What was to be a quick Orac upgrade, was a bit more.

The other day when I was shopping for quieter 120mm fan for my TR5M-BP enclosure, I thought about getting a bigger/better fan for Orac. I knew there were holes to take a fan larger than the one that was current in it.

Though I guess I should've measured or something. Because after I had the old fan out and things apart...found the fan that I had gotten was too big. I started putting things back, when I decided I might as well do the other things I wanted to do.

First the mirror of the internal RAID1 was failing.....the original had failed early and I exchanged it for a recertified one from Seagate and put in a different drive. Interesting that the warranty of the replacement drive seems to have expired, while the warranty of the original ST3500630AS is still active.

I was trying to decide if I buy a new 500GB drive, or put the recertified one in. Seeing as I had things open...and I hadn't bought a new drive yet. I put the recertified one in. I also had that project to put in a PCI compact flash card in. Though I hadn't gotten the desired compact flash card, yet. But, did have a 16GB 133x card sitting around...so I decided use that for now. The 8GB 600x card will have to come later.

I then put everything back...and watched to take forever to boot....the PCI compact flash card seems to slow the boot down a lot, and I don't know why. Maybe I don't want it now. May need to rethink the experiment. Perhaps when I get a correct sized fan and open it up next.

And, then it didn't....guess in everything, I forgot to reconnect the case fan. Oh well, the silly clamp does a lousy job holding the unsupported slot covers in place...and putting cables back in, the bracket pushed in. They probably knew that since the blank has a hook on it, but the eSATA bracket is a regular kind...but no room to slip a screw in to properly secure it.

So, opened things up and then tried it all again.

Oh yeah, while I had it open the first time, I noticed the CPU heatsink was all full of dust, so I blew that out.

Well, things came up slowly....of course the boot RAID1 was degraded. I then sfdisk'd the new drive, and added it back to the md0/md1....should be done in an hour or so (from now, not when I added it...)

And, then went to fiddle with the compact flash card as an external journal of an ext4 filesystem. Forgot that I was originally playing around with the idea of external bitmaps when I had gotten the idea for the compact flash....but concluded that it wasn't going to work, there's no way to have a filesystem exist during that stage of boot. Not sure if an external journal helps with performance or not....might have been something back when I was doing RAID5/6....but not sure its important enough with RAID10. Don't really have any way to measure if it makes any real-world improvement to what I'm doing.

Meanwhile...I updated cacti, the card shifted all my drives around.... And, seems the CPU is now running a bit cooler than it was before....but the GPU is running hotter than before.

Guess clearing the dust out of the heatsink was good, but adding the PCI card was bad.

I think keep things cool is more important than the external journal experiment...so I will probably yank the compact flash card out when I get the new fan. Wonder if a PCI slot cooler would be something I put in instead?

The Gumby Torture has ended

That is Gumby was torturing me!

It all started around May 13, 2010....and could ended around...sometime back in April, 2011...but had to let it drag on to today...July 23, 2011.

Gumby had been torturing me more and more lately....largely because when I upgraded it in May 13, 2010...it became my second fastest system at home, and my fastest Windows XP box. Ole TARDIS was only a Pentium 4 3.2GHz w/HT. While new Gumby is a Pentium D 3.4GHz.

Though while TARDIS was still my main Windows XP system, I largely kept Gumby's role the same...though it did pick up a few things the ole Gumby didn't do, due to it having more juice and being less cluttered in its registry and driver hell. Like a new DVD burner, or running a few more CPU and/or memory intensive apps (things that didn't work to well on P3-933MHz and/or only a max of 512MB...)

But, the problem with new Gumby was that its a legacy free box. No PS/2 mouse or keyboard ports (though it's strange that I can still buy new systems that have one or two PS/2 ports, something about the reliability of PS/2 mouse and/or keyboard over USB probably... this KVM switch was kind of holding up whether or not I would be requiring PS/2 ports on whatever mobo I decide to build the new LHAVEN around.)

I had gotten USB PS/2 adapters to keep using my old keyboard/mouse and KVM setup on Gumby (though the keyboard and mouse have upgraded a few times since the Trendnet TK-408) Also, I think the mouse has always been a USB kind with a PS/2 adapter. Originally a ball type, now an optical type....some day I'll get some laser mice here and there...

Problem was that the USB PS/2 adapter was less than reliable or usable. I was still using the Kingwin one that I got to start with new Gumby. Which worked the best, except that every now and the the mouse would stop responding. I could have to stop using the mouse for a while, and it had to be absolutely still during the stop....and then something would reset and it would work again. I had tried a TrendNet, thinking it would go with the KVM....but switching away and then back on the KVM would cause the scrollwheel functionality to go away, and that required me to unplug/replug the USB adapter to get scrollwheel working again.

I also tried a PCI PS/2 card, but found that internally was just another USB PS/2 adapter...just in a slot consuming form, plus it didn't get along with the other PCI card (firewire, and I use firewire external storage on Gumby)...also it exhibited the same problem that the TrendNet USB PS/2 adapter did, except that its a little harder to unplug the card to reset it at will...

So, I stayed with the KingWin and set my sight on a KVM.

Now instead of subjecting some poor random forum to a long rambling thought, I will try to consolidate those things into this blog where they can be more easily ignored profess to be collected thoughts from my mind.
