<p class="MsoNormal">Over the past few weeks, I have had 3 separate occurrences where my OmniOS/Napp-it NAS stops responding to NFS and CIFS. The first time was during the week of the ZFS corruption bug announcement. The system and it’s replicated storage
were both scrubbed and zdb analyzed, and nothing looked wrong. I rebuilt the NAS from scratch with updated patches and imported the pool. Same thing happened three days later, and now today, eight days later. Each time, a reboot is performed to bring it
back. All services appear to be running. The odd thing is that an “ls –l” hangs on every mountpoint. Has anyone heard of this issue? Since I am not OmniOS savvy, is there anything I can capture while in that state that could help debug it?<u></u><u></u></p>
