I'm looking to swap a 2TB for a 3TB drive in an unRAID array - so much so usual.

 

However I don't currently have a parity drive on the array (this is part of the master plan to implement one). Is it possible to simply clone the 2TB to a 3TB disk outside of unRAID (with the array down, of course), expand it, and then add back in in place of the old 2TB? Am I likely to see issues with config, lose data, etc.?

 

I've looked around but all references to this type of issue presuppose a valid parity disk, which I don't have.

Why not just add it to the array and move the data between the disks?

I can't add a new drive to the array because I can't buy the pro version yet, because I don't have a USB stick that it'll accept (and I have 2 data disks installed).

you could remove the old drive, add the new drive.

then mount the old drive not as part of the array, but as an extra disk (see my signature for an easy mount plugin).

then just copy the complete disk over to the new array disk.

How does that compare to cloning outside of unRAID ? Say with something like Partclone?

 

I guess in theory it should be equivalent?

i believe so...

i could be, that you would have to select new config, so unraid doesn't want to clear and format the drive. (not sure, what unraid does, when there is no parity drive present)

Just do as suggested. Put in the 3T drive and mount the 2T outside the array and copy the data over.

 

unMENU can mount and share the drive or use the mounting plugin.
