Shrink array, some questions before I start the process

Recommended Posts

So this is the case.


I want to remove 2 drives from my array and replace my parity drive with a larger one.


The 2 drives I want to remove from my array are completely empty. So I thought I should use the script to zero out my drives.

I created the clear-me folder. on disk1. But now I also got a share that is called clear-me that has cache:preferer. This also means that I got a clear-me folder on cache drive. So I assume that somewhere I did something wrong in the process 


So I was wondering if it would be better to all this in one process. disk 1 and 2 are completely empty. So can I just remove those drives and replace parity in one operation since parity have to rebuild anyway if I use the  "Remove Drives Then Rebuild Parity Method"?


Something like this:


New config - Retain current configuration - all

Unassign disk1 and disk2

Replace parity with the new parity drive

Start array and let parity rebuild on new parity drive

Assuming contents of 3x3TB will fit on 8TB:

  1. Replace fullest of the 3TB with the 8TB and rebuild.
  2. Copy the other 2x3TB to that 8TB.
  3. New Config without those 2x3TB, rebuild parity.

Also assuming there is nothing wrong with any of your disks. If you are having disk problems, or if you just want us to take a look:
