Hi all, I have a configuration with 4x4TB WD disks and one of them present some smart error, I opened an RMA and before sending a new one wd asks me to do a low-level format and verify If the error persists ( you can see smart data attached).
For first step I powered off my OMV box, removed the sata cable and started again OMV with 3 disks, I expected to see my raid configuration working in degraded state but in RAID management I cannot see my RAID configuration and obviously my SMB share dows not works. Reverted the process everything is good and clean.
How can I do this check? I would like to do It while my RAID configuration continues to work in degraded state, and when I will replace the disk ( with a new one or mine fixed with low-level format ) restore the 4-disks RAID configuration.
