showq shows less active nodes as normal
I am new in system administration. I observe that some nodes in our cluster
are not considered as active by showq:
22 active jobs 217 of 257 processors in use by local jobs (84.44%)
15 of 17 nodes active (88.24%)
but then I try to log into each of the nodes by ssh and they are working,
well at least I can log in.
Is there any command to know what is happening with the nodes
besides showq? I have tried
pbsnodes and it shows some nodes as exclusive and the others as free but none of
them as down.
We are running:
Red Hat Enterprise Linux Workstation release 6.1 of 64 bit.
