SATA-DOM drive died - now system says replacement SATA DOM is too small.

[KevDog]

I'm working with TrueNAS core 13.0 U2

I originally had bought two supermicro SATADOMs to mirror the boot drive. They were Supermicro SSD-DM064-PHI 64GB SATA DOM. One of boot drives died so I ended up reordering unit: https://www.newegg.com/supermicro-ssd-dm064-smcmvn1-other/p/1WK-0010-004Z1\.

FreeNAS lists the original SATA DOM as 59.63 GB, and the newly replaced drive as simply 59 GB:

Because of the "size" discrepancy, I can not attach the new drive to my boot pool, instead receiving the error:

It's the same device made by SuperMicro. Any suggestions or workaround here??

Thanks.

Export configuration, reinstall to both DOMs which will re-establish a mirror the size of the smaller drive, re-import configuration.

Seems easiest and fastest way to me, some downtime, of course. I cannot think of a way that completely avoids downtime.
