I am trying to preclear a new parity drive, it is larger than my current parity and I do not have any room in my server so I have downloaded unraid onto a new usb key and booted in a spare machine with the new parity drive in it.

 

I copies preclear_disk.sh onto my flash drive, and unraid see my disk and it is unassigned but when I try to run preclear it says:

 

line 202: /boot/config/disk.cfg: No such file or directory 

 

Same message if I run preclear_disk.sh -l 

 

What am I doing wrong?  I thought I could boot up a fresh copy of unraid and preclear with it?  How do I get this drive cleared and ready for parity swap?

Try doing a new config and see if that creates the disk.cfg file for you.  Preclear needs to read the disk.cfg file and is complaining it doesn't exist.  If that doesn't work you could try to copy the disk.cfg file from your existing array to the new flash drive make sure you put it in correct directory like displayed above.  Then do the new config.  Now try your preclear again.

I'm not sure how to do a new config, so I copies the config file from my registered server and the drive is now listed when I run preclear_disk.sh -l

 

However, when I run the preclear command, it now says:

 

Sorry:  Device /dev/sdb is busy. : 1

 

I restarted the server, same message.  The disk is not assigned to the array.

 

That means you did not convert the preclear script to be V6 unraid compatible.  Try the attached file.

preclear_disk.sh

 

Just realized that is bjp999's version if you want the -F option to work you will need this file too

That worked, thank you!  Drive is happily preclearing now.  Boy 10tb drive us going to take some time!  

 

 

Yep.  I only have 8TB drives but they took 120 hours for my normal 3 cycles - even with the faster post read the script above provides and only 8TB.
