Error message when replacing device.

[lotustechie]

I keep getting device too small error messages when trying to replace disks. The disks are exactly the same size and this time it is literally the same physical drive, I just wiped it. I was able to get it to work via CLI, but I would like to do it the right way. Anyone have any ideas?

Yikes. Can you post what disks they are?

You might have a chance to squeeze out a couple GB by temporarily disabling swap partition creation (on new drives), by setting the following option to 0 GB:

System -> Advanced -> Storage -> Swap Size

Then try to add the new drive again?

I hope you have a proper, recent backup of everything.

(The above trick assumes you kept the default setting of 2 GB when you created your initial vdevs/pool.)
