In the message dated: Tue, 12 Jan 2016 11:24:18 -0800, The pithy ruminations from Yuri L Volobuev on <Re: [gpfsug-discuss] weird issue when issuing mm commands> were: => => GPFS code determines the current OS by looking at the output of "uname -s". => On a regular Linux node, this command returns "Linux", so check whether you
I saw the same issue on several Scientific Linux release 6.7 machines last week. These machines have been GPFS clients since ~ SL 6.3 & GPFS 3.5.9 (~3 years). This error never happened previously. Various 'mm*' commands were returning the "Unknown OS" error. Note that there was no OS named at the end of the error message, as if $osName was not defined in /usr/lpp/mmfs/bin/mmglobfuncs. The 'uname -s' command on these nodes does return "Linux" both locally and remotely via an ssh connection from a GPFS manager node. Updating OS distribution packages & rebooting the nodes & rebuilding the kernel-specific gpfs.gplbin packge resolved the problem, so I'm not sure of the exact cause. Mark => see the same, when the command is run locally on the node and through an => ssh session. Since mmaddnode has to do some remote processing, make sure => ssh works as expected, in particular in the locale setting area. => => yuri => => => => From: Damir Krstic <[email protected]> => To: [email protected], => Date: 01/12/2016 06:16 AM => Subject: [gpfsug-discuss] weird issue when issuing mm commands => Sent by: [email protected] => => => => I have just deployed a GPU node in our HPC environment and I am having => couple of weird issues when trying to add it to our GPFS cluster. mmaddnode => command from NSD server returns with: unknown os => => mmgetstate on the node itself returns with unknown os => => I think I've traced it down to locale issue but reinstalling glibc-common => and making sure that /etc/sysconfig/i18n files are in place and OK does not => seem to fix the issue.
