Stuck at "A start job is runnig for dev-disk-by...Partition_ID" after Changing Disk Type -> Leap 42.

[brdarkmoon]

Hey Guys,

I´m lost here, i would really appreciate some help.

I exported a vm from esxi where it originaly had a paravirtual disk, since Vmware Workstation doesnt support Paravirtual Disks, i changed it to Scsi, but it is stuck at “A start job is runnig for dev-disk-by…Partition_ID” while booting.
Some INFO:
VM OS: OpenSUSE Leap
Disk Before Exporting: Paravirtual SCSI
Disk After : SCSI

So, i might be wrong but i think that:

UUID for the DISK: Check
FSTAB: Check
GRUB: Check
why is it stuck at “A start job is runnig for dev-disk-by…Partition_ID”, even if everything is correct from the OS point of VIEW.
I Suspect that i must change something else to make it work…but what?

Thank you all in advance

Rebuild initrd, check for resume= kernel parameter. Otherwise we have no idea what it is waiting for so it is rather impossible to make even uneducated guess.

Thank you my friend, you pointed me in the right direction, to help others that could be in the same situation, my exact steps where:
1 - boot from a live DVD, CD, USB(I believe that any distro would do)
2 - open terminal
3 - locate your disks and partitions:
fdisk -l (use sudo if your not logged in as root)
Not sure if the next steps would apply to you, but in my case they were needed.
4 - Execute the following commands
mount /dev/sda2 /mnt/
mount --bind /dev/ /mnt/dev/
mount --bind /proc/ /mnt/proc/
mount --bind /sys/ /mnt/sys/
chroot /mnt
5 - edit boot/grub2/grub.cfg (no / in front of boot otherwise you might end up at the live dvd´s boot directory)
6 - put the resume parameter back to the correct swap partition(in my case it was pointing to a third partition)
7 -mkinitrd
8 - reboot

Presumably, you would eventually get a prompt to press ctl+alt+del or input root password. Usually it means it’s looking for a uuid which is no longer there.
If you input root password open fstab to edit, comment out the offending line and reboot, that’s a bit shorter than what you did. When you get back into the system you can correct fstab.

Hey Pete,

I tried that…9 hours passed and there were no signs of it giving up or doing something else, besides like i said on my description, all uuids were correct.
But thank you, because sometimes if we try what you suggested, it will work, unfortunately my problem was something deeper.
