Swap Partition not added to Fstab after Manjaro Gnome install

Support
1

Hi everyone,
I was experiencing extremely frequent irrecoverable system freezes on my freshly installed Manjaro Gnome system. One day I was just checking the details of all my partitions and found that my swap status was “Not Active”. So I checked the fstab file and sure enough, there wasn’t an entry for the swap partition. I added the swap partition to the fstab file and the freezes haven’t occurred since. BTW, my swap partition is on a different disk compared to my other partitions so that might have something to do with this but I can confirm that I correctly chose, labelled and formatted the swap partition during setup.

Thanks

Looks like it’s being used. What’s the output of:

cat /etc/fstab
3

You can enable it with Gnome Disk utility

4

Yes, as I wrote, I did add it to the fstab when I found out. I am not asking for a solution but rather reporting this so the devs can find out why swap was not added to fstab during the install.

5

I have made a manual partioning and added a “mount point” for the swap partition.
Works as expected.

6

Was your swap on a different drive?

7

systemd automagically mounts swap even if not defined on fstab

https://systemd.io/DISCOVERABLE_PARTITIONS/

8

Is PARTUUID the same as Part Type UUID? If yes, then my swap partition’s PARTUUID doesn’t match the one in the systemd documentation.

9

No - partition uuid is different from partitiontype uuid

paritition uuid changes on formating or repartitioning - but partitiontype stays the same (that is unless you deliberately change it or filesystem corruption occur) - it can be set or changed by a GPT partition manager - such as cgdisk or parted - only when the device is unmounted.

for the curios

lsblk -o name,uuid,partuuid,parttype,parttypename

I checked and my parttype uuid is correct but for some reason, it was still not being automatically started by systemd.

NAME         UUID                                 PARTUUID                             PARTTYPE                             PARTTYPENAME

And just something off-topic, I noticed that the inxi -Fxxxz says my display server is X.org but Gnome settings says wayland.
