Hey sundudes!
First let me tell you all that I don't use those metatools, that is all
a bunch of balderdash that makes no sense to anybody. The only way to
interact with the system at a lower level is via the command line.
Anybody who is anybody in the UNIX world knows that the command line is
text and therefore superior!
In order to speed up my network connections, I've decided to try some
hard drive style technology by using the RAID5! Raids lets you use the
parity information to account for the corrupt packets inherent in any
network, those darn crazy inodes, and to keep the fat table in order.
This technology will also allow my network connections to go faster and
to finally eliminate that ever-glowing collision light on my switches!
The first thing that I needed to do was to create the state databases to
keep track of what interfaces are playing what roles. To do that, the
command I used was:
# metadb -a -f-c 42 /dev/bge
Ok, that went great! Then I needed to build the raid5s for the network.
This is very easy to do, and I can see why Solaris outsells Linux
because of this. Off the topic a bit, but why did they use RedHat as a
name? I know what a blackhat, a whitehat, and even a greyhat are -- but
what is a redhat? I think it might be communist (like RedChina) since
the GPL is from the old Soviet Union. But I digress. So, to set up the
raid5 on the Solaris, I do is this thing:
# metainit d5 -r /dev/bge0 /dev/bge1 /dev/beg2 /dev/bge3
Ignore any errors that come up from that, as they are just for debugging
purposes only and don't mean anything. You can add > /dev/null if you
want to suppress them!
After that, you need to organize the machine correctly. Part of this
involve creating the network interface on the boots. To do this, simply
follow these simple steps (feel free to cut and paste this if you are
following along):
# echo "192.168.1.100 raid5networked" >> /etc/hosts
# echo "raid5networked" >> /etc/hostname.d5
The only problem with this setup is it does not work. I believe
something is wrong with the plumbing of the network interface on boot
up. I have attempted to fix this by doing:
# ifconfig d5 plumb
Even after that it does not work. I think it might be because of my ugly
cisco switch. I think I should replace it with a new DLink managed solution.
I tried to debug this in the obvious ways. Too bad I am not on Solaris
Express, or I could take the fast line to the dtrace and be done with it
but good! Anyways I did this thing:
I need to create a dubugged project for it:
# projadd -u billy raid5it!
Then watch the audits:
# tee ifconfig plumb d5 |praudit| grep -i WARNING | grep -x `pgrep
praudit` > /tmp/errors
From that I see that some dumber installed Damien Reed's ipf. Heh, that
was a mistake for them! Everyone knows that was pulled and replaced with
pf because Reed was putting trojams into the kernel space to pull
packets for the Russians! I had to remove it:
# rm -rf /dev/ipf
# cat /etc/system | sed 'r/ipf/gotya!/' > /etc/system
But then after I rebooted, I can't get it up. It says invalid system
map. Any one know what is wrong? I opened a ticked with Sun Sliver
Support, but I don't trust them cause their call center seems to be from
England and I know that they are still mad at us for seconding the
French Navy to win our war for us against the red-coats. So I thought I
would turn to the good sunhelpers on this list!
Help little old Bill out here a bit... could you please?
P.S. Check my bloglog! http://www.bilano.biz/ -- I wrote a neat greylist
app for postfix, too, dudes!
