Thanks. I had tried to reboot but the array is still corrupt

Hi all, I had unraid 6.9.1 running on an E3 1230 v2 platform. It worked fine except that read speed is a bit slow capped at around 30MB/s. The array has 6 data drives, 1 parity (serial 6KBM), and 1 NVMe cache. One day the Mobo died and I swapped it for a E5 2683v4 platform. After I restarted unraid on the new platform one of the data drive (NVHK) failed. I tested all drives on unraid using badblocks and none of the disks has any bad sectors; All SMART drives also looked fine. I also extracted the NVHK drive from the unraid server and tested it on a windows based machine, it worked fine. So I put the NVHK back, and put another drive (V28G) as a second parity and tried to rebuild the array. One night later the webUI indicated that the rebuild was done, but data in the array seemed to be corrupted. After a server reboot, webUI indicated that the original parity (6KBM) and the corrupted data drive (NVHK) failed. Data was also corrupted. I tired to remove both V28G and NVHK, but had no luck recovering data. My first priority would be to get the data on the arraies back. Please advise what shall I do.
