At work, we have a couple Backblaze storage pods (version 3 with 4TB drives) that we use for backup purposes. They were obtained before my time because quick, bulk storage was necessary to backup our object storage platform, Swift. Sadly, the boxes were deployed in an unsatisfactory manner whereas all 45 drives were pooled together in one gigantic LVM formation, meaning any one disk could die and data loss would occur.
Continue reading ↦Discovered that in recent Ubuntu versions, the following is the “official” way to up and down interfaces cleanly. Edit /etc/network/interfaces adding your entry similar to below: # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 10.1.24.30 netmask 255.255.254.0 network 10.1.24.0 broadcast 10.1.25.255 gateway 10.1.24.1 # dns-* options are implemented by the resolvconf package, if installed dns-nameservers 10.

In short, Time Machine wouldn’t let me encrypt my backups which I dumped on the first partition of my disk. Turns out this is because I used the older MBR partition scheme. These are the requirements in order for that check box to be clickable:
Continue reading ↦This was fairly easy to do: Edit the sources.list or necessary file in sources.list.d to use the new version “qiana” and also utilize “trusty” ubuntu packages: 2. ` apt-get update apt-get dist-upgrade apt-get upgrade ??? Profit! Thanks tecmint!
Booting into the livecd, its pretty basic: Setup networking with “ip addr add” etc.. commands: # ip addr add <address>/<masklen> dev eth0 # ip link set dev eth0 up # ip route add default via <default gw> Set root user password and log in via ssh Do something similar to below, basically create a cloud-config, and call the coreos-install command. ?[~]> sh [email protected] [email protected]'s password: [email protected]'s password: CoreOS (stable) Update Strategy: No Reboots [email protected] ~ # export http_proxy=http://proxy.
Continue reading ↦Fortunately, could only get server via the eval program….btw, I strongly dislike rhel. Via RedHat: yum groupinstall "X Window System" Desktop Edit /etc/inittab for runlevel 5 (change the 3 to a 5) /etc/sysconfig/desktop needs to contain: DISPLAYMANAGER=GNOME DESKTOP=GNOME Install vmware-tools (can do this via cli), mainly ./vmware*.pl (read the INSTALL) Enjoy?
So I don’t usually use a RHEL based machine, but recently was tasked with deploying one on our network. After the normal install process, which I decided to do text based via adding the following to the boot statement for the default installer option (push “e” when it appears): linux text I decided to setup networking later, after the machine was fully installed. On ubuntu/debian based systems, /etc/network/interfaces defines the configuration for interfaces on the system.
Continue reading ↦Just a quick note, I found a fork of unetbootin called TuxBoot. I highly recommend it as it actually launched in Mint, unlike the latest unetbootin which: Doesn’t find usb devices on osx. Won’t even launch on certain linux distros for whatever reason? Tuxboot supports Linux and Windows….and worked for me the first time around:)
