I'm curious to know why this doesn't affect GSS/ESS? Is it a feature of
the additional check-summing done on those platforms?

- TITLE: IBM Spectrum Scale (GPFS): RDMA-enabled network adapter failure
on the NSD server may result in file IO error
- URL:
http://www.ibm.com/support/docview.wss?uid=ssg1S1010233&myns=s033&mynp=OCSTXKQY&mynp=OCSWJ00&mync=E&cm_sp=s033-_-OCSTXKQY-OCSWJ00-_-E
- ABSTRACT: IBM has identified an issue with all IBM GPFS and IBM
Spectrum Scale versions where the NSD server is enabled to use RDMA for
file IO and the storage used in your GPFS cluster accessed via NSD
servers (not fully SAN accessible) includes anything other than IBM
Elastic Storage Server (ESS) or GPFS Storage Server (GSS); under these
conditions, when the RDMA-enabled network adapter fails, the issue may
result in undetected data corruption for file write or read operations.
