failure adding new HD'D

[codo1234]

hello, aim trying adding new HD of 2TARA.

its say :If this is a new array, move the largest disk into the parity slot.

If you are adding a new disk or replacing a disabled disk, try Parity-Swap.

 

the parity HD is also  2 TARA

For some reason unRAID thinks that the parity is smaller than the new disk.  Posting a screen shot of the main tab should allow us to see if this is the case.

 

What motherboard do you have?  It is possible that a small area on the parity disk has been reserved for what is known as a HPA.  Gigabyte motherboards seem to be particularly prone to doing this.

the MB is super micro X7SPA-HF

Go to Tools - Diagnostics and post the complete diagnostics zip. We can get the disk sizes from the SMART reports.

Current Parity:

Model Family:     SAMSUNG SpinPoint F4 EG (AF)
Device Model:     SAMSUNG HD204UI
Serial Number:    S2HFJ1BZ902507
LU WWN Device Id: 5 0024e9 00400f751
Firmware Version: 1AQ10001
User Capacity:    2,000,397,852,160 bytes [2.00 TB]

New Drive:

Model Family:     Seagate Barracuda LP
Device Model:     ST32000542AS
Serial Number:    5XW2WJY2
LU WWN Device Id: 5 000c50 03d1905a0
Firmware Version: CC38
User Capacity:    2,000,398,934,016 bytes [2.00 TB]

What's puzzling is disk1 is also smaller than the new drive, and the same size as parity:

Model Family:     Hitachi Deskstar 7K2000
Device Model:     Hitachi HDS722020ALA330
Serial Number:    JK1101YAG54KDV
LU WWN Device Id: 5 000cca 221c256fa
Firmware Version: JKAOA20N
User Capacity:    2,000,397,852,160 bytes [2.00 TB]

I don't have any 2TB installed currently. Anybody else know what the normal size of 2TB is?

 

Were parity and disk1 ever used with another motherboard?

 

 

If I understand you correctly, you are trying to add a new drive, not rebuild a drive, correct? If so, the quickest and simplest thing to do would be:

 

New Config without a parity drive and with the current parity drive as the new data drive.

 

Select a filesystem for the new data (old parity) drive, or let it use whatever you have for default (XFS if you haven't changed it under Disk Settings).

 

Start the array so the new config is saved and let it format the new data (old parity) drive.

 

Stop the array and assign the new bigger drive to the parity slot.

 

Start the array and let parity build to the new bigger drive.

 

 

If this isn't clear ask questions so you don't make any mistakes.

2TB disk should be:

 

2,000,398,934,016 bytes [2.00 TB]

trull - thanks

 

yes  i try to add the new 2TARA drive. not to change.

 

i think i did almost the same, i stopped the array, i changed between the HD'D of the 2TARA.

now its doing parity sync with the "big new 2TARA", and after it will finish i will add the "old" one to be disk4

 

correct?

You will have to preclear the old parity drive before you can add it after parity. If you had done it exactly like I said and built parity after adding the drive then you wouldn't have to preclear.
