Hi,
I'm curently planning to move my CentOS/mdadm/RAID5 data to a FreeNAS ZFS. I'm new in ZFS. Here is my plan and my setup.
- I have curently 3x3Tb RAID 5 on mdadm.
- I was able to move half of data on temporary storage; but 2.7 Tb remaining. I just bought a new 3Tb drive.
My initial plan was to copy the 2.7Tb to my new drive, clean my RAID5 and built the new setup in a ZFS.
After copying all data on the ZFS, include my new/temporary drive to the ZFS, as we can do in RAID5.
But, as I was reading, it's not possible ? Can you confirm ?As I can understand, to increase the space of ZFS, I must create a new VDEV with my new drive. But this new VDEV, with only one drive, will not be redundant.
Am I understood corectly ? Any way to add a fourth drive to my system ?
Thnaks for your help,
