Hi,



I?m running 6.2u3.



I tried to find compute hosts using the qhost command.

But it seems that qhost failed to recognize the node in the exclusive mode.



$qhost -l excl=false

HOSTNAME                ARCH         NCPU  LOAD  MEMTOT  MEMUSE  SWAPTO  SWAPUS

-------------------------------------------------------------------------------

compute-0-0             lx24-amd64      4  0.00    3.9G  706.7M    4.0G  172.0K



$qhost -l excl=true



Nothing appeared although I have an exclusive job running on compute-0-1 host.



$qstat -F excl

queuename                      qtype resv/used/tot. load_avg arch          states

---------------------------------------------------------------------------------

normal at compute-0-0.local       BIP   0/0/2          0.01     lx24-amd64

        hc:exclusive=1.000000

---------------------------------------------------------------------------------

normal at compute-0-1.local       BIP   0/1/2          0.03     lx24-amd64

        hc:exclusive=0.000000

    195 1.10000 sleep      ch21778      r     09/24/2009 16:02:25     1



$qconf -sc |grep excl

exclusive           excl       BOOL        EXCL    YES         YES        0        1000



If I?m not running any exclusive jobs on the cluster, it lists all nodes with the ?l excl=true flag:



$ qhost -l excl=true

HOSTNAME                ARCH         NCPU  LOAD  MEMTOT  MEMUSE  SWAPTO  SWAPUS

-------------------------------------------------------------------------------

compute-0-0             lx24-amd64      4  0.00    3.9G  705.5M    4.0G  172.0K

compute-0-1             lx24-amd64      4  0.02    3.9G  655.7M    4.0G  104.0K



$ qhost -l excl=false

HOSTNAME                ARCH         NCPU  LOAD  MEMTOT  MEMUSE  SWAPTO  SWAPUS

-------------------------------------------------------------------------------

compute-0-0             lx24-amd64      4  0.00    3.9G  705.5M    4.0G  172.0K

compute-0-1             lx24-amd64      4  0.02    3.9G  655.7M    4.0G  104.0K





Is this a known bug?



Thanks,
