Expertise Forum Badges

The TrueNAS SCALE Knowledge Exam Badge Level 1 exists to allow users to take a test and receive a badge. The description says: “Completed the TrueNAS SCALE Knowledge Exam scoring 80% or higher.”

I have a few suggestions regarding this:

  1. They should be better advertised - encouraging forum members to become more knowledgeable about the software that they use is IMO a good thing.

  2. When people take the certification tests, the results should be processed and badges awarded and feedback given. AFAICT the process for awarding this badge may have stalled. (Disclosure: This overall post is a general one made for positive reasons, but it was prompted by noticing that I didn’t receive this badge despite having successfully completed the test some months ago. I just took the test again so hopefully the badge will now appear.)

  3. It would be great to have additional levels of expertise and further more advanced tests defined.

  4. The TrueNAS documentation is great, but it seems to be designed to be reference or help material when someone has a specific task to do rather than curated training material to help people build a knowledge base. Creating course material is time-consuming and therefore expensive, but even a set of curated reading lists to point people at other sources of training material would be beneficial.

    The closest thing to this at the moment seems to be (the partially updated/partially complete) Uncle Fester’s Basic TrueNAS Configuration Guide. (Disclosure: I am the author of some parts of this.)

If iX would consider it helpful, I would be happy to try to come up with one or more suggested tests for more advanced qualifications.

My thoughts are that these should be topic based, and here is a brain dump of possible badges:

TrueNAS SCALE Knowledge Exam - Basic Pool Design & Creation

When to use mirrors or RAIDZ, when to use RAIDZ1/2, compression, snapshots, basics of SLOG, L2ARC, special metadata

TrueNAS SCALE Knowledge Exam - Pool Management

Increasing the size of a pool, replacing disks which have failed

TrueNAS SCALE Knowledge Exam - Pool Diagnostics

Basics of how to diagnose pool issues and avoid making things worse

TrueNAS SCALE Knowledge Exam - Networking

Basic network setup, file sharing & permissions, performance expectations

TrueNAS SCALE Knowledge Exam - Containers

Apps, VMs, LXCs, Incus VMs

This is the area most subject to ongoing change in new versions of TrueNAS

TrueNAS SCALE Knowledge Exam - Advanced Expert

The most challenging and highly detailed set of questions which can only be answered by the community members who have deep expertise in diagnosing and fixing the most obscure TrueNAS configuration or operational issues. The sort of test that perhaps only @kris and @honeybadger could pass, but the rest of us mere mortals could aspire to achieving.

This made me try the exam but I have objection :smiley:

Disks can be redundant, definitely not pools or vdevs :slight_smile:

It’s the wording.

It should have been phrased like this: “In ZFS, redundancy is determined from which component?”

I have made the same mistake :smile:

Just make it easy so I can pass the test, or provide me the correct answer in advance :grimacing:

My suggestion would be for you to come up with a Multi-Report test for a Multi-Report badge as I suspect that you will be able to pass that test and get the badge yourself.

Yes - I got the same question wrong both times I took the test.

  • A vDev is the storage component that can have redundancy.
  • The redundancy itself is created from disks.

I got one other question wrong too - use of emptyDir as a "scratch space for temporary data.

That is funny. Even I’m not sure I could pass it. Permissions kicking me in the shorts. Also, it really isn’t part of TrueNAS.

A few good questions could be about recognizing errors and what category to place them in. For example, ZFS error or Drive failure?

But I do learn from those exams like questions about replication. I don’t know that stuff, but that is because i just do not use it. So even if I fail an exam, it still help me learn something.
