partitioning - After resizing partition Ubuntu boots in emergency mode

After resizing /home directory on my Ubuntu 18.04 (used Gparted while booting from LinuxMint-LiveCD my Ubuntu boots exclusively in emergency mode. What can I do to fix it?

I ran lsblk in emergency mode, and saw that:

1. my /dev/sda3 (/home) partition was unmounted (its size was changed)


2. unallocated space presumably still is considered as part of sda device (because sda size is shown as before 931Gb), but not recognized as /dev/sda4 or anyhow.

After mounting /dev/sda3 to the system I am able to start a normal session, but after reboot it happens again.

What can I do to make my Ubuntu boot normally again?

Content of /etc/fstab:

#                
# / was on /dev/sda2 during installation
UUID=d5eb2396-e9df-4a63-84da-d628c915d809 /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/sda1 during installation
UUID=3E0D-5C34  /boot/efi       vfat    utf8,umask=007,gid=46 0       1
# /home was on /dev/sda3 during installation

UUID=f79558ec-8e55-4fa5-81ed-b6c77c87a43b /home           ext4    defaults        0       2
/swapfile                                 none            swap    sw              0       0

I solved the problem in the following manner:

1. In the emergency mode, I ran journalctl -xb | less and searched for errors.

It appeared that /dev/sda3 couldn't pass control sum check and therefore was refused to be mounted. Fortunately right there was a proposition to run manually fsck /dev/sda3 to fix it.

2. I ran fsck /dev/sda3 and, in a while, it fixed the problem.

Since then I didn't have problems booting into Ubuntu.
