Hello All,
I have two disks in my RAID 6 array showing: the GPT table is corrupt, but the backup appears OK, so that will be used (/dev/sdd and /dev/sde). The RAID is clean and active at the moment. The doc I read on how to restore the GPT table made me hesistant as one of the steps said it may cause strange things to happen to a RAID array. Can anyone assist with steps to correct this? Thank you.
I'm running OMV 4.1.12 from a flash drive. I have 5 3TB WD greens in a RAID 6 array.
