root@glogin ~ # xrdfs glogin:1095 locate -m /data
glogin.iup.uni-bremen.de:1095 Server Read
yes, i know 4.10.0 is old. But it is still operational and we dont need
the bleeding edge features of the new releases.
Also i know that i can retrieve the information from the cmsd.log file,
but it would be more helpful in daily operations to get these via a
command directly without searching the logs.
Ok, to turn the qeustion around:
How can i determine a dead node with xrd tools ?
Regards
Heiko
