Disabling the RAM disk and subsequently rebooting causes the boot environment to become unbootable.

Do you have Nexus/MIM enabled?

Is it something we need to have installed & enabled?

It kinda looks like something that would be in the core build and only used only if required.

It's included but disabled by default. When you enable it the config is processed through the MIM backend which can introduce unexpected results.

We have replicated this particular issue reliably now though. Fix is incoming.

Any updates on this?

stephenw10

Yes, that should be fixed now. I'm not sure if it made the May 7th build but it will be in the next one if not.

Can you inspect the contents of /cf/conf/RAM_Disk_Store from the recovery shell after a boot failure?

ls /cf/conf/RAM_Disk_Store should do it

@w0w I bet you are going to see a file pfnet-controller.db.gz in that directory

Yep and another one too, .bak

Thanks for verifying!

We've got a root cause now, and are assessing potential solutions.

This will make it into 25.03.

stephenw10

Yup, turns out it wasn't fixed. Just hiding!

Should be fixed now!

Confirming. Applied 34c529de27b79cfbbcd0e266e17ca7809f3b2a88 patch and all good now.

Sorry but something else is missing, the bug is back Immediately after update to 25.03.b.20250515.1415, ramdsik already disabled.

stephenw10

You'll need to reapply the patch to that. The fix was put it just after that was built. It will be in the next public build.

@stephenw10
Ok. Will try later
