[gpfsug-discuss] mmapplypolicy - listing policy gets occasionally get stuck.

Hi All, We are occasionally seeing an issue where an mmapplypolicy list job gets stuck , all its doing is generating a listing from a fileset. The problem occurs intermittently and doesn't seem to show any particular pattern ( i.e. not always on the same fileset) The policy job shows the usual o

Re: [gpfsug-discuss] CES-NFS: UID and GID resolution

I think it’s caused by the ID mapping not being configured properly. Found this on the redhat knowledge base. Environment * Red Hat Enterprise Linux 5 * Red Hat Enterprise Linux 6 * Red Hat Enterprise Linux 7 * NFSv4 share being exported from an NFSv4 capable NFS server Issue

Re: [gpfsug-discuss] GPFS 4.2.3-9 and RHEL 7.5

We are running a cNFS on GPFS 4.2.3-9 on 7.4 and kernel version 3.10.0-693.21.1.el7.x86_64 and are not having any errors. So it's probably just GPFS not being ready for 7.5 yet. Neil. Neil Wilson  Senior IT Practitioner Storage, Virtualisation and Mainframe Team   IT Services Met Office FitzRoy

Re: [gpfsug-discuss] Problem with the gpfsgui - separate networks for daemon and admin

Hi Matthias, Not sure if this will help but we had a very similar issue with the GUI not showing performance data, like you we have separate networks for the gpfs data traffic and management/admin traffic. For some reason when we put the full FQDN of the node into the "hostname" field (it's bl

[gpfsug-discuss] ZIMON Sensors config files...

Hi, Does anyone know how to use "mmperfmon config update" to get the "hostname =" field in the ZImonSensors.cfg file populated with the hostname of the node that it's been installed on? By default the field is empty and for some reason on our cluster it doesn't transmit any metrics unless we pu

Re: [gpfsug-discuss] AFM from generic NFS share - mmafmconfig

I think you need to configure a gateway node (use mmchnode to change an existing node class to gateway) Then use mmafmconfig to setup export server maps on the gateway node. e.g. mmafmconfig -add "mapping1" -export-map "nfsServerIP"/"GatewayNode" (double quotes not required) mafmconfig show al

Re: [gpfsug-discuss] AFM Prefetch Missing Files

We recently migrated several hundred TB from an Isilon cluster to our GPFS cluster using AFM using NFS gateways mostly using 4.2.2.2 , the main thing we noticed was that it would not migrate empty directories - we worked around the issue by getting a list of the missing directories and running i

[gpfsug-discuss] GPFS GUI

Hello all, Does anyone have any experience with troubleshooting the new GPFS GUI? I've got it up and running but have a few weird problems with it... Maybe someone can help or point me in the right direction? 1. It keeps generating an alert saying that the cluster is down, when it isn't??
