[gpfsug-discuss] CES: ldap_down event

[Oesterlin, Robert]

Simply restarting mmsysmon “mmsysmoncontrol restart” cleared the error – so I’m back to my basic question – why did this not clear on its own?

We’re not using LDAP for SMB, we’re using it for NFS – so gpfs.windbind isn’t active. As for the state of things:

[root at nrg-ces01 ~]# mmces state show -a
NODE                                AUTH       BLOCK      NETWORK   AUTH_OBJ   NFS        OBJ        SMB        CES
xxxxxxxxx.xxxx.us.grid.nuance.com   DEGRADED   DISABLED   HEALTHY   DISABLED   DEGRADED   DISABLED   DISABLED   DEGRADED
yyyyyyyyy.yyyy.us.grid.nuance.com   HEALTHY    DISABLED   HEALTHY   DISABLED   HEALTHY    DISABLED   DISABLED   HEALTHY

NFS is showing degraded because AUTH is degraded due to the LDAP error. However, I think the error is erroneous because the NFS service on that node is fine.

You can either reboot that node, or try:

# systemctl restart gpfs-winbind.service
# systemctl status gpfs-winbind.service

The LDAP server was found unresponsive at some point.  Why, that’s the million dollar question as always.

What’s the output of ‘mmces state show -a’ look like?

Thanks,
Will

What caused this error, and how do clear this error? The LDAP server is fine as far as I can tell…

Scale version 5.0.1-2
