Hi

I'm trying to preclear 3  2tb drives.

I've installed screen as per the manual but I'm a bit confused about the step that says:

Step 1 Open a telnet session to your UnRAID server and login as root

 

Does this mean I can use putty to open a telnet session?

Also, if my network drops does the preclearing carry on? If so, how do I see it's progress?

I'm guessing that I just open up a new putty/telent window and type screen -r

Is that right?

 

Thanks for any help

 

You should definitely follow the unRAID Configuration Tutorial.

 

Yes, use Putty to connect via Telnet to your server.

You start Screen with just "screen".  You reconnect to a screen session later on with "screen -r".

Screen will keep running on your server even if Putty disconnects, which is the main reason for using it.

It's also helpful to note that "CTRL-A c" creates another telnet prompt so you can run multiple pre-clears at the same time, that "CTRL-A n" cycles through screen telnet prompts, and "CTRL-A d" disconnects from your screen session while leaving it running.

many thanks for that.

Actually Ive got 3 putty windows open to preclear 3 drives. I suppose its the same thing .

No, its not!  If you drop any of those windows, that preclear will be aborted.  with screen, it will continue.

sorry i should have been clearer.

I'm running screen in each putty telnet  window

That's not how it's intended to be used, but you should be Ok.  You now have multiple instances of screen running and it's a little harder to reconnect.  If you type screen -r you may get something like:

 

There are several suitable screens on:

31917.pts-5.office      (Detached)

31844.pts-0.office      (Detached)

Type "screen [-d] -r [pid.]tty.host" to resume one of them.

 

Then you'd type "screen -r  31844.pts-0.office" to reconnect to the specific instance.

thanks thats very helpful

Tab completion is VERY helpful here, you really only have to type screen -r 318<TAB> and it will fill in the rest. I find myself reflexively hitting the tab key after the first couple characters for long command line paths and items, and it almost always saves a bunch of typing.

How to use screen to preclear.  Look at step 6.
