<p class="MsoNormal"><span lang="EN-US"> Lately, we meet a glusterfs split brain problem in our env in /mnt/export/testdir. We start 3 ior process (IOR tool) from non-sn nodes, which is creating/removing files repeatedly in testdir. then we reboot sn
nodes(sn0 and sn1) by sequence. Then we meet following problem.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> Do you have some comments on how this could happen? And how to fix it in this situation? Thanks!<o:p></o:p></span></p>
