I installed the screen add-on, and ran it is my DOS command prompt. 

 

I then started a pre-clear on a hard drive.  At some point there must have been a network blip, my DOS window reported a lost connection, and exited out of the pre-clear process.

 

Because I used "Screen", is my pre-clear still running, or has it been halted and I should re-start it?

It should be running.

 

If you login again and use

screen -x

then it should reconnect to the screen session if it is still running.

You can find out by going into umenu then mymain - find the drive you were preclearing - should have the last known state of drive or last state of preclear before it was interrupted. make note of percentage done and time, refresh in a couple of minutes to see if the progress has changed.  If it does not change then you'll have to restart the preclear process.

I will do both suggestions, thank you!

 

Worst case I re-start the pre-clear, I just wanted to understand more about screen, and now unmenu, thanks again.

Yes, I can see under "mymain" that it is now doing the post-clear, so it is still running the pre-clear even though my command prompt lost connection to host.

 

Thank you!

That's why it's important to use Screen when you're not doing pre-clears at the actual UnRAID console.

 

If you do it via Telnet, the pre-clear process will be shut down when you exit the Telnet session => and leaving a Telnet session open for the MANY hours a pre-clear takes on large drives is obviously not a desirable thing [and it's "oh so easy" to accidentially close the window].

 

[and it's "oh so easy" to accidentially close the window].

 

Or for your workstation to go to sleep, install updates and reboot, encounter a network hiccup, etc.

It is very cool, I was able to login again and see my pre-clear in progress, as well as see it through un-menu.
