if you mean displayed as in "through the web interface" then you also have to move the ganglia frontend to that server or arrange for it to be able to read the RRD files from its filesystem (using NFS or any other kind of network file system). > I > confirm that there isn't any configuration error, just change the > working-dir of the rrd data. by this you mean : 1) shutdown gmetad 2) move directory with the RRDs somewhere else preserving permissions 3) update gmetad.conf's rrd_rootdir (better make a symbolic link and if not update conf.php's $gmetad_root as well) 4) start gmetad > ii.Today, I moved the rrd data from A server to B, because I was going > to change the role of some servers.

Now I couldn't got neither ganglia system running:( does the user that gmetad runs as write access to the directory where the RRDs are and execute permission to all directories before that starting from /? was the time modification from the files preserved when copied from system A to system B, and both systems have the same valid time?
