not sure if provisioner did something unexpected

Yeah, understandable

it’s also true I never use local storage since it’s not production reliable

this is strange, I have a lot of clusters that went trough nodes issue but I never lost data

ok so data is not there anymore in mongodb

It shows newly created projects (I mean examples , which are created at the start of clearml)

Ok, willl check that

I suspect no for some reason that is related pvc management, at least for what I know

ok next step is to exec into mongodb pod and check the various docscollections(tables) to see if data is still there

Yep, because of selector

and are you sure you mongodb respawned on same node?

Local Storage

This is pretty weird. If pv containing mongodb data is still the same data must be there. what storageclass provider are you using?

Well, it happened unexpectedly so no, but data must be saved on corresponding persistance volume

ReassuredArcticwolf33 did you back up mongodb before this process?
JuicyFox94 any idea?
