Adapting Core drive to Scale

[adamuso]

In my infinite wisdom, before migrating core to scale with the Web UI update on Core 13 stable, I have pulled one of the disks.
The upgrade went very smooth. However the disk that has not been in the system is now treated as an unknown disk and not part of the data pool.

Is there a way to adapt it to scale and add it back to the pool without having to rebuild it ?

I run just 2 disks in raidz1, therefore the pool can be reconstructed, however if it is possible to import it that would be the preffered option.

If this is common knowlege, please excuse me, I did not find it. (Search engines suck these days)

You will need to replace and resilver.

The word "raidz1" means single parity striping, somewhat like RAID-5. But, it has a minimum of 3 disks. I guess it is possible you forced it to make a 2 disk RAID-Z1.

But, it is more likely you meant Mirror, which is somewhat like RAID-1.

Using the right terminology helps avoid guess work.
