Finally got the RAID1 working.

Hi, just let you know and if someone stumbles in same problem i was able to fix the problem by following measures:

So firstly in busybox i was able to boot while degraded by entering these commands.

Code:

 
(initramfs): mdadm --run /dev/md0
(initramfs): mdadm --run /dev/md1
(initramfs): exit

And to automate the boot when degraded by creating a file /usr/share/initramfs-tools/scripts/local-top/mdadm adding the following to the file:

Code:

patch --verbose --ignore-whitespace <<'EndOfPatch'
--- mdadm
+++ mdadm
@@ -76,7 +76,15 @@
   if $MDADM --assemble --scan --run --auto=yes${extra_args:+ $extra_args}; then
     verbose && log_success_msg "assembled all arrays."
   else
-    log_failure_msg "failed to assemble all arrays."
+    log_warning_msg "failed to assemble all arrays...attempting individual starts"
+    for dev in $(cat /proc/mdstat | grep md | cut -d ' ' -f 1); do
+      log_begin_msg "attempting mdadm --run $dev"
+      if $MDADM --run $dev; then
+        verbose && log_success_msg "started $dev"
+      else
+        log_failure_msg "failed to start $dev"
+      fi
+    done
   fi
   verbose && log_end_msg

EndOfPatch

Then update initrafms with command:
update-initramfs -u
