Just setup my first unRAID server and found everything easy to configuar.

But just one question to clarify my thoughts. 

Any time power is removed from the server, the Parity-Sync / Data-Rebuild has to run????

And it is not advisable to use the server while that is taking place???

The reason I ask is because it takes over 24 hours to run the Parity-Sync and that means the server shouldn't be used for 24 hours???

I live where power is not super stable and even with UPS backups we will power down un-needed systems. 

Thank you 

If you're pulling the plug while it's on, that's an unclean shutdown. So, yes, it will run a parity sync to detect possible file corruption.

 

If you're powering it down normally, that's a clean shut down. If you unplug after it's off, then no, it won't run parity sync.

Thanks for the quick response.

After posting I did read the UPS section of the settings.
