RN102 - Rebuilding after disc change - md1 on 1 drive only

 

Hello,

after hdd change in RN102 Unit (FW 6.9.3, 2x WD RED 2TB) Nas says all is OK.

But when i look in PHPsysinfo i see this:

md127 RAID1 (2 disc) - OK

md0 RAID1 (2 disc) - OK

md1 RAID1 (1disc) ??? this volume is on old disc only (sdb2)

Additional Information
Status	                 active
RAID-Level	         raid1
Persistent Superblock 	 available
Registered/Active Disks

 

Is there anything i need to do to corect this state of md1?

How to get expand on new disc? Or can I ignore this state?

Can anyone tell me what to do?

Thank you very much.

    MD1 is the swap partition, so I don't think it's all that critical.

     

    Hopefully mdgm-ntgr will chime in.

      This should be easy to fix via SSH.

      You'd need to start by checking a few things

      # cat /proc/partitions
      # cat /proc/mdstat
