So currently have an older Truenas core v13 build. Its been working perfectly over the past 4 years or so but now several of the disks are showing Smart errors. So I think its time to do some housekeeping.
First, I already backed up everything to a local 12TB USB backup drive!
5 of the 6 SSD’s have errors, I am planning to get those ready to RMA back to Samsung (hope this works and goes well, LOL).
I then plan to rebuild but this time with a few improvements!
Previous system:
1 large vdev RAID Z1 with the 6 2TB SSD’s ~10TB of space
1GB Networking
The new system I am thinking would be:
Since my MB supports up to 8 Sata connections, I will add 2 more 2TB SSD’s.
Striped RAID-Z1 (2 vdevs x 4 drives), total capacity ~12TB
Then since my MB has 2 local M.2 slots, I will have a mirrored svdev for metadata
Then to top this off, I will upgrade from my existing 1G home network, to 10G back to the NAS.
There could theoretically be some scenarios where an NVMe (if those M.2 slots are NVMe - I would think so but it’s not guaranteed) SSD special vdev could further increase the performance of a SATA SSD pool but I can’t think of a homelab (or other) scenario where that would be noticeable without a full NVMe pool being needed.
Interesting, yea I read about the special Vdev but was not aware it may not be needed if using SSD’s as the primary storage pool. I am fine without spending time/money on that part if its not really going to greatly improve the performance.
Sorry for answering that late but yeah the overall plans sounds good I think. As you haven’t mentioned any specific hardware it’s a bit hard to say though.
