system upgrade fails

bednarjm · 07-01-2016, 08:54 PM

I attempted to upgrade to version 24 through dnf. It downloaded and did its thing. After it rebooted, it got hung up in emergency mode. I'm at a loss at this point and don't know where to go from here. Any suggestions?

Thanks.

Hi:

Type in your root password and than type in:

Code:

fsck

Do you get errors like this when running that command?

Code:

 /dev/mapper/fedora_XXX--root is mounted
      e2fsck: Cannot continue, aborting.

If not what errors if any?

I get
/dev/sda2 is mounted.

Maybe this attachment will help too.

If there are questions about fixing, ignoring, forcing, salvage, etc, always answer y (yes)

I think you will have to unmount your /dev/sda2 in order to run "fsck"

To unmount it run:

Code:

unmount /dev/sda2

Than re-run "fsck"

You might need to post the entirety of your /etc/fstab file and see if that's ok.
-::-If fsck fails you'll need a Live CD or USB to perform a fresh installation.-::-

Here are threads that have the same errors that you have going on that may be of help.

Here's what I got.

Ztcoracat · 07-02-2016, 10:56 PM

Your /dev/sda2 and /dev/sda6 are ok.

I'm not sure what's wrong with sdb1 and sdb2 which look like your Fedora partitions.

When you upgraded from Fedora 23 to Fedora 24 it could be that your Fedora partitions got misconfigured or corrupted somehow. <OR> superblocks might be missing and I don't know how to repair that; sorry.

It appears that you have more than one drive on that machine.
Is that correct?
Did you have to do a forced shutdown?

When I install the new releases of Fedora I always download the .iso and perform a fresh installation with either a CD/DVD or a Live USB. I don't trust upgrades; never have.

Code:

no such file or directory while trying to open sdb1 possibly none existent device?

Is an indication that one of the drives are not present on the system, maybe there is hardware failure (or the USB port where it is plugged in has a failure) or simply that the fs corrupted by a forced shutdown.

I would do a fresh install from CD or USB.
<OR> wait for other members to chime in and give you suggestions.

You should also check the logs for errors.

sda2 is root and sda6 is my home partition.
sd1 and sdb2 are on my data drive.

I usually do a fresh one but last few releases I did the upgrade through fedup. this time i tried the dnf system upgrade.

I ran into this problem to when i tried to boot into rescue. https://unix.stackexchange.com/quest...er-dnf-upgrade

Since I do have a separate home partition, I did do a mostly fresh install last night. It installed fine and rebooted into the new install. I did my dnf updates. Installed my usual dropbox, virtualbox and crossover. Also installed nvidia drivers through rpmfusion. I rebooted and straight to the emergency mode i went. I had to set enforcing=0 on the grub boot script to get past it. Something with SELinux is giving me a hard time.

Ztcoracat · 07-04-2016, 12:53 AM

Jeesseeee-
Sorry to hear that.

You can temporarily turn off SELinux by putting it in permissive mode but I've never tried it.
I hope theses links help.

So i decided to totally wipe my system. Backed up my data of course.

I reinstalled and as i did things i rebooted and kept track of what was going on. Well I edited my fstab file to mount my other partitions on boot and that created the system panic into emergency mode.

Code:

/dev/sdb1 /run/media/jaison/windows_apps ext4 defaults 0 2
/dev/sdb2 /run/media/jaison/data	 ext4 defaults 0 2

That should be correct? I never had any issues in the past with it.

Ztcoracat · 07-25-2016, 07:03 AM

Yes that looks correct.

Did you make a swap partition?

bednarjm · 07-25-2016, 11:14 AM

This is my whole fstab

Code:

UUID=89dee6d7-ea31-4e4e-8834-7014a22aaa77 /                       ext4    defaults        1 1
UUID=edcaa262-ee43-4f4e-9f3a-7f89ccc5dae9 /boot                   ext4    defaults        1 2
UUID=62225ed2-257c-4a09-929e-0447d992aeed /home                   ext4    defaults        1 2
UUID=9b6fd0e0-25cf-480b-a19c-f12e01c9263c /var                    ext4    defaults        1 2
UUID=3e942889-d61a-4d6d-849a-a88da14c7aa0 swap                    swap    defaults        0 0
UUID=5b44c44b-36ac-4144-9a41-063e65e2d1e4 /run/media/jaison/windows_apps                    ext4    defaults       0 2
UUID=a6b7a8ee-1146-4221-a32b-213708223d7e /run/media/jaison/data                    ext4    defaults        0 2

Now if I comment out the ones I added, it will boot fine. Otherwise I have to edit the grub script to add enforcing=0 so it will mount those at boot without tripping the emergency mode.
