Fedora boot stuck on Job dev-disk-by

Deleted swap partition in order to resize the root partition in order to be able to download system software updates.

After restarting, the boot stays stuck on Job dev-disk-by.

Cannot boot into any of the three kernels or rescue, but grub command line is accessible.

Running cat /proc/cmd/ gives error command not found. Running ls gives (memdisk) (proc) (hd0)…

As an alternative, booted a livecd, deleted the resume=x line from etc/default/grub, saved, restarted, but the boot remains stuck.

Without a new install, can anything be done to fix this boot issue?

Added boot, filesystem, root, swap, workstation

Hi and welcome to :fedora_classic: !

Did you increase the storage size of your root partition? Can you tell us where the swap partition was, and where the root partition was and is now?

This may be an issue in your fstab or something, trying to mount root but there is no first partition. But no idea.

try searching for it, many results that could match

Mh. I think that if you modify /etc/default/grub you are supposed to rungrub2-mkconfig in order to regenerate the grub configuration.

In addition. What about /etc/fstab?

(However I installed a VM with a swap partition, deleted it, and the system boots anyway, so I think that your issue is more complex ).

Thank you.

Yes, I increased the size of root.

Both the root and the swap partitions were under the same hard disk, altogether there were four partitions, now three.

Using the search results, I opened fstab and it contained:

overlay / overlay rw 0 0
tmpfs / tmp tmpfs nosuid,nodev 0 0

Crypttab contained:

# <target name> <source device> <key file> <options>

That looks like a header row, and there were no devices to comment out as I interpreted as the step that needs to be done.

your crypttab output is empty?

Also you can format your code using the code symbol in the edit window :smiley:

I think that it is normal if the disk is not encrypted.

This looks strange, where is the root partition in example?

What program did you use?
Are you using Fedora Workstation or some other spin/edition?
Is the disk encrypted?
Can you provide (from the Live system) the result of the command
lsblk -o name,fstype,size

Removed the swap partition line from fstab, but can’t get or find how to run the grub2-mkconfig.

I used the terminal to delete the swap partition and resize the root partition, and I am using Fedora Workstation. One of the partitions are encrypted, but not the root partition.

the terminal is not the program that you used ;D

What command did you use to delete the partition? And if you followed instructions, where are they?

12

I actually think I used Disks to unmount and delete the swap partition, and then used resize2fs to increase the size of root.

I didn’t want to delete the swap partition because there was available unallocated space on the disk, but couldn’t figure out how to do that.

13

Before removing the swap partition from the disk, it is important to check if there are any references in the /etc/fstab file to the swap partition or if you have a resume= in the kernel command line. To check the kernel command line, run the command cat /proc/cmdline.

Especially, the resume= option would cause the system to wait forever for the swap partition to become available.

The command lsblk -fp will show the UUIDs you should be looking for when check /proc/cmdline and /etc/fstab.

On my system this file has a warning that it is not used.

$ cat /etc/inittab
# inittab is no longer used.
#
# ADDING CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.

Sorry; /etc/fstab of course.

Thanks to everyone for the help. This is all good to know.

After several attempts, I wasn’t able to do get it to boot, but had a backup so a new install resolved it.
