The customer intends to pre-install SNOS on QFX5k or EX4300 switches before integrating them into the Fusion fabric but encounters a low free disk space issue.

When attempting to join a switch running a different version of SNOS X to an existing Junos Fusion setup, the
switch is manually converted to a satellite and the image is pushed to the device. During the upgrade process the following error related to system storage is generated:

{master:0}
root> request chassis device-mode satellite /tmp/satellite-X-signed.tgz
Fetching package...
Extracting image /var/tmp/sd-install.tgz
Metatags extracted
Satellite package version is ‘X’
error: The /var/tmp filesystem is low on free disk space. This package requires 1M more free space. Please remove archived files and unused satellite images using 'request system storage cleanup' and 'request system software delete version' commands.

To resolve the issue, follow these steps:

1.    Upgrade QFX5100 or EX4300 with SNOS Package:

• Ensure the QFX5100 or EX4300 switches are upgraded to the corresponding JUNOS X before attempting the upgrade SNOS X upgrade.

2.    Disable Cascade Port:

• Disable the link to the aggregate.

3.    Clear System Storage:

• Use the following commands to clear system storage

request system storage cleanup
request system software delete version

4.    Copy Image to /tmp and Upgrade:

• Copy the SNOS image to the /tmp directory and proceed with the upgrade:

request chassis device-mode satellite /tmp/satellite-X-signed.tgz

Following these steps will ensure the successful installation of SNOS on QFX5k or EX4300 switches before adding these to the Fusion fabric.
