O got it working by replacing the last line in fstab from 1 2 to 0 0. I guess it had to due with privileges? When I log in I now see my /home/apps directory. I will copy stuff into /home/apps, then unmount it. if my data is not there, I will re-mount it. if my data is there I guess my mounting worked. Would this be a valid test? thanks Marc On Wed, 2006-02-01 at 17:20 -0200, Cleber P. de Souza wrote: > Hi Marc. > > I think you forgot somethings. > After you fdisk a disk, you must restart the system so the new changes > have efect. > So I suggest you follow this steps: > > 1) fdisk sdb setting fd to the partition, as you did; > 2) restart the system; > 3) execute sfdisk -d /dev/sdb | sfdisk /dev/sdc (copy partition > structure from sdb to sdc); > 4) restart again; > 5) run the command to make the raid devices (mdadm ...), as you did; > 6) mkfs.ext3 /dev/md0 > 7) e2fsck -f /dev/md0 > 8) add lin in fstab. > > Ready. > > > > On 2/1/06, Marc Leveille <marc.leveille@xxxxxxxxxxxxxx> wrote: > > I have tried this all morning without success.
