Back at the beginning of last year I built my new Unraid server.

I initially used the old drives I had (I was without a server for a little while).

They were the 3TB Seagate Barracudas. They were pretty old. It only took a few months for them to start giving me issues. The first one went, I just took it out and wrote all the data from it back to the array as I had space, same thing happened again to another drive, still had space so I took that out and rewrote it. Then gradually one by one they all giving me errors.

It got to August last year, and I just though I'll buy a bunch of new drives, so I went and bought 7 7TB Seagate Barracudas. I also threw the two good 3TBs in to the array.

All has been well until the past week or so.

I noticed about two weeks ago that the 3TB drives were giving me the orange triangle for smart status. Didn't think much of it, they are old and I am planning to replace them soon anyway.

Then last night I got in from work and noticed that one of the 4TB drives had dropped. I thought this surely can't be right, so I removed it from the array and added it again. At this point I noticed once I brought the array online that a different 4TB had gone 'missing'.

So I rebooted my server and then noticed a whole bunch of drives are just missing. Not discoverable at all.

The drives that I can see, are the parity, disk 1, disk 8, cache and another SSD I have added as an unnasigned device.

 

Now this motherboard has SAS x8 and Sata x4, and I'm pretty sure all but one of those drives are connected to Sata (not sure without opening the case which one is on SAS, I think it is Disk 1).

 

The motherboard I have is the Asrock E3C224D4I-14S which has 2 x mini SAS 8087 connector by LSI 2308.

 

I was a little suspicious before with all the old 3TB HDDs seemingly dying all within a 4-5 month period, they were all different ages, some bought in 2012, some bought in 2014. Been in 24 hour operation for a long a few years, but I was without a server for a year or so.

 

Any suggestions on where to go from here? Any help would be appreciated.

In fact, come to think of it.

The motherboard has 6 Sata.

I've not opened the case just yet, but it's possible that all the working drives are all on Sata and all the missing drives are on the SAS.

Diagnostics?
