I use Ubuntu 18.04.4 LTS and recently I replace my hard disk with another and change /etc/fstab file:
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda6 during installation
UUID=287d1a83-ed10-4dff-8b3a-acca224d8cb0 / ext4 errors=remount-ro 0 1
# /boot/efi was on /dev/sda2 during installation
UUID=36EF-F7C0 /boot/efi vfat umask=0077 0 1
# /home was on /dev/sdb3 during installation
UUID=4229bf67-6e83-4c25-bd03-8583f3a75c5a /home ext4 defaults 0 2
# swap was on /dev/sda7 during installation
UUID=48d1eac5-afac-4deb-88ab-0b9528dc7467 none swap sw 0 0
# swap was on /dev/sdb1 during installation
UUID=a8c63b5b-9d21-4a72-b059-3348e4a4333b none swap sw 0 0
So, now my system boots in the right way, but my booting time greatly increased and in /var/log/boot.log file I found such line
#/var/log/boot.log
[^[[0;1;31mFAILED^[[0m] Failed to start File System Check on /dev/disk/by-uuid/426d7a71-bdfe-4b58-851d-9b023b968211.
See 'systemctl status "systemd-fsck@dev-disk-by\\x2duuid-426d7a71\\x2dbdfe\\x2d4b58\\x2d851d\\x2d9b023b968211.service"' for details.
Where 426d7a71-bdfe-4b58-851d-9b023b968211 is my old partition UUID.
Here is systemctl status "systemd-fsck@dev-disk-by\\x2duuid-426d7a71\\x2dbdfe\\x2d4b58\\x2d851d\\x2d9b023b968211.service" output:

It's seems like systemd-fsck ignore /etc/fstab file and trying to check nonexistent partition.
如何预防呢？
