Intel VROC software RAID5 failed after single disk failure

Hi,

 

We have a 8 NVME drive Raid5.  One drive failed so we replaced it.  I placed the new drive into the server and it did not rebuild automatically.  

 

Intel VROC states that the 

Volume0,  Raid5(Parity)  is degraded.

 

I have the option to rebuild using the new drive but am afraid I will loose all the data.  Is that the proper steps to recover the RAID5?

 

 

sudo mdadm --detail /dev/md126


/dev/md126:

Raid Devices : 8
Total Devices : 7

Failed Devices : 0

Running the command lsblk  shows all the 8 drives are showing up.  nvme8n1 was the bad drive that I replaced:

nvme5n1 259:5 0 7T 0 disk
nvme2n1 259:6 0 7T 0 disk
nvme4n1 259:7 0 7T 0 disk
nvme3n1 259:8 0 7T 0 disk
nvme6n1 259:9 0 7T 0 disk
nvme9n1 259:10 0 7T 0 disk
nvme7n1 259:11 0 7T 0 disk
nvme8n1 259:12 0 7T 0 disk

 

Thanks for any help!

hey @Spacely , after replace the new drive, its may need kick start the rebuilding and once rebuilding completed only then the RAID5 back to normal state.

 

Hope this helps...
