Duo v2 - Can't add second disc
Hi guys.
Can someone help? I'm trying to add a second disc to my x-raid volume. This is the second time I've tried. The first was with my original in slot 1. That failed, so I tried turning the NAS off and moving my original disk to slot 2 and putting the new disk in slot 1.
The existing volume is:
WDC WD20EARX-00PASB0 1863 GB (25 °C, Write-cache On). Status: OK
The new disk is a WD20EARX-00PASB0.
My NAS is a ReadyNAS Duo v2. Firmware RAIDiator 5.3.5. RAID type X-RAID2.
Once I have added the new disk, I get this within the logs:
Tue Jun 5 11:35:51 GMT 2012
New disk detected. If multiple disks have been added, they will be processed one at a time. Please do not remove any added disk(s) during this time. [Disk 1]
Tue Jun 5 11:35:59 GMT 2012
Data volume will be rebuilt with disk 1.
Tue Jun 5 11:36:17 GMT 2012
Disk removal detected. [Disk 1]
Tue Jun 5 11:36:17 GMT 2012
A disk was removed from the ReadyNAS. One or more RAID volumes are currently unprotected, and an additional disk failure or removal may result in data loss. Please add a replacement disk as soon as possible.
It seems to go fine until it says "Disk removal detected". I haven't removed the drive.. When watching the process in RAIDAR, it recognises the disk and then says the disk is DEAD before then saying the disk is not present. Wierd.
Can anyone help?

- Hi Migroo,
You can do XRAID with these hard drivers,
The disk has been qualified on Duo v2. evan wrote: smartctl can not open the disk, could you use WD tool (Western Digital Data LifeGuard Diagnostics - DLGDIAG for Windows
) in Whindows to write zeros? then do quick test using the tool, if it is OK, hot insert to Duo v2.
You had better not use WD Green disk do RAID, because WD officially doesn't support RAID user cases in more than 2-bay device for WD Green disk.***** Disk SMART log for channel 2 [sdb] *****
smartctl 5.42 2011-10-20 r3458 [armv5tel-linux-2.6.31.8.duov2] (local build)

Smartctl open device: /dev/sdb failed: No such device or address
Hi Evan
OK, sorry for the delay, but I finally did exactly what you wanted.
I used DLDIAG to write zeros (Quick Mode) and then did a quick test. Everything came back OK.
I then HOT inserted into bay 2.
I got the usual notifications in the info centre:
Tue Nov 27 21:38:20 GMT 2012
RAID sync finished on volume C. The array is still in degraded mode, however. This can be caused by a disk sync failure or failed disks in a multi-parity disk array.
Tue Nov 27 21:36:02 GMT 2012
RAID sync started on volume C.

Data volume will be rebuilt with disk 2.
Tue Nov 27 21:35:29 GMT 2012
New disk detected. If multiple disks have been added, they will be processed one at a time. Please do not remove any added disk(s) during this time. [Disk 2]
What is the next step?- Maybe the disk have been locked,
the below command can check the disk infomation,
hdparm -I /dev/sdb
Please contact support, they can remote access to check your system, thanks!
