Not Resyncing new drive - Volume not redundant - Drive dead

[ru55ell75]

Hi All,

For anyone out there with the issue of their NAS not rebuilding RAID volume redundancy after inserting a new drive and Frontview still reporting the old drive as dead,  I feel your pain!

 I didn't manage to find any aticle on here that helped but I found this article on how to force the resync process through ssh and it worked like a charm for me.

Hope it helps someone else

Hi Matt,

I experience the same problem with my Readynas Ultra 2. Inserted a new HDD in bay 2 but Frontview still showing the as dead. When I connect to the Nas through ssh and write the command: sgdisk -p /dev/sdc I receive the following output. The disk I see is the active i the X volume I suppose? Could you guide med how to proceed?

When I write the command df-h it says the volume is 4GB? Not showing in Qraidar!

zose the 4GB volume is the root volume. The data volume is the 914GB volume mounted at /c

sdc is your USB disk from looking at

# df -h

What do you see if you do e.g.

# cat /proc/mdstat

[zose]

Yes, mdgm you are absolutely correct about that. When I write the cat /proc/mdstat I get the output:

[mdgm-ntgr]

Do you see the disk you added if you do a

# cat /proc/partitions

?

Have you hooked the disk up to a PC and tested it?

[zose]

Yes, the disk is fine. If I write the command I get the output below which seems to be correct because I have 2 3.5 HDD disks which are 2TB and 1 Usb which is 2TB connected to the Nas:

Have you checked the health of sdb?

# smartctl --all /dev/sdb

You could try writing zeroes to the start of the disk

# dd if=/dev/zero bs=1M count=1000 of=/dev/sdb

then remove the new disk and try adding it again.
