Unable to mount home partition

vitoo · 2022-02-05 22:39:03

Hello. I separated a part of my home disk and formatted it as a different partition in a different file format. I mounted it to the root partition as a separate partition. Then I changed my mind and unmounted this partition and re-mounted it to my home partition. When I reboot the system, systemd goes into emergency mode and when I use the lsblk command, my home partition doesn't seem to be mounted to /mnt/home. I am attaching my fstab file and error images:

(/dev/sda5 = root, /dev/sda7 = home)
<emergency> <lsblk> <mount> <fstab>

-> I thought it might be the problem as I was merging two differently formatted fields. Again I allocated a space of the same size and formatted it using mkfs.ext4.
NOTE: I can simply format my home partition by doing mkfs.ext4 but I don't want to lose my configuration and files. Thank you for your help.

Edit: I'm adding lsblk and emergency links right away.
Edit 2: All links are working.

You are going to need to clean that up a little so we can understand what you did. For example"

I mounted it to the root partition as a separate partition. Then I changed my mind and unmounted this partition and re-mounted it to my home partition.

One does not mount partitions on partitions. One mounts them on mount points. You probably want to mount the partition containing your user directories on the /home mount point of the root file system.

I suggest you boot your install media, and work this out in a chroot. When you can mount your root partition on /mnt/, and your home partition on /mnt/home and you can chroot in and the stars align -- then you can try booting your system directly. Don't forget to ensure your /etc/fstab is still valid.

There's no valid filesystem on sda7 you'll have to fsck that, possibly using an alternative superblock.
I'm not sure what you solitmerged how, but if you shrunk a partition w/o shrinking the filesystem first, you might already have caused some data loss and the filesystem might no longer be reconstuctable.

Sorry, it's a bit complicated. I formatted the partition I created later and added /home (/dev/sda7) by expanding it.

I restarted the system from the iso file and tried to mount it, but I got the mount error I gave in the screenshot.

Thanks, I will try that.

That makes no sense - you best list the commands you used, step by step.

Thanks for your help, I ran fsck and a huge part of my /home directory is corrupted. I will reinstall the system.
