HDDs keep failing - unlucky or some other issue

[kilo]

My Unraid Server has been running for 18 months now, and it's built with a 3-disk array (1x parity, 2x data).

Within this time, 3 disks have failed:

- the parity disk

- a data disk

- a replacement data disk that replaced the first failed disk

 

Only 1 disk in the array is an original one.

 

Is this typical? Am I just unlucky. Or is something with the running, or the environment that could be impacting disk lifespan?

Without diags it's difficult to say more, are you sure the the disks really failed? Power/connection problems are much more common.

2 have been accepted and RMAd successfully. The third is on its way back now.

 

With this one, I got an alert: Disk 1 in error state (disk dsbl)

 

Looked at the log and got a bunch or read & write errors like:
 

Dec 9 18:27:40 unraid kernel: blk_update_request: I/O error, dev sde, sector 6458159280 op 0x0:(READ) flags 0x0 phys_seg 12 prio class 0
Dec 9 18:27:40 unraid kernel: md: disk1 read error, sector=6458159216

 

Powered off / checked connections / powered on

Checked in the GUI, Disk 1 was now showing "Not installed"
So, RMAd and will see if the vendor accepts it okay 🤞

You should ateast check the SMART report and/or run an extended SMART test.

Yes. I did this but it would not run. I’ve got the log somewhere but it just had a couple of lines in. Nothing useful I think

If it happens again post the complete diagnostics.
