<p class="MsoNormal">Limiting the feature flags to those used in R151006 will eliminate the eager zero panic bug currently present in versions R151010 and later including the current LTS R151014.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Example:</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">zpool create -d \</p>
<p class="MsoNormal">-o feature@async_destroy=enabled \</p>
<p class="MsoNormal">-o feature@empty_bpobj=enabled \</p>
<p class="MsoNormal">-o feature@lz4_compress=enabled \</p>
<p class="MsoNormal">poolname \</p>
<p class="MsoNormal">raidz3 %disks% \</p>
<p class="MsoNormal">raidz3 %disks% \</p>
<p class="MsoNormal"><....></p>
<p class="MsoNormal">log mirror %disks% \</p>
<p class="MsoNormal">cache %disks%</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Also in an unrelated hint. Disabling the write back cache in the fibre target will prevent corrupted VMs that might otherwise result from a panic.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">PS. Be sure to have an SSD backed log mirror to minimize the write performance impact.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Example:</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">stmfadm modify-lu -p wcd=true <Lun Number here></p>
