i'm running a 4 disc mdadm RAID5
One drive (sdb) shows a red dot in OMV SMART settings (Popup message: Drive has few bad blocks).
Here a log of Smart-Attributes:
Not so good:
Raw_Read_Error_Rate: 8791 (other discs show 0)
Reallocated_Sector_Ct: 3 (other discs show 0)
Current_Pending_Sector: 142 (other discs show 0)
Should i be concerned? The Raid-Status is clean, all is working fine, except the strange Smart-Status log.
sdb has few bad sectors which are pending. I tried to get the bad block numbers to reallocate these, but Smart health-test PASSED!
Did selftests and they completed without errors and do not show bad blocks in LBA_of_first_error! Why? There are pending sectors!
tune2fs, fdisk need the exact block numbers to reallocate/overwrite pending blocks, but there are no block faulty blocks under LBA_of_first_error
How can i fix the pending sectors without loosing raid5 or data-loss?
