[j-nsp] JunOS upgrade to 8.5R1.14, boot device too small ?

[Mykola Mitrokhin]

Hello,

I have a problem with upgrading one of our juniper routers, currently it is
running JunOS 8.3.
I wanted to upgrade to -8.5R1.14

I started the upgrade and it ends with the following error:

*********************

Adding jinstall...

WARNING: This installation will not succeed.
WARNING: The boot device is less than 256M.
WARNING: A hardware upgrade is required.

ERROR: jinstall fails requirements check

**********************

How can i fix this? I use RE-2.0 333-768



Thanks for your help in advance.



Best wishes,

mykola
