Hello

 

I am going to be upgrading my parity drive and adding a larger cache pool drive.

 

I am keeping my current cache pool drive to use for app data, vms, etc and am wanting to use the new, larger cache pool drive for media transfers only.

 

I am adding a larger capacity parity drive and will be moving my current parity drive into the array as a data drive.

 

Is there a preferred order of operations that will result in limited down time/make it less impactful on me?

 

Thanks.

I assume you will be adding the other ‘cache’ drive as a new pool?   Assuming that is the case it is completely independent of the changes to the main array.

 

are you adding the old parity drive as a new data drive (or is it replacing an existing drive?

 

if it is going to replace an existing array data drive then the parity swap procedure should be used.
 

if it is going to be a new drive then you should first upgrade the parity drive:

- stop array

- unassign old parity drive

- assign replacement parity drive 

- start array to rebuild parity based on the current data drives..  keep the old parity drive intact while doing this, just in case any issues are encountered while building the new parity drive.

- when the parity build completes you can stop the array and assign the old parity drive to a new drive slot.

- start the array and Unraid will start Clearing the old parity drive. The array is usable while this is going on

- when the Clear completes the drive will shows as unmountable and you will have the option to format the drive to create an empty files system and make it ready for receiving files.

Yes, new pool for the new drive.

 

Old parity drive will become a new data drive, so I will follow the upgrade procedure you listed.

 

Much appreciated.
