errno 521 is EBADHANDLE (a Linux NFS error); it is not from spectrum scale.
/* Defined for the NFSv3 protocol */
#define EBADHANDLE 521 /* Illegal NFS file handle */

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 ?
Regards,
PM

We are running a cNFS on GPFS 4.2.3-9 on 7.4 and kernel version
3.10.0-693.21.1.el7.x86_64 and are not having any errors.
So it's probably just GPFS not being ready for 7.5 yet.

GPFS being not supported on 7.5 at this time would be the starting point. 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.
