RAID commands

My controller is a 3Ware 9260-8i with firmware 3.27.00 The controller is 1000:0079, MegaRaidSAS http://hwraid.le-vert.net/wiki/LSIMegaRAIDSAS

The drive is a WDC WD30EFRX "Red".

I have not gotten the RAID command line program running yet on this OS (Debian 8).

At boot time, you can type Ctl-Y when prompted to bring up a command prompt. "$" There is no "help" option -- I found some scant documentation online, here are references

When a drive failed, I had to turn off the ALARM! It's LOUD, you can't miss it. It beeps once per second to tell you a drive is gone.

I have only one controller so I can use -aALL or -a0

Silencing the alarm

AdpSetProp AlarmDsbl -a0

Replacing the drive

Hardware

• Supermicro server case
• Supermicro motherboard X9 something or other
• Intel(R) Xeon(R) CPU E5-2650 0 @ 2.00GHz processor (8 hyperthreaded cores, appears as 16 cpu's) 63998.21 BogoMIPS
• 32GB RAM: 4x KVR16R11D4K4/32 DDR3 1600 Registered ECC (there are 4 empty slots)
• 240G SSD x 2 for the OS Corsair Neutron GTX (2012)
• 3Ware LSI RAID controller good for 8 drives
• 7 WDC 3TB 5900 RPM Red disk drives

There's an "OCZ Revo" card which appears as 2 55G drives for SWAP space, because I have no idea what else to do with that thing. :-)

SSD configuration

The SSD drives are already configured as RAID 1 so I am sticking with that.

LSI RAID configuration

Currently all 7 Red drives are in a RAID 6, which gives a total of about 14TB available space (before formatting). The problem is the Red drives are only 5900 rpm and I happen to have some spare unused 7200 rpm drives.

I could do two arrays and two logical drives or I could mix the drives in one array.

• RAID 1 (2 2TB 7200 rpm drives) + RAID 5 (5 3TB drives) = 14TB
• RAID 10 (4 mixed speed drives) + RAID 5 (3 3TB drives) = 10 TB
• RAID 50 (6 mixed speed drives + 1 spare) = 6TB

I think that mixing fast and slow drives will pull performance down so my inclination is to go with the first option, putting PostgreSQL onto the RAID 1 and using the RAID 5 for bulky things like backups and media.

Network

• eth0/br0 192.168.2.236 -- used by Dart and KVM virtual machines hub and quail
• eth1 10.10.10.1 -- unused presently

Software

• Debian 10
• postfix not exim4
• docker community edition

Postfix

Email is supported via Wildsong at the moment. That is, mail originates @wildsong.biz

• smarthost using gmail, because I use gmail for the Wildsong and Geo-CEG domains.
• sasl auth is needed to talk gmail

Mediawiki + MySQL

DEPRECATED

I used to install these here. My wiki moved to the cloud long ago. If I did install here it would be Dockerized.

PostgreSQL

I run PostgreSQL and friends in Docker now. The pain of PostGIS installation on the host outweighs any minor performance gain. I do have to make sure the data ends up on the correct logical drive on the host!

DEPRECATED

Anyway if I wanted to install on the host it would require adding a repo to get a more recent version. In days of yore the commands would have been

echo "deb http://apt.postgresql.org/pub/repos/apt/ wheezy-pgdg main" > /etc/apt/sources.list.d/pgdg.list
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add -
apt-get update 
apt-get install postgresql-9.4

2015-Feb-27

I packed up Dart last May (2014) shortly after re-installing the operating system and switching to Debian. Now I am trying to pick up the pieces. There is no Web server right now! Zow! How can that be?

I do remember I gave up on CentOS when I found out how impractical it was to try to run my own copy of ESRI ArcGIS Server after I lost (free) access to a developer license.
