Hi, We are facing the same issue : we just upgrade our cluster to GPFS 4.2.3-9 and RHEL 7.5 with 4 gateways servers executing Kernel NFS... => random "Unknown error 521" on NFS clients.
Thanks to this thread we decided to downgrade to RHEL 7.4 and (fingers crossed !) up to now, it seems to work properly. Is there any official recommendation from IBM on this problem ?

So it's probably just GPFS not being ready for 7.5 yet. Neil. Neil Wilson? Senior IT Practitioner Storage, Virtualisation and Mainframe Team??

I am also under the impression that kernel NFS was not supported either it's Ganesha or nothing. The interim fix is probably to downgrade to a 7.4 kernel. Certainly in the past that has worked for me. JAB. -- Jonathan A.
