Hi all,

 

My regular data-parity check found 2044 errors (how do I fond what kinds) and marked the disk as disabled and content emulated.

I have removed the disk from the array and run the preclear process without any issues with spot on speed.

However, after adding the disk back to the array and starting the data-rebuild process the disk has issues.

At the beginning everything was fine but then the disk started making low, short and vibrating noise in regular intervals and the speed dropped to 0.

 

Any ideas?

 

The logs show something like this:

spelling :/

Next time please post the complete diags but based on that looks more like a power/connection problem, replace/swap both cables/slot and try again, if the problem follows the disk it's likely a disk problem.

OK, will do next time.

 

(Simplifying the journey and removing all the swearing).

I changed a cable and the disk died (it was a funny looking old cable).

I changed the cable again but the disk was dead.

I changed a disk and everything works fine.

 

 

The dead disk was successfully recovered afterwards, I think.

I will test it properly (preclear) later.

Also, the original cable was part of 4-split HBA cable and that particular one was flaky first few times I attached it. A disk connected with it was not working. Lesson learned, if something works funny even for a short period of time just don't trust it.
