hi, is this still a valid procedure to decommission a drive ?

 

https://docs.unraid.net/legacy/FAQ/shrink-array/#the-clear-drive-then-remove-drive-method

 

haven't found anything non-legacy to shrink an array

 

my drive is empty (cleared it out with unbalanced ), just want to confirm if these steps still hold

I'm planning to remove a 6tb and replace it with a 12tb. I'd like to shrink before adding/replacing. I'm not helping at all, but I'm most interested in the answer.

It is, but don't use the script, as it's not working correctly with current versions, you can still do it manually, if you prefer that option

You would typically just rebuild on the new drive, not shrink then grow again.

ran it overnight, went withouth a hitch. thanks again for the procedure !

question, it did leave a "hole" in the disk sequence, i can live with it, but ... is there a way to close the gap ?

 

maybe reassigning all disks, then calculate a new parity ?

 

i will probably remove another disk first though

 

any thoughts ?

How many parity disks do you have?

only one

If you only have parity1 then it can be done quickly as the drive slot is not part of the parity calculation (whereas it IS for parity2).   On that basis you can:

• Use the New Config tool and select the option to retain all current assignments
• Return to the Main tab and reorder the array drives to the order you want
• Check the Parity is Valid checkbox.    This will stop Unraid rebuilding parity (despite the warning which ignores this checkbox)
• Start the array to commit the new assignments
• If you have any User shares that have entries for the Included (or excluded) drives change them to match the new drive assignments.

thanks a lot itimpi !

 

it just worked 👍

question, i cleared another drive, only i just copied data, didn't move it. 

 

can i start with dd right away, or should i format it/delete file first ?

As long as the data is not important you can use dd right away.
