My disk 6 is disabled and being emulated.  Array Devices screen says 2048 errors.

 

disk log shows this a few times :

 

Oct 17 16:41:14 Tower kernel: critical target error, dev sdd, sector 15628052928 op 0x0:(READ) flags 0x80700 phys_seg 1 prio class 2

Oct 17 16:41:14 Tower kernel: Buffer I/O error on dev sdd1, logical block 15628052865, async page read

 

I was running three sync processes to compare files on it at the time, plug copying down one large file and up one large file.

 

This morning, I moved the HBA card from one PCI to another PCI location also.

 

I have a hot spare disk that I can move into place - but it is a 10TB and the disk with the issue is an 8TB - my last 8TB.

 

The dashboard says healthy against this disk and a tick - which seems to contradict the errors shown in the array devices screen.

 

Is it possible this relates to the HBA move ?

 

Should I just do a reboot - will it come back - or should I bite the bullet and put the hot swap in there.

 

Timing is terrible as I bought a new 10TB yesterday that has read errors during the pre-clear, tried it in another unraid server and the same thing soon as it is attached so not likely a sata cable issue.  Will take time to get a repacement and I hate not having one ready to go.

Disk dropped offline so there's no SMART, check/replace cables and post new diags after array start.

I stopped the array, shutdown.

Swapped the sata cable with one from the mobo rather than the hba.

Started back up.

Disk has an X next to it again, and all says contents emulated.

New diags attached.

added disk log.

I bit the bullet and pulled this disk and am now rebuilding on the hot spare.

Fingeres crossed in 1 day and 9 hours (it says)

Well balls.

My hot spare is now also showing read errors during the parity rebuild and it has stopped building........

Unraid is certainly keeping me alive and kicking today....

So the 10TB hot spare had errors also (it was a preclear only on the weekend and was all fine then).

My IT shop only had 8TB's in stock, so I had to get that.  No time to pre-clear as running with no parity.

Connected that up - and as its smaller than the 10TB hot spare I tried - it could not be added.  Oh!

So - tools/new config and rebuilding parity again.  13 hours it says - I would say fingeres crossed, but that did not help last time.......

 

so you are building parity again... and wiping away the failed disk... sorry that's happening... by chance what WATTs is your PSU?

 

A long time ago I had issue in a build and it wasnt till I went OVERKILL on one PSU 1200 watts for 10 hdds... that I didnt encounter issues again... Im about to use that PSU again on a new build(psu 10 years old now) hoping all works well... we will see

Its an 800W, there ae 7 drives and if anything it has less power use now, as I removed an SSD file cache drive that I merges onto the main cache drive (and later will be replaced with an NVME. 

Old disk looks healthy, so most likely a power/connection issue, did you also swap/replaced the power cable?

yep, I moved it to a higher a lot so different cables

new disk in the same place it has always been now.

 

Post new diags.

It’s still rebuilding parity from the new config.  Will do tomorrow.

Rebuild of parity is complete - 0 errors.

Uploading diags now.

If what you say is ture, and that removed 8TB drive is acually ok, then it will go into my backup unraid server with all the other replaced drives over time.

I will add it in and pre-clear it for a check.

Everything looks good for now.

Sounds good.
