    Thanks for taking a look at this.
    I thought I read on the 23/3400s. Juons wants 3 or 4 times the size of the installer in free space  and the 4300s installer is 250M.. 
    Does anyone know the needed amount of free space Junos looks for to do an install ? 
    If its like the 2300s in the past ive had to use the unlink no-copy force options to squeeze it into the limited space on the boxes..

    Here is my info.
    As you can see /var/tmp has 725M free.  
    Filesystem Size Used Avail Capacity Mounted on
    /dev/da0s3e 170M 10M 146M 7% /var
    /dev/md25 252M 249M -18M 108% /tmp    **Freebsd os is doing the fs reserve on the /tmp partition so as you the -18M where i have stored the .tgz
    /dev/da0s3d 887M 92M 725M 11% /var/tmp

    The /var/tmp filesystem on JUNOS is low on free disk space.

    Extracted the .tgz and see in the +INSTALL file some basic info about some requirements for the 4300 install.

    Here is part about RAM
    # minumum recommended memory size in MB.
    recommended_memsize=512
    # Lowest threshold memory size: equal or below 256MB size is not allowed.
    min_memsize=268435456

    Found what I think is the disk size retirement.  This may be something Juniper needs to tweak as the newer image size are getting larger of course.

    # suggested = space needed by pkg_add playpen. Playpen size is two times the size of the package.

    I did get the installer to work  doing the storage cleanup and then jumping to the cli as root and cleaning up all my logs by doing a cat /dev/null > cosd for an example.. and the install syntax
    request sys soft ad /tmp/jinstall-ex-4300-20.2R1-S3.2-signed.tgz no-copy unlink

    Running on 2 4300-24p sites  right now on 20.2 ..

    I haven't installed 20.x in an EX4300 yet (should do that in my lab units...) but I rarely bump into problems with the EX4300 and disk space. The 2300 and 3400 is another matter. If you have access to the boxes you could try a USB install, or do it via ftp/sftp/tftp. What is the current version?

    I know right , first time ever with a disk space issue with the 4300s. My guess it was a rush out to address the CVEs  and
    the +INSTALL was not updated to address the size of the installer.

    The version was 19.4R? 
    I got it to install on my test the waters stack vai the method I posted to the thread about..
