The following message is shown in show system snapshot media internal after Junos OS is upgraded from the 12.3R train to 13.2x and later versions:
show system snapshot media internal
WARNING: snapshot format is incompatible with the software currently running
After upgrading the Junos version from the 12.3R train to another train version, a warning message is displayed, as follows:
root> show system snapshot media internal fpc0: -------------------------------------------------------------------------- Information for snapshot on internal (/dev/da0s1a) (primary) Creation date: Dec 6 10:06:37 2015 JUNOS version on snapshot: jdocs-ex: 15.1R1.9 junos : ex-15.1R1.9 junos-ex-2200: 15.1R1.9 jweb-ex: 15.1R1.9 Information for snapshot on internal (/dev/da0s2a) (backup) Creation date: Dec 6 07:42:53 2015 JUNOS version on snapshot: jbase : ex-12.3R3.4 WARNING: snapshot format is incompatible with the software currently running <<<<< <HERE !!</span> --------------------------------------------------------------------------
This output is coming from a bootup script that is identifying the Junos image directory between the primary and secondary slice. Since 13.2x and later releases, the Junos package directory has changed, hence this message is shown.
Use the request system snapshot command to fix this issue.
