Slow Boot Time due to fsck

I am having slow boot times after moving /home to a HDD. The mounting of the HDD is taking long time.

Here's my

I don't know why this is happening. This is my 

lsblk

sda is my HDD and sdb is my SSD.

└─sda1   8:1    0 298.1G  0 part /home

Re: Slow Boot Time due to fsck

I wouldn't call a 12sec boot time with a HDD as too slow especially when accounting for the file system check, fsck doesn't run on every boot or is not supposed to anyway (default is to run on every 30 boots if I remember correctly). Have you tried booting again to compare your boot times?

Re: Slow Boot Time due to fsck

What file-system is /home?  Is fsck being forced due to not being unmounted cleanly?  Please post the system journal for a boot.
