I just bought a 2TB drive and want to add it to my array.  Since my current largest drive is 1TB (current parity drive), I need to make the new drive be parity and then just make the parity drive be another disk in the array (adding a 2TB drive gives me a net of 1 TB.  Not complaining, just laying everything out).

 

So, I'm nervous.  I have had my server for a year and it has been perfect.  I forget that I own it, which is what I wanted when I built it.  Now, I'm nervous about touching it.  I found this: http://lime-technology.com/wiki/index.php?title=Add_One_or_More_New_Data_Drives  but I want to make sure I'm not doing anything stupid before I start.  Anyone who cares to chime in with some steps or 'gotchas' would be greatly appreciated.

 

Thanks,

Chris

Start by doing a parity check with your existing parity drive in place.  You do not want to learn of an array problem when in the middle of the upgrade process.  If any errors occur, do not continue until they are resolved.

Do NOT re-assign the old parity drive as a new data drive just yet.  (We can always fall back to it if needed as a parity drive)

 

Once parity is calculated and written on the new drive press the "Check" button to read it back and confirm the new parity disk can be successfully read.

 

Once you have performed the parity check on the new parity drive you can then assign the old parity drive as a data drive.

 

Gotcha #1.  If you see any other drive as un-formatted, other than the one newly being added as a data drive where it is expected, do NOT press the "Format" button.
