Hi guys, i changed a raid controller that was in JBOD to an HBA card, I then created a new configuration with all the drives in the right slots as read in here, i misclicked the Parity is valid checkbox and started the array without the checkmark in the checkbox.
after the switchit told me 4 of my drives where in an unsupported partition layout. When I scrolled the page I read the parity check was working, I immediatly stopped the array in panic.
I read that I needed to unnasign a single drive start the array to emulate the drive, stop the array assign the drive and let the rebuild goes one disk at a time. so I tried it. I unnasigned a drive. started the array and check the box the parity is valid. the disk didnt emulated, I realised then that the partial parity rebuilt probably screwed the parity disk. so now i may have an invalid parity drive and 4 data drive that are unmountable.
so now I feel like I'm screwed, do I have a way to save my data? should I put my old RAID card back in the server and try to rebuild parity first?
-4 drives were already hooked to the mother board, parity was one of it.
-4 were on the JBOD raid card,
1 pcie ssd for cache
i'm panicking,
i think I may need to do a new config with the 4 good drives parity + 3 HDD
-new config 4 detected drives.
-start array
-let parity rebuild
-install unmountable drives pluggin,
-mount drives,
-move data from a disk to array
-add the disk to the array, and format it,
-let parity rebuild,
-repeat for 3 next drives.
is that a good plan? it will be a long plan. but i want my data back
