No logs after launching zram #116

Closed skibbipl closed 2 months ago

skibbipl commented 2 months ago

So I decided to experiment on a VM with zram config. I installed debian testing and installed zram-config. Installation went smoothly without errors but journalctl stopped working. What I can see after reboot is:

jul 28 22:17:45 temp systemd-journald[286]: Journal stopped

Am I missing something? I expected that logs will work without issues, but it seems that there is no logging at all after installing zram-config. My ztab is unchanged:

log     lzo-rle         50M             150M            /var/log                /opt/zram/log.bind      /opt/zram/oldlog

Trying to enable sytemd-journald ends with error:

root@temp:~# service systemd-journald start
A dependency job for systemd-journald.service failed. See 'journalctl -xe' for details.

One issue you are probably going to run into is that generally speaking zram won't work properly in a VM. This is one of the reasons that I use a custom emulated image for my testing suite on GitHub.

Have you tried an install on a non VM and observed the same issue?

Thanks for pointing this out - perhaps it's worth updating known issues part of the documentation? I will check it on my raspberry pi, however I wanted to implement it on proxmox node which runs temporarily on pendrive.

For sure, I'll look into adding a note about that. Thanks for the feedback!
