Interesting Meetup Today

Normally we talk about Arduino, LEDs and Raspberry Pis’

Today we talked about machine learning and bugs.

We want to watch a bee have (Mason Bees) and differentiate between it and a pest called Houdini Fly.

It lays its eggs in the Mason bee’s tube and it eats the food.

Mason bees are good in that it helps pollinate.

Mass CostCo Shopping

One pretty big day at CostCo.

Our annual “Bonus” “Cash Back” “Refund” check came in and it was over $500.00

It was nice, hopefully we can make those groceries last.

Also finally cleaned up an error I been having on my FreeNAS server. It was that USB I pulled.

New Small Desktop

Second smallest non-pi x86 based desktop I have (the Brix is the smallest).

Will post more about it, but looks pretty cool.

Fast and runs CentOS 7 too.

New File Server In Production

Where have I heard that before?

So yes, server is up and running and doing OK. This one is a really critical one, does DNS, DHCP, kickstart, home directories. This is the first server that comes up when the house goes dark.

Got it on UPS to auto shutdown as well if needed.

Disappointed With File Server Performance

Just ran some numbers on my new file server, not much of a jump in performance

This is the Old Server

 Running warmup…
 Running a 400MB file write on 5 times…
 Iteration 1:     95.27 MB/sec
 Iteration 2:     72.43 MB/sec
 Iteration 3:     84.90 MB/sec
 Iteration 4:     83.43 MB/sec
 Iteration 5:     92.99 MB/sec
 Average (W):     85.80 MB/sec
 Running a 400MB file read on  5 times…
 Iteration 1:    111.62 MB/sec
 Iteration 2:    113.26 MB/sec
 Iteration 3:    111.91 MB/sec
 Iteration 4:    110.12 MB/sec
 Iteration 5:    110.76 MB/sec
 Average (R):    111.54 MB/sec

This is the New Server

 Running warmup…

 Iteration 4:    112.82 MB/sec
 Iteration 5:    112.72 MB/sec

For yucks this is my FreeNAS server

 Running warmup…
 Running a 400MB file write on 5 times…
 Iteration 1:     16.71 MB/sec
 Iteration 2:     46.09 MB/sec
 Iteration 3:     46.66 MB/sec
 Iteration 4:     46.68 MB/sec
 Iteration 5:     46.35 MB/sec
 Average (W):     40.50 MB/sec
 Running a 400MB file read on  5 times…
 Iteration 1:    116.79 MB/sec
 Iteration 2:    115.78 MB/sec
 Iteration 3:    114.69 MB/sec
 Iteration 4:    115.92 MB/sec
 Iteration 5:    115.38 MB/sec
 Average (R):    115.71 MB/sec

You read that right, the write performance is the worst on FreeNAS

Want even worse news

Performance was better in 2013.

At least on my media server it is slower

 Running warmup…
 Running a 400MB file write on  5 times…
 Iteration 1:     95.58 MB/sec
 Iteration 2:     95.30 MB/sec
 Iteration 3:     93.64 MB/sec
 Iteration 4:     95.42 MB/sec
 Iteration 5:    106.52 MB/sec
 Average (W):     97.29 MB/sec
 Running a 400MB file read on  5 times…
 Iteration 1:    111.93 MB/sec
 Iteration 2:    109.07 MB/sec
 Iteration 3:    111.53 MB/sec
 Iteration 4:    110.52 MB/sec
 Iteration 5:    112.17 MB/sec
 Average (R):    111.04 MB/sec

With that said, I’m not too surprised, because the network was busy when these tests were run.

Going Live with the server tomorrow night when I get home.

On another note, I got a vSpheree 6.0 server upgraded today, that was good, combined the PSC and VC into one, basically going from VC with External PSC to VC with Embedded PSC.

Slowing Down The Weight

Not eating as much as I used to, so I think I am slowing down the weight gain.

But I think I can do better, I know weight can be water weight, but I been hydrating pretty well.

Back to work after 3 days off

Back to work today, got a lot of stuff to do, not much time to do it in.

Stayed a little later than usual.

I am going to work early tomorrow though, still behind, but making up ground.

Configuring New Server

Working on the little things to get the server up.

Letting it bake in so we can see what errors it has, but I think it will be fine.

Going to make it production next week.

New File Server Built

Got the new server built, as I post I am moving all the flat data over. Next is to reconfigure the services.

It runs quite a bit

  • DHCP Server
  • DNS Server
  • LDAP Server
  • MAIL Server
  • File Server
  • TFTP server
  • Subversion Server

Got the raid disks in

Western Digital Red Drives
Low Cost Disk Pack
3ware sees them

Doing the initial sync of data now. I think it will take a while. I expect to have this done tomorrow, but will let it burn in.

Maybe go live next week.

Of all my servers at home, this one is closest to The Linux Home Server project.

The Joys of Pain

After yesterday’s fiasco I needed a break, not a break from IT, but something challenging, I know, how weird yeah.

When most people get burned, they run from fire, I charge after it.

So this is what happened, and this pain was brought me joy today.

Today I went out with one of my daughter’s in search of a SATA controller card.

As an aside, I was also looking for a video card, found one in a GeForce GTS 960 for $60. Not sure if it works, that will be later tonight or tomorrow even, but wanted to note it in future searches.

Went to multiple Recycle PC places, but the final stop was where I found this old, more than a decade, RAID card. I negotated them down from $30 to $10, but make no mistake this card is OLD, it is a 9650SE SATA-II RAID PCIe card.

3Ware 9650SE

The chip says AMCC but it is a 3Ware 9650SE

Why did I buy this card?

  • It’s cheap, $10.00
  • It’s old so support with Linux should be high
  • I couldn’t find a Perc H310
  • Has those SFF-8087 connectors that work in this case
  • PCI-E
  • It’s cheap, $10.00

Oh did I mention I got it for a cheap.

Here’s a huge problem, this thing had no bios, so I could not press ALT+F3 (or is it 3) to configure it.

I had to scour the Internet for Utility to manage this via command line, came across twi_cli, but I had to download it from a 3rd party because 3ware no longer exists

If you are interested, look search on the Internet for 3DM2_CLI-linux_10.2.2.1_9.5.5.1.zip

Here are the checksums I have for the files I found

md5sum  3889909bc63c7f65be89006d22a55b28  3DM2_CLI-linux_10.2.2.1_9.5.5.1.zip
sha256

5354dd539d01163ee6d371da1bd595157dc6db8bfe0907dbb2b920d88cd627a9  3DM2_CLI-linux_10.2.2.1_9.5.5.1.zip

After you download it, you can simply unzip and untar the nested file and look for tw_cli.x86_64, that is the executable you need. If you want to install here are the steps

  • unzip 3DM2_CLI-linux_10.2.2.1_9.5.5.1.zip
  • sh install.sh -i
  • Answer yes
  • You don’t to install the web interface

If you do install the web interface, use https and go to port 888 password is “3ware”

I don’t like it, I just use the cli

Here is where it get’s interesting

Use the tw_cli command line utiltiy

tw_cli info

To figure out what the controller card is, in these examples we will use c9

First turn check if jbod is on, it is normally

tw_cli /c9 show exportjbod

If you need to set it

tw_cli /c9 set exportjbod=on

Now you can add a disk a single JBOD disk, DO NOT ENABLE CACHE

tw_cli /c9 add type=single disk=0 nocache 

Do it for all the disks

But here is the first problem, if you are importing from another disk. You will need to shrink it because parted will complain.

Here is a link on how to shrink it but you will lose the end of the disk because it seems to be where the signature the controller writes to.

https://gparted.org/h2-fix-msdos-pt.php#partition-outside-disk

I would highly recommend making the disks a bit smaller than the physical disks.

I shut down the system and was able to mount the disks without the controller.
