OMV6 is Unable to sleep/standby

Hi,

I am unable to set the system to sleep/standby.

The action does not have any effect.

Logs from syslog:

My fstab:

I am using the flashmemory plugin as I did on OMV5. On such OS (same hardware) I was able to set the system to sleep. What has changed now?

Hi I am referring to the system standby/sleep, not to disks spindown. The latter can be accomplished with hd-idle, I wrote a guide on this forum.

Resolved: I booted with a GParted live disk and extended the swap partition.

I have installed OMV6 on a USB stick, as I did for OMV5. (specs in my signature)

However the install didn't go very smoothly - issue here - but I don't know if It had a direct impact.

The original size of the swap was very little, just under 1 GB.

The RAM was not changed after the install. I always had 8 GB RAM installed on this setup.

The previous OMV5 install had the correct size swap partition, but I can't remember if I did something to it since it was installed on February 2020.

By the way, if the RAM content has to be copied to the swap partition, do you know why the sleep process is so fast?

My system on average uses 2.5 to 3 GB RAM and the sleep process takes literally a handful of seconds, but my USB stick isn't that fast. How is this possible? I'm not complaining, I just don't understand how is accomplished.

Zitat von mi-hol

do you remember the kernel version that got installed? the linked picture would let me assume a 5.14 kernel (but only indirectly).

LTS kernels considered good are 5.10 and 5.15

the kernel version is visible in dashboard/system information or by CLI uname -a

Indeed, I think 5.14 was installed.

After the install I ran the command omv-upgrade so I'm running the latest and greatest 5.16.

By the way I have discovered the root cause of this issue: the OMV GUI has moved from systemctl suspend to systemctl hybernate. I will create a new thread to discuss this.
