GridEngine Users,
I'm having the following recurring problem with my GridEngine
installation. The problem started last week. Users reported to me
that the qrsh command wasn't working. What happens is that after
running qrsh from the login node, there is a pause and then you get a
prompt on the login node again, instead of the prompt for an
execution host, like this:
[xxxx@login ~]$ qrsh
[xxxx@login ~]$
This seems to be dependent on the execution host assigned to the
task, and I've determined which hosts are the problems. For example,
if I shutdown the problematic hosts, qrsh works:
[xxxx@login ~]$ qrsh
[xxxx@c9n3 ~]$
After one of these qrsh jobs fails, I get the following e-mail:
Job 5326173 caused action: Job 5326173 set to ERROR
User = xxxx
Queue [email protected]
Start Time = <unknown>
End Time = <unknown>
failed assumedly before job:can't get password entry for user "xxxx".
Either the user does not exist or NIS error!
This error indicates there's something wrong with getting user
information. However, I can ssh into the problematic execution hosts
just fine, and when I do a 'getent passwd <username>', I get the
correct results. I've gone over my PAM configuration, and
my /etc/nsswitch.conf configuration, but I don't see anything
obviously wrong. It appears to me that sge_execd is using some other
mechanism for getting user information that is not configured
correctly on these hosts.
Any ideas as to what could be wrong? Any suggestions on how to debug
this?
Are you running nscd on your system? In the past we've had issues
with nscd getting confused and needing a good kicking.
William,
This problem is definitely consistent with a wonky nscd, but I'm using
sssd instead of nscd on these systems.
