Swap file creation broken?

Troubleshooting
#1

Hello,
I try to create a swap file on my odroid and my pi 3.
I do dietpi-drive_manager → selecting the drive → create swap → 1 → enter (or tab enter) → magic things happening. After that there is no X in the “[]”. When I navigate again in the create swap menu the value is again 0. This happens everytime.
Is this normal?

if you are connected via SSH, you should be able to scroll up a little bit. There you should see some information above the blue text box. Could you share that information pls.

where do you like to store the SWAP file on? On which file system? Can you share following pls

lsblk -o name,fstype,label,size,ro,type,mountpoint,partuuid,uuid

I tried to store it on mmcblk1 it’s a emmc module.
For the odroid n2+…
Do you want the same information of my pi?

#6

If you try to create the swap space on the drive manager, you will be ask on the size. What value did you specify there? How much physical memory you have?

#7

I have the 4GB Odroid n2+ model.
I want the auto mode.
So I Type „1“ into the field.

#8

In case of 4GB physical memory, no SWAP file is created using the automatic option 1. We create SWAP files for system having less than 2 GB memory only. If you require a SWAP file anyhow, you need to specify the size manually :slight_smile:

#9

Background is that for most installations 2 GiB memory are sufficient, so the auto mode is only to assure that users don’t run into dietpi-software installation errors and all services start up. For more intense usage we cannot reasonably predict how large the swap file needs to be.

Good to know, thank you.
