Description

Hi!
We've just installed lustre 2.13.0, to set io500 test.
System contains 2 MDS (4MDT) and 12 OSS (24OST).
mpirun used on 49 client nodes. 
For ior_hard test overstripe was set like this:

lfs setstripe -C $((24*5)) -S 16M $io500_ior_hard 

This test failed with such errors:
ior ERROR: open64("/lustre/stor1/rsc/io500/2020-spring/io500.2020.05.15-01.57.48/ior_hard/IOR_file", 66, 0664) failed, errno 95, Operation not supported (aiori-POSIX.c:413)

Maybe we've missed something. 

Regards
