Maestro Orchestrator MHO-140 & MHO-175 - /var/log/gaia_api_server.log and multiple Hotfix Takes

Hello There,
I have several customers where Maestro is used. The current Version is R81.10 and multiple Hotfix Takes are installed on MHO.
Now I got an error message on the Orchestrator when I want to import a new Jumbo Hoftix via CPUSE >> "Error: not enough space. The session will be terminated. Press OK to proceed."

When I check the "show asset all" command on the MHO Appliance, it displays a 120GB SSD.
The "df -h" shows me, for /var/log/ partition we got only 20GB and around 2GB are left!

So next I checked all big Files on the /var/log/ partition to find out the root cause.
I was then wondering about the /var/log/gaia_api_server.log File, which is continuously growing and takes nearly 8GB of the 20GB Capacity from the Partition.
Unfortunately, I can't find any information about that log-file. Can someone explain the background of the "gaia_api_server.log" and if it can be deleted?

Is it normal that this log is growing up to 8GB? why there is no log rotation for this log or something like a scheduled job that cleans it up? What will happen with the MHO, if the /var/log/ is completely full because of the continuously growing logfile?


In general, I was wondering about how to clean up the Gaia /var/log/ Partition on a Maestro Orchestrator and how it will differ from a non-Maestro Gaia.

Best regards

Moe

 

EDIT: I just found out that the Log rotation does not work anymore. I will open a TAC Case:

Hi, you can safely remove these log files, we will consider adding gaia_api logs to the rotation infra to avoid this in the future.

Thanks.

Hey @Majd_Sharkia 
Thanks for your response.
Because yesterday I wasn't even able to uninstall any Hotfix Take anymore, I have performed the following Workaround:

Create a system-backup and snapshot in the first place.
After this, I removed the 8GB gaia_api_server.log.
Then I created a new clean/empty gaia_api_server.log.
Because it didn't take effect on the "df -h" output, I restarted the MHO.
After MHO reboot, more disk space was available again on the 120GB SSD and I was able to delete the older Patches.

Best Regards

[Expert@MHO-01:0]# log_start list | grep gaia

   97) gaia_api_server.log                       1048576         10

[Expert@MHO-01:0]# log_start list | grep gaia
   57) gaiaRest.log                             10485760         10

I added new line to file  /etc/cpshell/log_rotation according to sk36798

Hello There,

I tracked this a few weeks since now after I have uninstalled Jumbo Hotfix Take 66 & 81, and installed Take 95 only. After MHO rebooting the issue was solved for some reason. So I guess it's fixed but not listed in the release notes.

Cheers
