Hi,

We have configured a shadow host for our existing SGE cluster.

But when the qmaster service is killed, the shadow host doesn?t take up the qmaster?s job.

It doesn?t show any error in the spool directory.

The following are the list of services running on master and shadow host.

Master host:

root       426     1 0 May20 ?        00:00:00 /opt/sge/bin/lx24-amd64/sge_shadowd
root     31636     1  0 13:16 ?        00:00:00 /opt/sge/bin/lx24-amd64/sge_qmaster
root     31655     1  0 13:16 ?        00:00:00 /opt/sge/bin/lx24-amd64/sge_schedd

Shadow host:
root     21632     1 0 04:44 ?        00:00:00 /opt/sge/bin/lx24-amd64/sge_shadowd

Both the master and shadow host are NFS mounted.

Whether the shadow host also needs to run the qmaster and schedd service? Please help me in configuring shadow host.

As per my understanding, only shadowd service should run on the shadow host.

Kindly let me know whether my understanding is correct.

Thanks,
Thamizh
