Dmesg should show something like this if you had a raid1:
md: raid1 personality registered as nr 3
md: Autodetecting RAID arrays.
md: autorun ...
md: considering hdc1 ...
md:  adding hdc1 ...
md: created md0
md: bind<hdc1>
md: running: <hdc1>
raid1: raid set md0 active with 1 out of 2 mirrors
md: ... autorun DONE.

If you built it with disk druid it's pretty easy to get raid0
accidentally since that's the drop-down default and you have
to change it for raid1.

And if you omit the -t ext2?
