-28 = -ENOSPC. Is there enough space on the OST for your test?

[James A Simmons]

Currently for my 28 OSTs I have the size set to

OSTSIZE=${OSTSIZE:-1600000}

Mind you I'm using 35 clients during these test.

[James A Simmons]

Okay I used the full disk size, 7TB, and the test passed.

Workaround found so closing
