lnet-selftest: Newly added "off" parameter no longer working

Bug Minor Open Unresolved Amir Shehata Doug Oucharek Fri, 26 May 2017 21:14:19 +0000 Mon, 26 Jun 2017 22:02:22 +0000 0 1 <p>Looks like this problem has been there since the beginning of this new parameter.  When you use a bulk size of 1M and apply an offset (i.e. "off=64), the system will need 257 fragments which is greater than the max allowed of 256.  </p> <p>The workaround is to use a smaller size (i.e. "size=512K").  It would be good if lnet-selftest allows for 257 fragments as the max to accommodate the offset parameter.</p> <p>I'm leaving this ticket open to do just that, but lowering the priority to minor.</p> Blocker LU-9500 Development Rank 1|hzzdp3: Rank (Obsolete) 9223372036854775807 Severity
