Two New 8TB Drive for Our NAS

Our NAS has run out of space again. I saw a deal that the Seagate IronWolf 8TB NAS Hard Drive was on sale at newegg for $309 CAD. I jumped at the chance and purchased two.

I am now following the same step as I outlined in this post. Replacing two old 4TB drives with these two new 8TB drives.

So far so good. Hopefully when all is said and done, my NAS will have a total of 18TB in a RAID 1 configuration of 6 hard drives in total. Two 4TB, two 6TB, and the two new 8TB.

I noticed that I could fit two more drives in my chassis and may decide to re-add the two old 4 TB back in, but first I’ll have to check if my power supply can handle the demand.

I really like this mdadm and LVM setup.

Update: After 2 mdadm syncs, each of which was around 8 hours, and a pvresize that also took another 5 hours. I had to convert the filesystem from 32 bits to 64 bits using these very helpful instructions. Only after I converted to 64 bits can I then expand the existing filesystem to more than 16TB. It was a learning and yet rewarding experience. Next step is to reuse the 2 old 4TB drives in the same chassis and add them to the logical volume.
