You don't mention this, but did you change your /etc/raidtab file to
indicate that hda was no longer a broken disk, but a live part of the
array?

You probably didn't use the -p switch when you copied, so you applied the
umask of the root user to all files you copied. Those permissions are
likely too restrictive. Check the original partitions on hda, if they
still exist. If the permissions are different, then you'll need to change
them.
