Hi,

 

I'm having the following error in my array. One disk was disconnected at first and after a couple of reboots it shows connected with a red ball (Unraid2.jpg).

My idea is just to replace the drive with a new one and rebuild parity, can you guys confirm please? Thx!

You will have to rebuild the data disk, not rebuild parity. If you think it was just a bad connection you can rebuild back to the same disk. Post the SMART attributes of the drive. See v5 help in my sig

Thank you for the quick reply. Of course rebuilding the disk is what I meant.

It now shows 'not installed' again, so I guess replacing the disk is the way to go.

 

If you click on the dropdown does it show you the disk?

 

It might just be a bad connection. Without the SMART report for the drive I don't know whether to recommend using the disk or not.

 

Did you read the v5 help link in my sig? There is a lot of stuff there including how to get the SMART report.

 

When I click the dropdown the disk does not show.

So it looks impossible to get a smart report I guess.

 

Is it possible to change de physical connection of the disk (other SATA port) to check if it's the current connector and see if it's broken?

 

Or is it better to just replace the disk with a spare one and see how it goes? Bringing back the array healthy is my first priority. Thx

You can try power cycling the server and/or change sata port and check if the disk comes online, then do a SMART report.

If you already have a spare disk then there is a lot to be said for switching it in immediately to get your array back to a healthy state ASAP.    If you do this keep the old disk around untouched until the recovery finishes just in case anything goes wrong.  Once recovery has completed OK you can then safely start testing the old disk to see if it really has a problem or not.

Thank you for replying

 

I switched SATA ports and the drive is back with a red dot though.

Created a SMART report, what would you do?

smart.txt

SMART is ok, disk looks healthy, but healthy SMART does not always equal healthy drive, I would try a rebuild, if same disk fails again in the future replace it.

 

You can also do an extended SMART test before rebuilding, but it will take 5 or 6 hours.

 

Disk looks OK to me. Switching ports may have fixed it or maybe just replugging it was the fix. In any case it will have to be rebuilt before unRAID will use a disk assigned to that slot. Even though unRAID will not try to read or write from that disk slot until it is rebuilt, you should still be able to read from the emulated disk if you want to check your files.
