So, from how i can see, it it ok.

------ Post updated at 09:57 AM ------

So from this i can be sure that files are on the disks? Can I check it somehow? Or this is a good test for it.
The highlighted parts in red shows that the raid is good, you would need to investigate if you see a degraded state.

You should be able to access the files going to the mounting point whether your raid1 is degraded or not. There's some indication that you have done it in /mnt/md0

The samba setup is not particularly related to whether the underneath storage technology is raid or something else.

mkfs.btrfs

MKFS.BTRFS(8)						      System Manager's Manual						     MKFS.BTRFS(8)

NAME

       mkfs.btrfs - create an btrfs filesystem

SYNOPSIS

       mkfs.btrfs [ -A alloc-start ] [ -b byte-count ] [  -d data-profile ] [  -l leafsize ] [	-L label ] [  -m metadata profile ] [  -n nodesize
       ] [  -s sectorsize ] [  -h ] [  -V ]  device [  device ... ]

DESCRIPTION

       mkfs.btrfs is used to create an btrfs filesystem (usually in a disk partition, or an array of disk partitions).	device is the special file
       corresponding  to  the  device  (e.g  /dev/sdXX	).   If  multiple   devices  are specified, btrfs is created spanning across the specified
       devices.

OPTIONS

       -A, --alloc-start offset
	      Specify the offset from the start of the device to start the btrfs filesystem. The default value	is  zero,  or  the  start  of  the
	      device.

       -b, --byte-count size
	      Specify the size of the resultant filesystem. If this option is not used, mkfs.btrfs uses all the available storage for the filesys-
	      tem.

       -d, --data type
	      Specify how the data must be spanned across the devices specified. Valid values are raid0, raid1, raid10 or single.

       -l, --leafsize size
	      Specify the leaf size, the least data item in which btrfs stores data. The default value is the page size.

       -L, --label name
	      Specify a label for the filesystem.

       -m, --metadata profile
	      Specify how metadata must be spanned across the devices specified. Valid values are raid0, raid1, raid10 or single.

       -n, --nodesize size
	      Specify the nodesize. By default the value is set to the pagesize.

       -s, --sectorsize size
	      Specify the sectorsize, the minimum block allocation.

       -V, --version
	      Print the mkfs.btrfs version and exit.

AVAILABILITY

       mkfs.btrfs is part of btrfs-progs. Btrfs is currently under heavy development, and not suitable for any uses other  than  benchmarking  and
       review.	Please refer to the btrfs wiki http://btrfs.wiki.kernel.org for further details.
