We are planning upgrade our devices (5600) from R80.20 to R81
Based on documentation for upgrade process we'll need at least 20G free space in root and 10G free space in /var/log.
The point is that we don't have it and we'll have to delete some files.
Our current situation (df -k):
| root available | /var/log available |
cpgw1 | 20625344 | 40789092 |
| | |
cpgw2 | 18774856 | 52872796 |
| | |
cpmgmt | 11060268 | 6061220 |
And with LVM Manager Storage overview in attachment.
Until now I didn't have issues with free space during upgrades but here they comes and I don't want to end up with deleting something important. It's production HA ClusterXL and I'm not expecting some issues during upgrade process (one by one with CPUSE) but need to make sure that the process will start at first place.
In attachment I've extract all files in / with size of +10000 using following command:
find / -type f -size +10000 -exec ls -lh {} \; 2> /dev/null | awk '{ print $NF ": " $5 }' | sort -nk 2,2
Can I get advice which files will be save to delete in order to free up some space?
I will really appreciate it.
Thanks in advanced,
