okay here is my problem...I installed a software
Raid-5 on mybox last night. Here is what I did. I downloaded
and installed raidtools2 and mdadm. Do I need both? Next I wrote my
raidtab file. Here is what it looked like:
raiddev /dev/md0
raid-level 5 nr-raid-disks 3 nr-spare-disks 0 persistent-superblock 1 parity-algorithm left-symmetric chunk-size 32 device /dev/sda3 raid-disk 0 device /dev/sdb1 raid-disk 1 device /dev/sdc1 raid-disk 2 I placed this in the /etc/
directory.
I typed the command:
mkraid/dev/md0
It proceeded to start copying data across the 3 drives. I received no errors during this process. I let the machine run for a while. Should I have received a message when it was completed? I then went back and logged out of root and was going to log in and do a normal shutdown. It would not let me log back in. It would not let me do anything. I powered it down by the power button, and when I restarted, I get the error "Fast Data Access MMU missing", and it won't go any farther. Can anybody give me an idea of what happened? Do I need to make the drives look identical partition wise with Linux/swap size or do I need to make them Linux raid auto, or LVM Linux? Do I need to install the raid-5 drivers at the start of the system install, or is that useless in my case? System specs: Sun Enterprise 250
