<p class="MsoNormal">If the local and remote sites have good inter-site network bandwidth and low-latency, then you may consider using GPFS synchronous replication at the file-system level (-m 2 -r 2). The Spectrum Scale documentation (link below) has further
details. <o:p></o:p></p>

<p class="MsoNormal">we are trying to implement a mixed linux/windows environment and we have one thing at the top - is there any global method to avoid asynchronous I/O and write everything in synchronous mode?<o:p></o:p></p>

<p class="MsoNormal">Another thing is - if there is no global sync setting, how to enforce sync i/o from linux/windows client?<o:p></o:p></p>
