Not alert when boot pool degraded?

[pawel30w]

Hi All,

I am quite new to the Truenas but wanted to ask if the following behaviour is a bug or it's normal but I am missing someting.

I decided finally to add second SSD to my boot pool i.e. mirror it.

After adding the second drive I wanted to test the systems behaviour when one of the drives is not available. I shut off Truenas, disconnected one of the drives and booted up again. There was no alert that the pool is degraded unless I went to settings where it was shown. I repeated this again for the second SSD and the same situation -> Truenas booted up fine but no alerts that boot pool is degraded.

I understand it is very unlikely that SSD go bad but it would be nice to be informed asap instead of manually checking it in settings. You could write some script but I guess this should be automatic.

I did this excercise when drives connected through SATA or USB (using USB 3 -> SATA dongle) and exactly the same behaviour.

Screenshots attached.

My system is as follows, TrueNas installed bare metal on:
TrueNAS-SCALE-23.10.1.3
Supermicro X10SRi-F
E5-2620 v3 @ 2.40GHz
32 GB ECC RAM
Pools:
bootpool: MIRROR 1x GOODRAM 240GB, 1x Kingston 240GB
tank: RAIDZ2 5x 4TB WD Red's RAIDZ2
backuppool8tb: STRIPE 2x WD Red 3TB, 2x WD Red 2TB
Spare2tb: 1x Segate 2TB
SSDPool: 1x 500GB

Not related to your question: 94 % usage on your pool is way too much!
Add space / delete files before that pool dies.

I would think this is a bug and if you wouldn't mind, report it using "Report a Bug". I'm certain not many people have done this test, even less with SCALE. I for one would like an Alert message. If it's not a bug and is done intentionally (which I highly doubt), the developers will tell you.

Please post the bug report link here as well so others can fallow it.

And I completely agree with @chuck32 You need to bring your pool capacity back under control. 94% is too high and if you do not know what we are talking about, I suggest that you do an internet search on something like "truenas 80% pool" and I'm sure some things will pop up.

Once you either increase your capacity or reduce your data, you can easily keep this in check by setting a quota for the entire pool so it will not go over 80%.

That's what the alert system is there for... I guess you haven't defined an alert method, hence no alerts came to you.

Click on the bell in the top right of the UI, then the cogwheel, then Email and/or Alert settings to make sure you get alerted for things you feel are important (if the defaults don't suit you).

Wanted to chime in and say I've also run into this. I've received email alerts for my data pool with drive failures, but decided to check my boot pool one day and noticed that it was degraded.

Apparently I had the same issue a few days ago.

If I'm not completely mistaken this issue should already be addressed and fixed. Maybe, just in case, save a debug file? I already reinstalled my OS and unfortunately did not think about saving the file first.
