Swap cofiguration for raspberry

mcgyver83 · 26. September 2019

Hi all, I'm running OMV in a raspberry pi B for a couple of years.
I find out this line in syslog file:

Code

systemd[1]: Failed to activate swap /var/swap.
systemd[1]: Dependency failed for Swap.
systemd[1]: swap.target: Job swap.target/start failed with result 'dependency'.
systemd[1]: var-swap.swap: Unit entered failed state.

and after some lines

Code

systemd[1]: Starting Initializes zram swaping...
init-zram-swapping[849]: Setting up swapspace version 1, size = 121.2 MiB (127098880 bytes)
init-zram-swapping[849]: no label, UUID=f55f41cc-df07-4cfa-8ede-4524c6559dc3

and startup ends with this:

Code

sudo swapon -s
Filename				Type		Size	Used	Priority
/dev/zram0                             	partition	124120	0	5
/dev/zram1                             	partition	124120	0	5
/dev/zram2                             	partition	124120	0	5
/dev/zram3                             	partition	124120	0	5

Is all fine?
At the end I have swap file with zram never used, does OMV manage swap stuff or can I configure zram and swap myself?

Hi,

Post the output of

Code

sudo cat /etc/fstab

Same situation with rpi4. The main question is should swap to be working with rpi or not, if so where is it should be located (zram, sd, somewere and should i fix it with chmod 600 /var/swap)?

systemctl status var-swap.swap
