group - replication will not work.</font><br><br><font size=2 face="sans-serif">2) Do you have 2 Storage Systems ? When
using GPFS replication write stay the same - but read can be double - since
it read from 2 Storage systems</font><br><br><font size=2 face="sans-serif">Hope this help - what do you try to
achive , can you share your env setup ?<br></font><br><font size=1 face="Arial"> </font><p><font size=2 face="Arial">Regards</font><p><font size=1 face="Arial"> </font><p><table width=780 style="border-collapse:collapse;"><tr height=8><td width=780 colspan=4 style="border-style:none none none none;border-color:#000000;border-width:0px 0px 0px 0px;padding:0px 0px;"><div align=center><hr noshade></div><p><font size=1 face="Arial"> </font><tr height=8><td width=780 colspan=4 style="border-style:none none none none;border-color:#000000;border-width:0px 0px 0px 0px;padding:0px 0px;"><font size=1 face="Arial"> </font><tr height=8><td width=516 colspan=2 style="border-style:none none none none;border-color:#000000;border-width:0px 0px 0px 0px;padding:0px 0px;"><font size=2 color=blue face="Arial"><b>Yaron
