Slow boot after removing a HDD

Had this problem ever since I removed another hard disk drive.

% uname -a

% systemd-analyze critical-chain

Re: Slow boot after removing a HDD

Is there a reference to the old drive in fstab?

Re: Slow boot after removing a HDD

Solved it. The problem  was with the UUID of a swap partition.
