Upgrading Disks 2tb to 4tb

Unread post by vimpircik » Fri May 18, 2018 12:32 pm

Hi everyone,

I have DS416play and 4 wd red 2tb disks with raid 5. It's nearly full and want to upgrade all disks to 4tb. How can I do this upgrade without loosing any data? Should I extract all data to external drives ( it takes so much time) or swap drives one by one? Does swapping disks one by one take much time?

What kind of way do I need to follow?

It is all neatly documented on the knowledge base of synology.

one by one swapping will take a lot of time (8-12 hours per drive), and the risk is, that another disk fails during the upgrade as creating the raid is a stressfull thing for drives, this may cost you all your data.

So a backup of all data to an external disk is advisable.
Please share if a reply was useful or how the issue was solved, it helps other DS users.

DS415+ (4TB HGST+ 4TB Seagate raid1 + 2*480GB SSD raid1), DS212+ (2*WD red 2TB), previous DS411J, DS106
