Hi!
I've searched for this and would just like to verify the answer that I think I have found. I currently have 2 3TB VDEVs that are striped providing a pool 6TB is size. Each VDEV consists of 2 3TB drives that are mirrored. I would like to replace 1 VDEV with 2 4TB drives that are mirrored so I end up with 7TB total.
What I have read is that I replace 1 3TB drive in a VDEV with a 4TB drive. Let the resilver process complete. Then I can replace the 2nd 3TB drive in the VDEV with a 4TB drive and when it resilvers, the VDEV will automatically increase to 4TB and I will have my 7TB total capacity?
Question 1: is the above true?
Question 2: In order to retain 2 drive redundancy, can I add a 4TB to 1 VDEV making it a 3 disk mirrored set? Once I do that, can I then replace a 3TB drive with a 4TB drive. Once that is resilvered, can I then remove the final 3TB drive?
Thank you for your help!
Very respectfully,
John
