Here is my situation, we have an Abit AT7 motherboard with onboard RAID (HPT374). It has worked beautifully for us with FreeBSD 4.7 and then 4.8 for a good 8 months or so serving up NFS and Samba. This morning my /etc/exports looked something like /data6 machine1 machine2 -mapall=65534 /data8 machine1 machine2 -mapall=65534 I then added a line so it looked something like: /data6 machine1 machine2 -mapall=65534 /data8 machine1 machine2 -mapall=65534 /data6 -network 10.10.10 -mask 255.255.255.0 -mapall=65534 I sent a HUP to mountd and everything seemed to work fine. Then I started getting errors similar to: ad4: hard error reading fsbn 242727552 So I rebooted and the HPT374 controller was complaining that the first disk in the RAID-0 configuration failed. I thought this might be a bad disk, but we had an identical system with the same EXACT configuration and we started mountd on that with the same exports file from above. A minute or two later the same type of errors and same complaint by the HPT374 controller about the first disk in the RAID-0 array being bad. I was wondering if there is any, no matter how remote, possibility that by adding that third line to the exports file that the raid-0 got corrupted somehow and if so how to maybe reverse it. I have left everything else intact nothing has changed on the controller side or freebsd config. Just as a note, we are not using vinum, but using the created array (ar0) and formatting that as UFS. Thanks so much for getting thorugh this email! Sumit
