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
512 ram
dual sparc2 400's
4 18 gig hard drives
Installing deb woody kernel.
