048    7491600
Swap:      9148976          0    9148976


Here are the permissions:

      Code:

root@debian[~]# ls -l /dev/sda6 /dev/sdb3
brw-rw---- 1 root disk 8,  6 Nov 11 06:51 /dev/sda6
brw-rw---- 1 root disk 8, 19 Nov 11 06:51 /dev/sdb3


So, here are my questions:


    1) Why am I getting the "permission denied" warning?

    2) Why do the swap partitions have no UUID? (Is it normal?)

    3) Is there a different way (than what x-un-i suggested) to read boot/shutdown messages?


Thanks to all,

Luis

Something is definitely wrong -- the swap partition should have a UUID same as the others. Here is my list, for example:


      Code:
don@sidbox:~$ ls -l /dev/disk/by-uuid
total 0
lrwxrwxrwx 1 root root 10 Nov 11  2010 0c423529-961e-4526-8016-c14da6f1a863 -> ../../sdb3
