I have a few vdevs all of 2 drives in mirror. So 1+1, 1+1, 1+1, 1+1.
They are currently all 4TB 4k SAS3 Drives. I've ran out of storage space and physical room for new drives, and don't have the funds to grab a new chassis at the moment.
What I was planning on doing is ordering 2x 8TB 4k SAS drives to use.
My question is, is it 100% safe to turn off, remove drive 1 in vdev 1, turn it back on, let it resilver, then turn it back off, and remove drive 2 in vdev 1, turn back on and let it resilver from the new drive 1.
I should then havs 3 vdevs of 4tb drives, then 1vdev of 8tb drives, and have more storage space available on that pool correct?
Furthermore, there is no real way my pool can be screwed up correct? Because I can always pop in the old drives and all my data is back.
And are there any other considerations?
