Hi All,
I'm sure this question has been answered previously but I'll admit I wasn't sure what to search.
I currently have a ZFS pool with 2 data VDEVs or mirrors.
VDEV 1 has 2 6TB disks in RAID1
VDEV 2 has 2 2TB disks in RAID1.
zpool status:
The pool is then of course striped across the two VDEVs.
I'm now running out of capacity so I've ordered 2 new 6TB disks which are the same as the two I currently have to replace the two 2TB disks (they're old and my chassis only has room for 4 disks).
I understand I can replace one of the 2TB disks, resilver, then add the next 6TB and resilver again, but that will only leave me with 12TB of usuable storage.
What I want to do is "rebuild" the pool so that I can have RAIDZ parity across the four 6TB disks.
How do I "re-arrange" the zpool?
Any help appreciated! Thanks!
