Hello!
I currently have a pool consisting of one vdev with 3x3tb in RAIDZ1. I am pretty sure that atleast one of the drives is very close to dying, while it seems like a second drive is also struggling. I get errors like:
And S.M.A.R.T for ada0 is saying:
And for ada1 it's saying:
And lastly ada2 which seems fine:
So am I correct in reading that this is not promising for my pool? Either way I'm overdue to increase my storage with larger drives.
My plan is to retire all three of these drives and replace them with a brand spanking new vdev of 3x18tb still in RAIDZ1. Only problem is my old (and not suitable for server-usage) motherboard ASRock J4205-ITX only has 4 sata ports. The motherboard also suffers from a horrible Realtek RTL8111GR network controller and only one PCI Express 2.0 x1 Slot (500MB/s).
So I need a solution to get data from my old vdev over to my new vdev. There are several I can think of, and I'll list them now:
New motherboard with 6+ sata ports (420 - 646 eur plus ram ~150eur)
This is by far the most tempting and expensive solution. The candidates here are:
Supermicro A2SDi-4C-HLN4F - somewhat affordable at 3999nok (420eur), but the CPU seems to perform the same as my current one, around 2000 on the cpubenchmark.net
Supermicro A2SDi-8C-HLN4F - 6147nok (646eur), 50% more expensive, 100% better result at cpubenchmark.net. But this one might need active cooling while the other might get away with passive cooling.
Added benefit with these boards that I also get a proper network card, Intel C3000. As well as KVM on dedicated LAN and IPMI2.0. Although I would need new RAM which adds to the cost (I'm really overdue for a RAM upgrade though, with the 2x4GB I have today, soo benefit..?)
Extra drive (170 - 270 eur)
Just realized that I can also buy a 8TB drive and move everything there temporarily, then set up my new pool, and lastly transfer the data. Could invest in a proper nas drive to have it for snapshots and backups. Or just a really cheap and small drive.
HBA Card (50 - 100 eur)
Cheap solution. Get a second hand LSI-card and use it temporarly while transfering the data. This will probably be slow though, given that it would sit in a x1 slot. Will it even fit?
Ghetto (0 eur)
I could probably do a real ghetto solution of removing one drive, transfer data and then resilver.
So in the end I guess my question is, which solution would you go for? Is there anything I have missed? Do you see any clear downsides to these solutions that maybe sways the decision in any direction?
Sorry for the long winded post! Any input is appreciated :)
