Hi lfrye,

I agree with StephenB. Replacing the faulty drive will be the best option.

Hi lfrye,

I just saw your logs and it looks like disk 2 is already marked as faulty.

md127 : active raid6 sde3[0] sda3[8] sdb3[5] sdc3[6] sdd3[7] sdi3[3] sdh3[2] sdf3[1](F)
17552488704 blocks super 1.2 level 6, 64k chunk, algorithm 2 [8/7] [U_UUUUUU]

Checking the disk_info.log, there are 5 current pending sectors on your disk 2.

Device: sdf
Controller: 0
Channel: 1
Model: WDC WD3000FYYZ-01UL1B1
Serial: XXXXXX

ATA Error Count: 0
Reallocated Sectors: 0
Reallocation Events: 0
Spin Retry Count: 0
Current Pending Sector Count: 5
Uncorrectable Sector Count: 0

RAID 6 has 2 parity drives but if one fails, it is still degraded. The volume becomes degraded whenever one drive outside of the total number is out.

  Hi JohnCM_S,
  
  Thank you for the info. Is there a way to fix this issue or is a drive replacement the best move forward?

    Replacing it is probably the best option.
