Pro 6 disk replacement yields unexpected size
Hi!
I have an old Pro 6 with current firmware and a single FlexRaid 2 volume.
I have replaced a 1TB drive with a 3TB drive in order to get a bit more space.
I went from:
3 x 1 TB
2 x 1.5 TB
1 x 2 TB
to
2 x 1 TB
2 x 1.5 TB
1 x 2 TB
1 x 3 TB
Expansion took place without errors. IIRC it expanded from 5.5TB to 6.0TB which I don't understand, I would have expected 6TB to 7TB. I seem to misunderstand the way FlexRaid 2 works.
I would be grateful if somebody could enlighten me.
Thanks a lot in advance,
Gunnar

- You should back up at least the critical data if two disks are at risk.
If disk 1 had a read error when you replace disk 2, you will lose all your data - the raid sync will fail, and the volume will be dead.
So back up what you can before you replace disk 2. - It seems this is the correct size for this constellation.
Have ordered two new disks (sigh) and will replace the faulty ones when they arrive.
Thanks to everybody for the great support.
