When I went to change some settings for PLEX Media Server today (Phaze plugin) It came up as not installed and not running, as well as having default install location (the flash drive instead of my cache drive), like it was a fresh install that needed setting up and starting. I accessed the flash drive from the finder via SMB (I'm on OS X) and the flash drive shows as empty. Everything is acting as expected, however. My Plex clients can all see the PMS and UnRAID is chugging along as expected. Any idea what's going on here? I think I just probably need to restart the server and see where that gets me, but I'm in the middle of a fairly large data transfer, and prefer to wait until that's finished. While I'm waiting I thought to check with the hive mind here to see if  there's something else i should do. Thanks for your inout.

Sounds like your flash is corrupt or dead. unRAID can run without until reboot as long as you don't need to save anything like plugins or config changes. Go ahead and finish the transfer then checkdisk in your pc.

Is this something that can be done on OS X? Sorry, no PC available currently.

Use Disk Utility on the Mac to repair the flash.

Thanks. That's what I thought, but wanted to be sure.

Well, It turns out I was not able to shut down the array properly from the web GUI or via command line, so I had to pull the plug. Restarted and everything came up normally. The flash drive did not show any chkdsk errors. Not sure what happened.

If it happens again, check your syslog.  You're probably going to see a whack of "BREAD" errors in it.

 

These problems are caused by one of two things - a bad flash drive - or a bad port.  Sometimes the problem can go away if you use a USB2 port instead of a USB3 port for the flash drive.

Thanks for the tip. The flash is on a USB 2.0 slot directly on the motherboard. I'll check the syslog, if it ever happens again. I am not really a Linux person, so logs are all greek to me, but I can always get some help here.

On my one server, I had disable the USB3 ports in order for this problem to go away (I don't use SNAP / external USB drives so it wasn't a big deal for me)

Funny you mention that - I tried to plug in an external HD for the first time ever and then, sometime later, I noticed that emhttp had hung.

 

I'm pretty sure my motherboard (SuperMicro X8SIL) is too old to have USB 3.0, but I've been wrong before.
