bitfeniex prodigy with 7 hard drives

I bought this bitfenix prodigy case for about $30 off craiglist, someone didn’t like that it was white, and for $30, couldn’t be beat for this case. As it was retailing for about $80 at newegg/microcenter. I was going to build my girlfriend a new PC and thought ITX was the way to go, after building my own gaming rig on ITX, but using an SG05 ( linky to build ). We went to go look at some monitors at mirceoter, and ended up coming up with a sweet touch screen Dell for her. Nice and neat, and it saved us $1500 from buying an imac, LOL!

So what to do with this case, well, my current NAS was about 3~ years old, had about 2TBx7 HDD’s, and was running JBOD, so nothing fancy. It was a neat little water cooling server in an Antec 300, but I wanted to do something different. I actually had 7 WD 2TB RE4’s laying around not doing anything, so I thought lets build an awesome ITX NAS box! So here we are, throwing together a 7 HDD + 1 SSD NAS box running Windows 7.

I love building PC’s, and I love the fact I do it without cutting, or modding (maybe someday i’ll cut and mod), but I like to keep things stock as possible.

I purchased:

Adapec 5805 off ebay for $100, which has 2 8087’s internal, so I could use 2 fanouts for at least 8 drives. It also has 512MB of onboard memory for the raid 5 I wanted to do. Kicker was it came with a working BBU!

I also snagged a 150mm PSU that I read would fit nicely: Seasonic 360W 80PLUS Gold ATX12V Power Supply SSR-360GP
I got a Intel Pentium Processor G3220, nothing fancy, but it is a slight upgrade to my Q9550 that the server is currently running. No worries though, as I need ZERO cpu to RDP and just make sure everything is hunky dory.
I got a ASRock H81M-ITX, which is my first ASRock mobo, so far so good running this thing.
Couple with 4GBx2 DDR3 I had to purchase as well.

So far i’ll be using the intel CPU cooler, and might swap it out for something decent if I find this thing’s too loud.

I got some molex to SATA power adapters, as the PSU only came with 5 SATA power connectors. I also got some 8087 fanout cables I did not have, ran about $15 bucks for the 2 8087’s, and $10 for the 2x molex to sata connectors.

Swapped out the stock bitfenix brushless fans (model BFF-SCF-12025KK-RP) for my scythe SFLEX SFF21G’s hooked up to some devolts to 9v, so they’re nice and silent. I also purchased a nice bitfenix spectre 230mm fan, threw it up front to see it push some air. If this does not work, i’ll grab a 140mm or 120mm scythe i’ve got laying around and use that. I don’t need a LOT of airflow, but the more I can get while keeping silence would be great.

Here’s what 5 of my 6 drives look like … the SSD and other 2TB are in the 5.25″ bay.

I had one problem where I realized the 8087 connectors are a little tight … so I am not snapping in the 3 bay disk set as to not stress the card. This is what it looks like snapped in/stressed:

This is how i’ll leave it:

Windows 7 – Windows cannot be installed to this disk

I was trying to install windows on my new ASRock H81M-ITX motherboard and for some reason loading windows 7 pro 64bit to my OCZ agility 2 I got this error message:

Windows cannot be installed to this disk. This computer’s hardware may not support booting to this disk. Ensure that the disk’s controller is enabled in the computer’s BIOS menu.

BIOS saw 60GB SSD, the windows installer tool saw and let me format 60GB SSD, so if you are in my shoes and sounds similar, what I did to fix it was go to BIOS, enable SMART, DISABLE EXTERNAL (this seemed to do it), and enable HOT PLUG (not sure if needed, but I did enable).

Hope that helps!

Could not open external command file for reading via open(): (13) -> Permission denied in nagios v4.01

I ended up getting this in my nagios.log, the fix was to change the permissions on the rw file!

chmod 777 /usr/local/nagios/var/rw/nagios.cmd

Directory index forbidden by Options directive: /var/www/html/

I was receiving this error in my nagios apache log:

Directory index forbidden by Options directive: /var/www/html/

to fix this, I just did touch index.html to /var/www/html It creates a file in the directory that is empty. I found this safer then turning on indexes for my nagios install.

How to delete all mail in queue for cPanel exim

I ran into an issue where a user was spamming and queue up thousands of email in our cPanel server. To clear it out, I did this:

/etc/init.d/exim stop

exim -bpru | awk {'print $3'} | xargs exim -Mrm

or

exim -bpru|grep frozen|awk {'print $3'}|xargs exim -Mrm

/etc/init.d/exim start

I had about 120k emails in queue and it took about 20 seconds to remove them all. If you want to fine tune it, you can have exim delete only specific emails in queue:

grep -lr 'a certain string' /var/spool/exim/input/ | \sed -e 's/^.*\/\([a-zA-Z0-9-]*\)-[DH]$/\1/g' | xargs exim -Mrm

Credit to: http://bradthemad.org/tech/notes/exim_cheatsheet.php
 

To delete frozen emails from a specific email address:

exiqgrep -i -f luser@example.tld | xargs exim -Mrm

If you just want to delete mail queue directories, sometimes faster delete:

/var/spool/exim/input and the /var/spool/exim/msglog directories

internal server error with CSF (Config Server Firewall) in cPanel after upgrade in cPanel

So I was receiving this error after cPanel upgraded:

Internal Server Error

500

No response from subprocess (/usr/local/cpanel/whostmgr/docroot/cgi/addon_csf.cgi): subprocess exited with status 2

 

This did not fix it:

 

/usr/sbin/csf -x
/scripts/perlinstaller --force URI
/usr/sbin/csf -e
/usr/sbin/csf -u

If that doesn’t work this will:

 

curl -s configserver.com/free/csupdate | perl

How to move files that are older then x days in linux

I found this useful:
sudo find ./* -mtime +2 -exec mv {} /hosting/dropbox/ops/user/client/ \;
breakdown…
./* is the current directory, including all files, but you could use full path.
mtime +2 is 2 days old
mv is the command being executed
and after the brackets is the directory the files are moving to

Can Dell PE860 (power edge 860) run 3TB drives on the motherboard SATA?

I found out the answer is yes! I have hooked up 2 3TB drives into the onboard SATA and was able to successfully raid 1 them within Ubuntu 12.10. I was not able to do this with the Perc raid controller, as it only saw 2.2TB.

Microsoft Office 2013 PRO ISO/IMG Direct Downloads

I needed these for a retail key I received from my employer for $10, so these were useful, as I did not want to install the cheap software they had to go and download the IMG.

Fatal error: Allowed memory size of 134217728 bytes exhausted – MySQL error – PHPMyAdmin

I had a client trying to import a 200M zip file to phpmyadmin to import into his MySQL database, he kept receiving this error:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 201380904 bytes) in /usr/local/cpanel/base/3rdparty/phpMyAdmin/libraries/zip_extension.lib.php on line 65

It ends up that phpmyadmin is using its own php.ini config, and defaults the memory size to 128M.

Edit the file : /usr/local/cpanel/3rdparty/etc/php.ini.dist

there is a line that says memory_limit, change that to what you’d like. I changed mine to 264M.

You will want to restart cPanel as well:

/etc/init.d/cpanel restart

You will lose this setting upon reboot, so if you want to keep it, you will want to run this:

echo "/usr/local/cpanel/3rdparty/etc/php.ini.dist" >> /etc/cpanelsync.exclude

This will exclude the file when it goes to sync/update with cPanel.
