[SOLVED] Emergency mode-ext4 checksum and group descriptions corrupted

Having been left without without room for my root partition I had to resize it with booting GParted. After the process was completed, in order to log to my system I get the message:

Starting File System Check on /dev/disk/by-uuid/..........
systemd-fsck[248]: /dev/sda2: One or more block group descriptor checksums are invalid.   FIXED)
systemd-fsck[248]: /dev/sda2: Group descriptor 0 checksum is 0x3c10, shoe be 0xb71b.
systemd-fsck[248]: /dev/sda2: UNEXPECTED INCONSISTENCY: RUN Fsck MANUALLY.
systemd-fsck[248]: /dev/sda2: (i.e. , without -a or -p options)
EXT4-fs (sda2): ext4_check_descriptors: Checksum for group 0 failed (46875!=15376)
EXT4-fs (sda2): group descriptor corrupted
Walcome to emergency mode! After logging in , type "journalctl -xb" to view system logs, "systemctl reboot" to reboot. "systemctl defalt" to try again to boot into default mode.
Give root password for maintenance
(or press Control -D to continue):

I have 3 partiton /dev/sda1 my root partition, a the second on the home partition /dev/sda2, a swap partition /dev/sda3 and the Windows partiton /dev/sdb1.

I don't know what this is and how to fix it.

Enter the root password, enter the command umount /dev/sda2, then fsck -f /dev/sda2
EDIT: Changed sda1 to sda2. My bad.

Re: [SOLVED] Emergency mode-ext4 checksum and group descriptions corrupted

It shows me that /dev/sda2 is already unmounted and on the second command fsck -f /dev/sda2 it gives me questions about group descriptor checksums to fix and press yes. Is there a way to fix all the errors without to have pressing the y?


EDITED
I used the fsck - y /dev/sda2 to automatically use the y to all proposed fixes and in 30 minutes the whole process was completed.

Thank for the help.
