Hello all,
I am setting up a cluster that has been moved from one university to
another. I think i'm having Maui issues associated with the new
hostname. The cluster operates on SuSE Linux 10.2, using Torque 2.8
and Maui 3.2. I have made a number of necessary changes and performed
exhaustive searches through both maui and torque forums, to no avail.
I've also looked over the maui and torue manuals, and am now slowly
losing sanity. Any advice is appreciated. Here is what I did:
1) updated maui.cfg SERVERHOST
2) updated torque server_name and mom_priv/config
3) updated /etc/hosts on master
4) updated network configurations
5) reconfigured pbs_server with new acl_hosts = new_hostname
At this point, I can ping nodes from the master. I logged into one
node and change it's /etc/hosts so that I can now ping the master and
other nodes from this node (this is the node I am working with and
submitting jobs to, before i make any changes on other nodes). mom
logs also indicate good communication. My problem occurs when I submit
a job - it hangs in que. I can sudo qrun no problem. At first,
checkjob indicated the reason was:
job is deferred. Reason: RMFailure (job cannot be started - cannot
set hostlist)
I tried a few things that did not work:
-releasejob
-running maui in simulation mode, which returned: ERROR: cannot
open user interface socket on port 42559
- Tried to manually set hostlist in maui.cfg via ' SRHOSTLIST[27]
node2 node3 ...' keeping in mind that the default is ALL. This gives a
different checkjob error:
PE: 1.00 StartPriority: 1
job cannot run in partition DEFAULT (idle procs do not meet
requirements : 0 of 1 procs found)
idle procs: 36 feasible procs: 0

If I get rid of SRHOSTLIST[27] node2 node3... in maui.cfg, i get the
previous "RMFailure (job cannot be started - cannot set hostlist)".
Thus, for now, I am keeping this line active in maui.cfg so that I can
at least see job failure 'reasons'
Can anyone tell me why maui thinks all my nodes are overcommitted even
though I can for them to run with pbs?
Thanks in advance,
Enoch
