    I think you can go to Storage Manager > Internal Storage > Hard Disk and use SMART to check which disk is broken and replace it

    If after degradation files from 2018 and newer are not visible anymore, the array was already degraded in 2018. As a consequence only one disk was upgraded since then, and now that 2nd disk died, and somehow the NAS found back & mounted the old one.

    Can you open the telnet backdoor, and post the output of

    cat /proc/partitions
    cat /proc/mounts
    mdadm --examine /dev/sd[ab]2
