2TB to 4TB HDD Replacement: Data Degraded?

Hi,

I had 4 Harddisks in the ReayNAS-314: 4TB/4TB/2TB/2TB. Then I've exchanged the first 2TB Harddisk and waited for a complete resync. (Now 4TB/4TB/3TB/2TB)  After round about 24h syncing was completed. After that I've exchanged the last 2TB Harddisk. But now ReadNAS says "Degraded". What did I wrong? What can I do? How can I start a resync?

Greetings!
Ralf

    Can you send in your logs (see the sending logs link in my sig)?

    Is that a typo or did you really replace a 2TB disk with a 3TB disk?

      Hi,  I've sent the log. Yes it's no typo. ;-) I know, it's not so much difference, but I had two 3TB Harddisks unused.

        Actually there will be no space increase unless you do a factory reset.

         

        You can't add an intermediate size disk to an array.
