Hello guys,
My Freenas system (9.10 U6) have a ZPOOL composed by TWO VDEV of 6 DISKS each in RAID Z2
Thanks to the case SC-4324S and the HBA 9305-24i I still have 12 slots free to add disks.
Now, in my first VDEV (composed by the 6 x 3TB) there is a disk that it's going to die so I would like to replace all 3TB disks with 8TB disks (already purchased 6 X ST8000NM000A).
I saw that basically I have the choice of replacing each 3TB old disk with 8TB new disk and have my VDEV in degraded mode OR put my 6 new 8TB disks in other slots and replace the 3TB disks but during the resilver the pool will not be degraded because the 3TB disks will remain all connected until the end.
I saw also some people talking about CLI and strange commands and UID and serial numbers and other stuff but I didn't went too much into it.
Can somebody explain to me (step by step if it's possible) the best and safe way to replace my 6 x 3TB disks with 6 x 8TB disks from the GUI either replacing them one by one or connect all the 8TB disks on the free SATA slots and then migrate/resilver ?
I also add three screenshots of my ZPOOL situation to avoid misunderstanding in case I did some mistake in explaining how my VDEVs are configured.
