RAID commands

My controller is a 3Ware 9260-8i Docs are here: https://www.broadcom.com/support/download-search?pg=Legacy+Products&pf=Legacy+Products&pn=MegaRAID+SAS+9260-8i&pa=&po=&dk=

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

I put everything on SSD, I might be inclined to move /home somewhere.

SSD configuration

The SSD drives are already configured as RAID 1 so I am sticking with that. There is a small (about 200M) unused partition that I probably intended to hold /boot and the rest is 200+G.

OCZ Revo configuration

There is a fast (well it was in 2012, not by 2019 standards) OCZ Revo 55GBx2 card in RAID 0 used for Docker volumes and fast PostgreSQL databases. It's way faster than the spinning drives.

/etc/fstab entry

# OCZ Revo 110GB SSD on PCIe (/dev/md2)                                                                                                                
UUID=3257ae59-d47f-455e-9695-a46c49de68fc /var/lib/docker/volumes  btrfs defaults 0     1

LSI RAID configuration

As noted in /etc/fstab I have 7 drives with 6 in a RAID 5 and 1 hot spare. They are 5900 RPM drives so this is "cold storage".

# 3Ware/LSI raid controller RAID 5, 6+1 HSP                                                                                                  
UUID=34baa852-2bf0-4905-a1d6-f8c6083fc968 /raid           btrfs   defaults        0       1

Network

• eno1/br0 192.168.123.?
• eno2 unused

Software

• Debian 10
• postfix not exim4

apt install docker-compose net-tools dnsutils btrfs-progs emacs postfix

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.
