Storage issues on Juniper Networks QFX5120 | unable to copy file to switch
You can apply the following steps:
root@juniper> request system storage cleanup all-members
Delete the snapshot on all members:
root@juniper> request system snapshot delete * all-members
Storage cleanup will only remove files from the following directories:
/var/tmp
/var/log
/var/sw
/var/crash
Check for residual packages from old codes in the /packages/db/ directory and manually delete them.
Note: This is needed for each member.
Example: The current version this device is running is 181_r3_s4 and the previous version was: 151_x53_d59 (this is just an example of what you have to do with yours)
root@juniper> start shell user root

Delete old files using the following command:
root@juniper% rm -R [filename]
Example:
root@juniper% rm -R junos-arm-32-15.1X53-D59.4
root@juniper% rm -R junos-dp-crypto-support-mtx-arm-32-20180914.204810_builder_junos_151_x53_d59
If you don’t have any large size file in /var and the you still have high utilization then it may be because of the memory bloating. In that case a power cycle of device can help to bring the /var utilization down.
