Unraid just runs and runs so I forget things (remember I just celebrated the 20th anniversary of my 52nd birthday)  I have 7 2TB disks in the server case.  Five are in the array, two are just sitting there powered on and spun down.

 

The problem:  I can't remember if I precleared them.  Is there any simple way to tell? When I look at them in unmenu the 2 disks in question have 1 partition on them (sdd and sdd1; and sde and sde1) with 2TB of space (2000.3G to be more accurate)

./preclear_disk.sh -t /dev/sdX

 

I just had to do the same for a drive that I'd swapped between servers.

Thanks for the reply watskooo, Answers breed questions.

 

The command you recommended, at what position in the directory structure is that to be executed - root?

 

Is there a comprehensive preclear document that shows the options/commands?

IIRC, it is at the root level..

 

cd /boot

 

preclear_disk.sh -?

will give you a list of commands and help info.

If you execute it as

./preclear_disk.sh

then it must reside in the current directory.

 

Typically, most people download it to their flash drive, so you would first have to change directory to /boot

and then invoke the command.

cd /boot

preclear_disk.sh -?
