[c-nsp] ASR9K upgrade from 4.2.0 to 4.2.1

Wed Jun 6 12:05:08 EDT 2012

I have a 4.2.0 ASR9k installation with a few pies and mandatory SMUs installed to facilitate an upgrade to 4.2.1.  It seems that in it's current form, the 4.2.0 installation I have is consuming 1GB of space on disk0: leaving less than the required amount of free space to be able to do the 4.2.1 upgrade.

I've always been baffled by the ASR9K filesystem.  The disk0: seems to store much more than installation images and it seems something has decided to chew up lots of free space making an upgrade impossible short of the less than desirable turboboot option.

Has anyone experienced a similar issue where their disk0: is choked full of stuff?

Here's a snapshot.  As you can see, very basic, stripped down 4.2.0 installation, yet only 500MB free on disk0:
