Remove smaller drives from RAID 5 so that larger drives take over

I have a RAID 5 with 6 drives at 38gb and 6 new drives at 148gb running on a netware 6 server Is there a way to remove the 36gb drives from the stripe set and then expand into the 148s?

You can remove one drive at a time and let them rebuild onto the drives, one at a time.  BUT, you're not going to expand the RAID that way.  You'll have 6x110GB of unallocated space you can create another RAID for.  If you want to make this a 6x148GB RAID set, you have to backup everything and then replace the drives and restore data.

If I remove all of the 36gb drives can I expand the 148s with out destory data?
You can't expand the allocated space on each drive to use more than what was allocated originally when you use RAID-5.  As leew said, you have to archive the data, create a new array with the 148GB drives, and then copy the data to the new array.  If your controller supports it, you can keep the original array and add a second array, then copy the data to it.
