Hey guys,
So I have this kinda old Truenas box that I've been keeping up to date software wise but from a hardware perspective, it's pretty much at end of life. I have 2 pools, a mirror of 2 SSDs, this one is fine but the other one, the main one, has disk that have over 11 years of power on hours (and 2 of them have VERY noisy bearings). It's setup as a stripe of 3 mirrors, each with 2 disks. All WDC RED (CMR)
Looking at my options, I could definitely just swap them all 1 by 1 with newer disks - buying 6 disks... but looking at the prices of HDDs, I could simply remove the 6 disks and replace with a single mirror of way higher capacity drives, like WD Red Plus 14TB and it's almost 50% cheaper & consumes less energy. It *might* be slower (would need to check benchmarks) but I'm using this as a destination for backups and running 1gbit networking right now which is definitely slower than a WD Red Plus.
Now here's the thing : my motherboard + SAS cards are maxed out. Can't add any new drive in to just replicate everything so I'm unsure how I could, like, backup everything, destroy the pool and recreate with the new drives.
Also problematic is I have all of my apps + 2 small VMs sitting on this pool.
Thought of a few options, unsure what could work :
1-Remove one of the 3tb drive, run in degraded mode on this pool... plug 1 of the new disk in, replicate everything... rip out the leftovers from the original pool, put the 2nd new disk in and extend the pool to it... (or remove 2 disks from the first pool...)
2-Use a USB to Sata enclosure to connect 1 of the new drive directly to the Truenas box, replicate and then kill the original pool, put the new drives in and run with it?
3-Seems convoluted but I feel like I could possibly do this without having to migrate / reconfigure anything :
-Setup Trunas Scale in a VM on my desktop, creating the ZPool on the 2 new disks (connected over SATA or with the USB adapter)
-Replicate everything to this new Truenas scale instance
-once done, rip the 6 disk ZPool out and install the 2 disk pool in... as a replacement for the existing one... <-- Is that even possible? Keeping shares, snapshots, apps, etc
Anyway, open to suggestions... My other idea was that the hardware is really old and I could just build a new box entirely with the new disks :P Finding a case for 2 disks is way easier than 6 with hotswap... and I won't need the SAS controller, etc etc.
