I’ve been trying to upgrade from 13.0 U5.1 to 13.0 U6.1 and have been stuck here for a few days now:
I can’t seem to do anything else in the web ui while this is happening except login after I refresh the browser.
They’re primarily limited by the speed of your boot device, but they don’t take that long.
Is there a way to troubleshoot why it might be stuck?
When I hook up a monitor I just see repeated messages of “plugin_dispatch_values: Low water mark reached. Dropping 100% of metrics.”
Force a reboot.
Delete the failed Boot Image and try again.

OK, trying again, thanks! If I go into the interactive shell on the server, is there some place that I can look to watch for errors when the update runs so that I can see what’s going on?
attach a VGA screen and watch the process.
There are usually two boots.
I was just about to enter 9 to open the shell, but now I am starting to get the plugin_dispatch_values: Low water mark reached. Dropping 100% of metrics. messages and the progress is at the same place as the screenshot above. Are those messages expected during updates?
No.
A search of the Forum indicates a failing Boot drive.
I suggest you save your config…which you did anyway ?
And try a manual install to a new Boot device and then a restore of the saved Config.

Ironically when I search these forums for that message, my post is the only one that comes up. 
So it sounds like my next steps are:
- install new ssd for boot drive
- manual install of 13.0 U5.1 to the new drive
- restore config from backup
Does that sound like a good plan?
I googled “truenas Low water mark reached” to get the old forum as well.
Go straight to 6.1

ah, great, thanks again for your help!
Well I bought a brand new SSD boot drive, removed the old one, added the new one, installed 5.1 and went to run the updates and it is stuck at the same 66.67% Installing base-os (1/3) and the logs have the same plugin_dispatch_values like before. Anyone have any other ideas on how to troubleshoot?
I would manually install 6.1.
