The file system type the RAID 1 was originally working with.

Looking at dmesg, as suggested in mount's error message is a good
idea.

Try to omit the explicit file system ("-t ext4") in the mount
invocation above: mount should be able to find out by itself --
unless you positively know that ext4 is right.

For RAID 1 it shouldn't be necessary, AFAIR
