Hi,

 

New to unRAID and just doing some testing with 3 drives (1 parity, 2 data).

 

One of the drives shows a red X next to it. Not sure what the logs mean for it to be honest. I attached the smart and syslog files to this thread.

 

Any help to understand them would be appreciated.

 

Thanks

That drive is toast. Probably should not have been used at all. Did you preclear any of your drives?

 

Instead of syslog, always go to Tools - Diagnostics and post the complete diagnostics zip. It includes syslog, all SMART, and other useful things.

 

In fact, do it now so we can see what condition your other disks are in before recommending a course of action.

 

The red X means unRAID has disabled the disk due to a write error. It is being emulated now by reading all other drives plus parity to calculate the drives data. unRAID will not try to read or write a disabled disk. All reads and writes are to the emulated disk until the disabled disk is rebuilt.

Thanks for the quick response.

I attached the full Diagnostics this time.

As I mentioned, I'm just testing unRAID with some laying around hardware for a few weeks before I decide to pull the trigger on new hardware and buy a license. So the data on it is not critical at all and backed-up somewhere else already.

 

Can I replace the failed disk by a smaller size one (since there is almost no data on the array anyway)?

You can never rebuild to a smaller disk.

 

Parity disk doesn't look too good either.

 

Did you preclear any of these disks? You might as well do it even if just for a learning experience since you will need to test any new drives you buy before trusting them in your server.

No, I didn't preclear anything. I'll look into how to do this.

Thanks again.
