I installed CentOS 8 in my old Dell T610 hardware RAID1 server, with driver download from https://elrepo.org/linux/dud/el8/x86_64/.
It all worked well, except today my machine lost power and can't start any more.
I try to start rescue with no success (can't find the hard drive on rescue). I pull off one of the RAID 1 disk, and plug into my other CentOS 8 machine, but it won't mount (/dev/sdc), as shown the picture. /dev/sdc1 and /dev/sdc2 can mount, but /dev/sdc3 won't mount and it is where the data have been stored.
I did google search the whole day and followed many different threads, but never worked. Please help. Thank you!
