Try to update JunOS SRX240H from 11.4R7.5 to 11.4R10.3, but found storage space is not enough and to hold the JUNOS even after request to clean the storage on the device. There is one way to use external USB key to do upgrade, as described from previous post Upgrade Juniper JUNOS on SRX using USB Storage
However, this time the storage is only short about 15M to hold this 11.4R10.3 package. There should have a better way to deal with it.

I am wondering why Node1 is 30M less free space than Node0.
Using find command we could find out which file is having bigger size.
