June 30, 201511 yr I have a data drive that has been reporting errors for a while so I decided to replace it. I used the instructions at http://lime-technology.com/wiki/index.php?title=Replacing_a_Data_Drive The drive I replaced the old drive with is an identical drive (same batch from several years ago). Fresh out of the sealed static bag. When I go into unraid after the reboot, Unraid reports the parity is missing. Now maybe I pulled the parity drive? I figured out my drive slot by going to the mount point and doing an ls -Rl and watching for disk activity. I didn't see any other active drives when I did this and I assumed a ls -Rl wouldn't affect the parity drive. The pull-down for the parity drive reports two drives that aren't the same as the one that is missing. So, I did replace the wrong drive... correct? What did I do wrong?
June 30, 201511 yr Check the serial numbers. The webGUI will show you for each slot the expected drive with serial number when the array is stopped (see Main -> Array Devices). Check this with the one you pulled out.
June 30, 201511 yr Author Thanks. I confirmed that I pulled the wrong disk. Unraid is awesome. I'm saddened that I have to start replacing drives soon since it's only a matter of time before they all start to go. That said, I think I got the right drive now and it says I have two drives to choose from. My setup has been running pretty much by itself since 2009, so I barely remember what I did. I guess I might have an extra drive in there that I never configured... Mark
June 30, 201511 yr With unRAID v6 you can create SMART reports for each of your drives and post them on the forum. There are several experts here who can give you advice based on those reports.
