EVE-NG free space issue after node image remove

Post by hasan_28 » Mon Aug 05, 2019 9:37 am

Hi Admin,

I am getting one wired issue - when I delete one node image like juniper QFX RE/PFE etc. from /opt/unetlab/addons/qemu/ folder, free space is not showing at all. May be I am missing something.
Appreciate if someone can help how to free up the space. Otherwise I need to delete the VM and rebuilt it.

Thanks

hi UD,

Thanks for your quick reply. Yes there is a directory under /opt/unetlab/tmp/ and it contained almost 40Gb data. After removing that folder I can see my overall VM size is 83Gb but VMDK file size did not reduced. This is showing 122Gb excluding temporary file 25Gb.

root@eve-ng:/# df -h

Reinstall EVE, and assign normally HDD..
Do backup of eve and install new, from ISO

Procedure to Backup content of EVE-PRO
For backup EVE content copy following folders:
/opt/unetlab/addons/
/opt/unetlab/tmp/
/opt/unetlab/labs/

Install EVE From ISO

Update - guys, DON'T DELETE that /opt/unetlab/tmp/0/ folder, it contains all your configs for devices in topology.

Correction,
opt/unetlab/tmp/0/
contains your saings of the labs!

Labs itself will survive, but if to delete this folder content all savings what you did on lab nodes will be lost
But freed space of hdd :)
