Hello,I have a homelab with pfsense, proxmox, truenas, ubiquity, cisco, and synology. Currently, my truenas is shut down with 6x16 TB seagate exos drives. My synology is a DS1817+ with 8x10 TB Seagate Ironwolf drives in SHR-2. The Synology is currently 77% full with 40.2 TB stored (total capacity of 54.5 TB).

In an effort to save on the electric bill, I am decommissioning the truenas. I also have a 12 tb seagate Ironwolf drive as a cold spare.

I’m thinking of doing the following:

Swap 7 of the 8 drives in my Synology from the 10 tb capacity, to the 12 or 16 tb capacity.

However this would be a resilver of a total of 7 times plus one more to expand.

That being said, I would like to know if this is something I should do.

SMART on all drives is good. One of the 10 tb drives has 8 bad sectors, but is otherwise healthy.

Also with SHR-2, I need to replace a minimum of 4 drives to see any increase in storage.

The truenas was the biggest culprit in the electric bill running two intel Xeon e5-2650 v3 processors and 320 gb ecc ram.

The second biggest energy hogs were the proxmox boxes running on a pair of lenovo thinkstation c30’s each with two intel xeon e5-2620 v2’s in them and 64 gb of ecc ram in each.

The question I have is should I increase my storage on the synology, and if so, should I offload the data and swap all drives at once? Or should I keep the data in one place as I resilver the drives 7-8 times?

I have a friend who might be willing to host my data temporarily, however, his availability is limited to 12x 3tb drives, which means, even if he runs RAID 5, that I have roughly 10 TB too much data for that, and will need to delete some.

Currently my budget is $0 and to use what I have first.

What would you do?
