All, The SMAP issue has been addressed in GPFS in 4.2.1.1.
See http://www.ibm.com/support/knowledgecenter/STXKQY/gpfsclustersfaq.html Q2.4.

Sent by: [email protected] I don't know if this applies her but I seem to recall an issue with CentOS 7 (newer 3.X and on kernels), Broadwell processors and GPFS where GPFS upset SMAP and would eventually get the node expelled. I think this may be fixed in newer GPFS releases but the fix is to boot the kernel with the nosmap parameter. Might be worth a try. I'm not clear on whether SMAP is supported by the Xeon Phi's. -Aaron On Wed, Dec 7, 2016 at 5:34 AM <[email protected]> wrote: IBM says it should work ok, we are not so sure. We had node expels that stopped when we turned off gpfs on that node.
