/usr taking up disk space after upgrade

Hi everyone,

 

After upgrading our BIG-IP 1600 systems to 10.2.4.-HF5 we have noticed that /usr partition is at 80% of disk space occupation.

 

[root@xxxxxxxxxxxx:Standby] share df -kh

However the i-nodes occupation for the same partition shows a much lower figure

 

[root@xxxxxxxxxxx:Standby] share df -i

Is this related to the fact of having two software images loaded in the system?, is the new load "heavier" that the previous one?

 

How can we find which files can be safely removed or stored off-line?.

 

Thanks
