Freeing up space on a node’s root volume (vol0) ONTAP 9.1

[JSAR]

The root aggregate alert on 95% used space , how can i clean some space or Increase size , please note that i do not have any core dump files  or *.trc files to delete . The autosize mode is off as well.

Many thanks for the support.

Which is alerting aggr or volume?    The root aggr is showing 95% because the root vol is set to thick.  This is normal.   

If the volume is alerting that you are 95% free,  I would first check to see how many ONTAP install packages you have saved.   

cluster package image show 

system image package show

Did you check and see how many install images you have?     Those can add up.
