Messing around with swap and encrypted swap made my system boot 1 minute and 40 seconds longer

I've been experimenting with swaps and I have reformatted my swap drive to include encryption for it so my system do not need to leak encrypted data while unencrypted on the swap partition. I have made the reformatting with Gnome Disk and everything seemed to work, except it didn't. First I made a swap-enc partition, then when I experienced it doesn't get mounted automatically at boot as dev/sda3, I have decided to just simply disable the mounting of the swap. I have head to Gnome Disks, and reformatted again, the only difference now it is unencrypted (not secured by LUKS). It was all good and everything, it doesn't mount automatically except systemd seems to search for the old partition which doesn't exist anymore. I was left with no clues since fstab indeed contained swap-enc, but after I removed it, I don't know what to do. It's still the same. I can't find anything where to change or remove things, systemd seemingly wants to mount non-existent volumes. Please help me as my boot is very slow right now.

blkid shows the swap uuid and fstab uuid match.

What is the output of

sudo nano /etc/fstab

# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

EEB46G25B46EF00F is another hard drive used by me to store my old files.
The thing is which confuses me, swap has the UUID: a40e7bdd-245b-4d89-98a7-f96fd58b05fa and /dev/disk/by-uuid/dab49aea-e556-4b17-adcb-042555cbdb67 seem to be non-existent anywhere I go. Not in fstab, not in grub files, systemd files, not in /dev/disk..
Seems like there is no trace to it. I have removed swap-enc from fstab however back then when I was reformatting (and deleting it).

Gnome Disks shows the swap, but Gparted doesn't even seem to pick it up at all.

It seems to me as systemd / cryptsetup wants to mount this something out of nothing but thin air.

Already tried, didn't help. As I was digging through stuff, I've found some things but those seems overly complicated to me and not even sure it works on my system. (Arch forums)

In fact, I don't need swap at all. It seems to only freeze my systems occasionally when I run out of ram instead of the kernel terminating the processes. Without swap it seem to terminate correctly as far as I've seen it. And in fact, I don't even use the swap anymore, but that is unrelated since the swap-enc should not be mounted anymore at all, because it is NON-EXISTENT.

When I still have had the swap-enc partition it was done by Gnome Disks. I had added to the arguments (fstab) LUKS because it was an encrypted partition with a swap partition inside it. It got also nofail argument and was set to automatically mount at system start. However, systemd never asked for that one's password and was eventually timed out. Okay, fine. Then I head to reformatting that partition to non-encrypted non-LUKS bare bones swap. And the thing is mounting that exact same drive didn't disappear. I tried to remove it from fstab, and I indeed did remove it, however, systemd is still trying to mount it. This may be a case, because I did not remove the luks entry in fstab aka Gnome Disks arguments and haven't restarded my machine to fix it, but I am not sure.

I have tried getting into root dir with chroot and running mkinitrd but Zorin did not seem to recognize the command.


The elephant in the room was cryptsetup. While I was reformatting the partition in Gnome Disks, apparently GD forgot to detach it from cryptsetup, and systemd wanted to mounted like it was still there. I've found the corresponding files in /etc/crypttab and there it was, the error.

# Output of /etc/crypttab
sda3_crypt UUID=46c7f116-6331-4d13-875e-daf3a1c1decb none luks,discard
swap-enc UUID=dab49aea-e556-4b17-adcb-042555cbdb67 none luks,discard

I have removed swap-enc UUID=dab49aea-e556-4b17-adcb-042555cbdb67 none luks,discard and everything went fine again. Systemd does not want to mount that anymore. The boot procedure is fine again, it is super fast. :slight_smile:

I recommend the Zorin OS developers taking a look at this issue, because this is one of the many things why Linux is not suitable yet for beginners.

Anyways thanks to everyone who helped me, even a little bit. I appreciate you.


Zorin Group stated they do upstream merges :wink:

Contribute more upstream.

When Zorin OS improves, so should the Linux desktop ecosystem as a whole. As we upgrade the underlying technologies, we endeavor to submit our patches to the original developers so all users benefit.
