I am thinking of moving from a Synology DS1520+ NAS to TrueNAS Core running on a PC build. The Synology has 7x12TB drives in a RAID 6 configuration for a usable capacity of 52.4TB, of which I am using about 20.5TB. I was hoping to keep the cost of the planned build down.
My question is: Can I start off creating a Storage Pool in a "stripe" layout with (2) 12TB drives and then once I migrate the data from the Synology to the TrueNAS, wipe the existing drives... add them to the TrueNAS pool and convert from a "stripe" layout to a "RAIDZ2" layout without losing the data, or do I need to start off with (3) drives using a "RAIDZ1" layout and then expand/convert to "RAID Z2". Thanks in advance.
