Hi, I'm new to Unraid and still testing it out. I have rebooted my 3 drive test array about 3 times now and everytime I reboot my two disk drives are marked with a green circle and my parity drive is marked with blue. My understanding is that blue means the drive is new to the array. When I start the array the system starts doing a parity sync and it says the array won't be valid unless I let the parity sync run it's course. My sync takes about 12-15 hours. Is this supposed to happen? Will I have to parity sync after every reboot?

 

I also tried putting the server to sleep and when I woke it back the system seemed to be completely haywire. It said I had the wrong drive in disk1 slot. The seriel number of the expected drive and the actual drive were the same but the system said the size of the drive should have been 1.5PB rather than 1.5TB. I couldn't figure what to do so I restarted and it started on the parity sync again. Any insight would be helpful. Not sure what's going on. I'm about ready to buy a pro license but need to make sure things are running properly first. Thanks

How are you restarting? Only use the web GUI or install the powerdown script.

Not sure what the powerdown script is but I do use the webgui to restart. I'm doing the parity sync right now so in about twelve hours I'm going to shutdown and try it again. Hoping there were just minor glitches from before. So on reboot, the parity drive should still be green right?

 

Thanks for helping and assisting in my issues. I really appreciate it!

If the parity build completes before the reboot.

So if I shut down by any other means besides using the webgui and the main console, will this forced parity sync happen?

Yes; and it may cause file system problems. Only use the unRAID web GUI.

 

The powerdown script add-on will allow a clean shutdown from the command line and should allow the power button to be used for a clean shutdown. Search for unmenu in the User Customizations forum.

I have unmenu installed. Although there's so much stuff about it I'm not sure what to do with it. Managed to get SNAP kind of working. So I need to add a script to get it to shutdown from command line but GUI is always ok?

 

So what happens in the event of a power outage? If parity errors out and has to be re-synced on a power outage that would be really bad because that would be a situation where a drive may likely fail also.

A UPS is very important for a stable data storage system.

 

Always use the unRAID web GUI to shutdown. (Unless the powerdown add-on is installed.)

If you had a UPS hooked up to the Unraid Server and the power went out you would pretty much need the powerdown add-on installed to shut the server down, right? Otherwise, you would need power available to the router/switch and another PC in order for you to shutdown via web Gui. I guess I better go read up on how to install the powerdown add-on. Thanks for the advice.

Yes. The apcupsd package is also required.
