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.

Hello,
In my experience, this problem is often due to "/tmp" being 100% full.

It appears GPFS 4.1.1 now displays a meaningful message in such a case:
 # df -h /tmp | grep %
                       985M  985M     0 100% /tmp
 # /usr/lpp/mmfs/bin/mmgetstate
mmgetstate: Unable to obtain the OS name. The tmp file system may be full.
