calculation directory size faster

[oberon11]

hi everyone,

I have been working on this for a bit but can't seem to get it working faster. I am calculating Directory sizes on multiple servers using du but it scans all the sub directories but that takes forever would someone have an Idea to make it go faster or maybe have some sort of precalculation coding?

thank you

Well you can run du parallel on eatch server via ssh.

i wrote this script for it once.

RUN:
[lbl@atom0 ~]$ ./xserv-admin cmd "du -ch /tmp | tail -n 1" 2> /dev/null
Server Admin tool
==> Running "du -ch /tmp | tail -n 1" on atom0 <==
==> Running "du -ch /tmp | tail -n 1" on atom1 <==
==> Running "du -ch /tmp | tail -n 1" on sip <==
sip: 48K total
atom1: 658K total
atom0: 60K total
All commands are done.
[lbl@atom0 ~]$


Script:
#!/usr/local/bin/bash

echo "Server Admin tool"

#Systems in the tool
systems="atom0 atom1 sip"

sshcommand()
{

for i in $systems
do
echo "==> Running \"$1\" on $i <=="
ssh $i "$1" | sed "s/^/$i: /" &
done
}

case "$1" in
'loggedin')
sshcommand "w"
wait ; echo "All commands are done."
;;
'cmd')
sshcommand "$2"
wait ; echo "All commands are done."
;;
*)
echo "Usage: $0 loggedin"
echo "Usage: $0 cmd <command to run on remote systems>"
;;
esac

A nice tool for checking stuff out if you have a shitload of servers.

This wont help "du"´s speed tho ... hehe
