October 18, 20232 yr Please, i need help with my array. I did a mainboard swap and now my parity disk and one data disk are HPA "infected". Parity disk is now too small and the data disk is now unmountable. Is there a way to solve this problem without data loss? I already did a lot of research regarding hpa removal (hdat2, hdparm) but I'm afraid of losing data.
October 18, 20232 yr Community Expert Solution First go into the board BIOS and disable Backup BIOS to HDD option or similar, then see here to remove the HPA: https://forums.unraid.net/topic/10229-hpa-aka-why-are-two-identical-drives-different-sizes/?do=findComment&comment=101379 Why is parity disabled?
October 18, 20232 yr Author Bios to hdd is already didabled. Parity is disabled because the disk cannot be assigned as parity disk due to the smaller size. So is it possible without data loss?
October 18, 20232 yr Community Expert 7 minutes ago, masodes said: Parity is disabled because the disk cannot be assigned as parity disk due to the smaller size. Correct, but it would show as wrong, not as disabled, to be disabled you must have started the array without it.
October 18, 20232 yr Author Yes, i think so. I've successfully removed hpa from both disks with hdparm. Parity disk is assignable again. Data disk showed up as wrong. So i made a new config that looks same as before and i started the array. Parity-Sync is now in progress. Looks like all the data is still available. 😃
