Hi @benjamin,
Thank you for your response.
Q1.
Yes, all machines have 1TB of space, available store on all unit is 900+ GB free space. It just has the Ubuntu 16.04 OS, and Kolibri installed.
Q2.
No, The error ref: “…sanity_checks Port 8080 is occupied.” occurs after kolibri upgraded, the default owner becomes root, I then login as root user, run the command to stop kolibri, then i give all permission to kolibri over the .kolibri folder. Reboot and then kolibri runs from the kolibri user just fine without the error: “…sanity_checks Port 8080 is occupied.”.
When this happened:…“sanity_checks Port 8080 is occupied.” when i run the command kolibri status… I immediately checked the permmisions on the .kolibri folder. I will run the command ps ax | grep kolibri to double check for you.
Q3.
No, there are none. However I have noticed this error: “WARNING 2019-01-25 11:21:50,445 ping Ping failed (could not connect). Trying again in 15.0 minutes.” only when there is no internet access. Testing offline.
Q4.
Kolibri is working. When users start logging in, and accessing content within 10-15 minutes, the kolibri bird loading image is displayed, users start seeing “disconnected from server…etc” then it becomes unstable.
Yes I would like you to assist me in trying to restore the db, if it is broken.
Also I have seen the Disk I/O errors on all the previous versions while installing kolibri, ref: Manually verify import content on database file have a look here.
Looking forward to your reply.
Thanks so much!
