Disk replacement woes

[Big Mike]

I have an array of 12 2TB disks. I bought two replacement 4TB disks to expand the array, from E-Bay. Both new disks were cleared with the preclear app. I upgraded the parity disk without problems, the parity was fully rebuilt. I then replaced one of the data disks but the disk reported write errors and this new 4TB data disk was disabled. I then tried to replace this disk with the original 2TB disk but the array won't start because it says the disk must be 2TB or larger.

 

Is there any way I can put the 2TB disk back in and rebuild the array with the 2TB disk while I investigate the 4TB disk?

 

Thanks

You can do a new config.

New config?

Tools -> New config

 

Keep all assignments, then re-assign old data disk and start array to begin parity sync.

See here, in the manual: https://wiki.unraid.net/Manual/Storage_Management#Reset_the_array_configuration

Cool, I'll take a look.
