How to Migrate Your QNAP NAS from Single Disk No RAID to RAID 1, 5 & 6

RAID 1:
Understanding RAID 1: Redundancy for Data Security
Description:
RAID 1, also known as mirroring, is a data storage technique that duplicates data across multiple drives to ensure redundancy and fault tolerance. In this video, we delve into the fundamentals of RAID 1, exploring how it works, its benefits, and its applications. Whether you're a beginner looking to understand RAID configurations or an IT professional seeking to bolster data security, this video provides valuable insights into the world of RAID 1.
RAID 5:
Exploring RAID 5: Balancing Performance and Redundancy
Description:
RAID 5 is a popular choice for balancing performance and redundancy in data storage systems. By distributing parity data across multiple drives, RAID 5 offers fault tolerance while optimizing storage capacity and read/write performance. Join us in this video as we unravel the intricacies of RAID 5, discussing its advantages, implementation considerations, and best practices. Whether you're building a NAS, server, or enterprise storage solution, understanding RAID 5 is essential for maximizing data integrity and performance.
RAID 6:
Unravelling RAID 6: Enhanced Fault Tolerance for Critical Data
Description:
When it comes to protecting critical data against multiple drive failures, RAID 6 emerges as a robust solution. With its dual parity scheme, RAID 6 offers increased fault tolerance and data reliability, making it ideal for mission-critical applications. In this comprehensive guide, we explore the mechanics of RAID 6, its performance implications, and deployment considerations. Whether you're managing an enterprise storage infrastructure or safeguarding valuable assets at home, understanding RAID 6 is crucial for ensuring data integrity and continuity. Join us as we delve into the world of RAID 6 and unlock its full potential for your storage needs.

I presume I could take the two discs as a RAID 1 out of my TS-262. And install them into a TS-462, add a third disc and it will allow me to migrate to RAID 5.

[@QNAPUK]

Yes absolutely!

[@egg399.]

Can you do this on hero?

[@henrikrude8685]

Hi. Thank you for the guide.
I have a TS-262 I have started with a 2Tb SSD-drive and thin volumes. I have made a storage pool with 7 volumes.
I want to mirror my drive (Raid1), so I have installed a 2Tb HDD-drive (Storage Pool 2) with 1. thin volume.
When I come to the part (1:46 / 7:51) where I should "Manage" my Storage Pool, The "Manage" button is grey and not available? So I don't get the option to "Migrate Raid Group". Do you have ideas to how I can get further?

[@QNAPUK]

To migrate the RAID group you need to have a free drive... it sounds like the second drive you installed is already being used for Storage Pool 2 so it cannot be used.
Ideally the drives in a RAID1 would be the same type of drive too, as drive1 is SSD it would be recommended to have drive2 as an SSD as well.

I havent checked my nas in a while but I think Im running Raid5(four disks, one as spare). Im only using about half of the available space, Im also the only user. My nas is mostly in sleepmode because Im a little afraid of having diskfailure due to three of the disks being ”older”. I havent had any diskfailures yet but a couple of years ago, during the pandemic actualy, one of the backplane connectors on my previous nas failed and I got a new nas as replacement since there wasnt any parts available :).
My question is: could/should I migrate from raid 5 to raid 6? I know Id probably have to copy everything and that would take a while but Ive done that before

[@QNAPUK]

We'd always recommend doing a backup when under taking any big change like this, but yes migrating to RAID 6 will provide you with more protection (2 drives failing) than RAID 5.

[@Pickupstix24]

under the manage tab i only have Recover RAID Group as an option on a RAID 0 drive.

[@QNAPUK]

Which NAS do you have and how many drives are in it? To go up to a RAID1 setup you will normally need an even number of drives for it to be possible.

“Hello, I have been adding disks to new simple RAID groups (I now have 3 simple RAID groups with one disk each). When adding the fourth disk, I wanted to create a RAID 5, but I think I can’t do it now. Is that correct? Is there any solution without data loss?”

[@QNAPUK]

Unfortunately no way to do it without removing the data off the disks first. You need to have a "free" disk, with no data/pools/volumes on it to be able to use it for migrating and expanding.

[@billyblack2979]

Why dont I have that second drop down box to create the raid 1?

[@coleblair9648]

Make sure you're selecting the pool, not the volume.

[@travelertrini]

How can I migrate from RAID 0 to RAID 5?

[@QNAPUK]

Unfortunately not possible, we support RAID migration from Single drive to RAID1, RAID1 to RAID5 and then finally RAID5 to RAID6.
