Samba Shares Not Accessible On RAID Array

view story

http://www.linuxquestions.org – I just finished setting up a RAID5 array with 3 new 1.5TB hard drives using mdadm. I spent the last 5 days trying to get the RAID array working. Everything is up and running now except I have not been able to share folders on this drive using Samba. I can share files in my home directory and on my NTFS drive, but not the RAID array. I am trying to access the shares from a Windows Vista PC. I can see the folders, but I can't access them. The RAID array is formatted with ext4. I am using Ubuntu 10.04 64bit using the Samba configuration tool in Nautilus. I gathered all the relevant info (HowTos)
