[precise] MAAS warns about missing ISOs even after they've been processed

[Mike]

When the system is installed, opening the MAAS dashboard URL provides a message with a yellow background:
 "Some of the required system profiles are missing. Run the maas-import-isos script to import Ubuntu isos and create the related profiles:
 sudo maas-import-isos"

However, even after running the above process and confirming that everything completed, that warning message remains. The message remained until I began commissioing nodes, at which point it was replaced with the "Commissioning Nodes" message.

The message should have gone away once maas-import-isos had completed - even if I needed to refresh the page to make it update - which I tried but it didn't.

We store this information (whether or not the script maas-import-isos needs to be run) in a value that is cached using Django's cache. However, we're using a cache local to each thread (see CACHES in src/maas/settings.py) so the script maas-import-isos does not clear the WSGI application's cache (it calls "maas clearcache --key=profile-check-done").

A proper fix would be to use a shared cache using memcache.

An easy workaround is to reduce PROFILE_CHECK_DELAY in src/maasserver/middleware.py to a few seconds.

Due to this error I am not able to accept and commission the nodes that I am trying to add.

I too was stymied by this bug at the Add node stage. Rebooting the server cleared it.

[Mike (bild85)]

I confirm that rebooting the MAAS server clears this message too

We fixed this in Quantal by storing the component error states centrally in the database.

The Quantal code may get backported to Precise, we're waiting on various peoples' decisions.

[Julian Edwards (julian-edwards)]

The precise backport is now complete, so I'm marking this fix-released.

[Julian Edwards (julian-edwards)]

I mean SRU not backport.
