    There are variations possible, but this should work.

    You should be able to see (part of) your folders in /tmp/mountpoint:

    ls -l /tmp/mountpoint/

    how should i mount second disk?
    Basically the same. But you need to use a different mountpoint

    mkdir /tmp/mountpoint2
    mount /dev/dm-3 /tmp/mountpoint2
    dmesg | tail

    But I don't know if it will happen. Something is wrong with dm-3, and I don't know what that means:

    EXT4-fs (dm-3): ext4_check_descriptors: Checksum for group 128 failed (62833!=0)
    EXT4-fs (dm-3): group descriptors corrupted!
    Rounding down aligned max_sectors from 4294967295 to 4294967288
