I've a cluster of 5 webnodes with moodledata mounted via NFS.
Running CentOS 8, SELinux disabled (had to be donne..). All nodes are equal.
I've compiled from source sbcl-2.0.3 and maxima-5.42.2.
The healthcheck script runs without problems,and I can generate the optimized image without problems.
OK CAS returned data as expected. You have a live connection to the CAS.
OK Correct and expected STACK-Maxima library version being used (2020042000).
Load optional Maxima libraries:
CAS results are being cached in the database.
Yet, sometimes I run into errors.
And I have things like this: CASText failed validation. CAS commands not valid. Forbidden function: plot3d. and contour_plot.
On Moodle I use the platform Linux(optimised) and maxima command: timeout --kill-after=10s 10s /moodledata/stack/maxima_opt_auto
This made me question a few things:
- Since this is a cluster, should one image on each server wihout having one shared to all node on Moodle server?
- Since it was compiled from source, should I use the platform Linux instead of the optimized version?
- It's the maxima command correct?
- Should I use older/other versions of sbcl and maxima?
