My actual setup is a Qnap TS253 with 2x14 TB Ironwolf Pro.
The system is completly encryted and is “enabled” with injecting an external ssh command to encrypt after a new startup. This is working since a long time.
I bought an UGREEN DXP2800 with 32 GB Ram (and installed truenas on the 1st NVME there) and want to move the data to it w/o having to purchase an extra Ironwolf HDD.
So the first question is: is this kind of complete encryption possible with truenas ?
and now how is the bestways to proceed with “migration” ? My thought is (i have a 2TB hdd available)
create a volume on this 2 TB HDD and create the same directory structure like on the TS253 (i use the nas only for sharing files via NFS/SMB)
insert one of the 14 TB HDDs to have mirroring (RAID1)
remove 2 TB HDD
resize remaining 14 TB HDD to complete size
transfer all data from TS253
insert 2nd HDD from TS253 and let Truenas mirror on this HDD
sell TS253
Any hints ?
ATM im struggeling setting up a volume with a single disk…
The two drives are Mirrored on the Qnap? If those are the only drives you have and you are willing to take the risk of a single drive in Qnap and TrueNAS while copying data, etc., I would just remove one 14TB from the Qnap. You get a degraded Mirror.
Put 14TB in TrueNAS and create the pool. Single stripe VDEV. Copy your data from Qnap to TrueNAS.
Once confirmed data is there, remove other drive from Qnap and you add it to your VDEV as a Mirror. Verify you are getting a Mirror and not adding a second, single stripe VDEV.
As for Encryption. You will need to go over the TrueNAS documentation for the version you wish to use and see if that is what you intend. You have choices such as the Dataset layout. I think the suggestion is creating a Parent dataset (unencrypted) and then a Child dataset (encrypted)
There are two choices, key and passphrase. I think you are interested in passphrase from how you describe Qnap. Research what is and isn’t encrypted on a TrueNAS setup.
I think i can take the risk for those HDDs because important data there, i have elsewhre and the rest are only videos which i can get again (ok it will take time to download but i can get it)
