no, as dd is a raw block copy of the storage device. i dont actually recommend usinig DD on file systems at all
instead, assuming the raid is freshly formatted, and temporarily mounted as /mnt I would use something like...
dump 0vf - /dev/sda1 | (cd /mnt; restore -rf - )if there's more than one file system on the source, repeat this for each one. note that the source file systems must be unmounted when you do this, hence you would need to do this from a CD boot if its the system drive.
I've always wondered why so many folks use the above construct when a _fast_ less "expensive" solution STM to be something like
cd <your source mount point> ; find . <other params you desire> \ | cpio -p<other params you want> /mnt
Am I missing something? Just old fashioned? Cpio has all the params you want and can be _very_ fast with the righ parameters. Similar to the above dump/restore set I've seen many use tar/untar equivalents.
Just curious is all.
