Sort of. The steps you'll need are:
1) Resize partitions (usually a drop & recreate step - this doesn't
affect the data though).
2) Force the OS to be aware of the new partition sizes - either a
reboot or using partprobe.
3) Grow the array (mdadm --grow) - check the manual page for details.
4) Resize the filesystem (resize2fs).
There shouldn't be any need to drop & recreate the journal (I've never
done anyway - I guess it may be needed if you want to resize it).
HTH,
