Hi,

 

I have an Acer H340 4-bay home server running unraid (2x2TB, 2x1TB) 5.0-rc5

 

This afternoon, I heard one of the drives kept spinning up and down and I went to the webGUI, it shows a red ball by the parity drive. I stopped unraid, unplugged the parity drive, plugged it back in, clicked "refresh", unraid could not find the parity drive (the drive selection drop down has nothing except "no drive").

 

I took out the parity drive, ran seaTools, could not find any issue. Tried other drives on where the parity drive bay was, unraid could not find the drive still.

 

I suspected there might be something wrong with the server hardware. So I took it apart, checked connectors, cleaned dust. Put it all back together - working again!

 

However, unraid recognized the old parity harddrive as a new parity drive, and it is now rebuilding parity. While it is building parity, one of the data drive is showing increasing number of "Error" counts. It is now 67% done with 378 Errors. 

 

Does that indicate potential data-loss of the data-drive? If I replace the faulty data drive with a new one, would it cause any other troubles?

 

Thanks!

It means parity is being created with errors. Copy the files off the faulty drive.

Thanks for the reply, but by "copy the files off the faulty drive" - what does it fix? Files that used to have errors will still have the same errors.

 

Also, I don't have spare 1T to move the files, but will replace the drive with a 2T in a few weeks.

My parity drive is offline again today for no reason. The web GUI says "no disk" even the drive is in the slot. Data drive also has the error reading.
