Troubleshooting help needed: Server goes unresponsive.

[Geeksareus]

I inherited this system a year and a half ago. I have learned a ton since then, but still I feel like a novice. I have a 2 in 1 custom built unit that has openindiana/napp-it on one side and esxi with windows server and active directory on the other. I have four setups like this and three of them seem to work without much difficulty. But one is giving me fits and goes unresponsive randomly. I am unable to access it through ssh and webgui. All SMB and NFS stores don't show up and the unit requires a reboot to get everything back up and running.
Where do I look first to start the troubleshooting process?

I would first check for a bad disk, cabling or backplane problem.

- napp-it menu system > log or system > fault or menu pool (soft, hard, transfer errors)
- napp-it menu disks > smartinfo > short smart check of disks

Here is the log from today (it failed today)

I did the smart check on the disks and it looks like one of them did come back as bad. Thanks for your help!

That's great.
