hi is that any command to find out which filesystems occupying more process in cpu utilisation
Interesting question.
I'd start with lsof.
meybe topass 
Maybe can try filemon :
filemon -o /tmp/filemon.out -P -T 60000000 -O all
sleep 30
trcstop
Later check out filemon.out
Hi,
first of all - a filesystem doesn't consume cpu - it might consume memory. Applications residing in a particular filesystem consume cpu - so find out which applications are the cpu consuments, than find out where they're located - ps, fileplace, nmon with c and u options can help.
Kind regards
