A tour of LVM. This show covers setting up LVM manually, which can be useful since often LVM is setup magically during installation. Hopefully, this overview will clarify what LVM does, what it's capable of, and how you can interact with it. shasum -a256=2a9f63775736f2fd58e97e157f5650643986bd55540194ce2f5b1fc216f999b4

Klaatu continues his tour of all the little packages that are installed on your Linux box. In this episode: JFS, kbd utils, kmod, less, lha and lrzip compression showdown, libcgroup, libgudev, lilo, logrotate, and LVM. Since setting up an array of drives often happens when you are installing an OS, it's worth noting up front that I recommend not attempting to use your installer's LVM setup tool, since, as far as I have seen, they are generally unholy messes. What I do is install the OS on a single LVM-enabled drive, and then add more drives with LVM post facto. Therefore, the starting point of this tutorial is: You have Linux installed on a drive, which is a single LVM volume group. If you have that, boot into your OS, and begin: 1. Partition your un-used hard drive. Assuming you have only two drives in your machine, let's call the first /dev/sdX and the second /dev/sdY (in reality, the values are probably sda and sdb, but to protect you from copy-paste disasters, I use placeholders). First, find out how big your disk is: ` # parted /dev/sdY print | grep Disk ` 2. For the sake of this example, let's say your drive is 1200100MB (1TB) in size. Create a partition that spans the whole drive: ` # parted /dev/sdY mkpart primary 1 1200100 ` 3. Flag it as an available entity in your storage pool. ` # pvcreate /dev/sdY1 ` 4. OK, now you have a drive prepped for use, but we should pause and look at our imaginary setup. In order to add this new drive to an LVM volume group, we need to know what volume groups we have. Your OS installer might have created this for you, or it might be something you very consciously designed yourself. Either way, you can see what you have available: ` # vgdisplay storage ` 5. OK, so we have a volume group called storage. Currently, we happen to know that storage contains only your first drive; the one that you installed your OS onto. But you want to make that bigger by adding a second drive to it. This is called extending your volume group. ` # vgextend storage /dev/sdY1 ` 6. Now we have a pool that has access to two partitions, but we are still not actually using the second partition. A volume group contains logical volumes, and it is to those volumes that you can add disk space by drawing from the available disks in the group. To check what logical volumes you have: ` # lvdisplay ` To check physical volumes for size: ` # pvdisplay ` 7. Armed with a mental map of how your partitions and system are each laid out, you can now extend the logical volume. Let's say that your installer placed /home into its own partition. You would see it as a logical volume, and you can extend its size: ` # lvextend -L +999G /dev/storage/home ` That would, as you can probably guess from the command itself, extend the logical volume containing your home folders by 999Gb. 8. Well, almost anyway. It has extended the space available to the logical volume, but it has not actually stretched the file system across all that new space yet. To make all that extra space readable and writable, you must resize it: ` # resize2fs /dev/storage/home ` Verify what you have just done: ` # df -h /home 1889T ` Your home directory is now nearly 2TB in size, and the fact that the file system spans two separate physical volumes is entirely transparent to the OS. shasum -a256=27e164d61163394c5db669002b14237a87a58f8dfbe01e5b8dfcbc36f265a341

Klaatu tries `pkgsrc` on Slackware, and you won't believe what happens next. But to sum it up: it's super easy to implement, easy to use, and pretty nifty. To get `pkgsrc` on your Linux OS: Download: $ wget ftp://ftp.netbsd.org/pub/pkgsrc/current.pkgsrc.tar.gz Extract it to `/usr`: # su - # tar --extract --verbose --file pkgsrc.tar.gz -C /usr Bootstrap `pkgsrc`: # cd /usr/pkgsrc/ # ./bootstrap Adjust paths: # echo "PATH=$PATH:/usr/pkg/bin:/usr/pkg/sbin" >> ~/.bashrc # echo "export $PATH" >> ~/.bashrc # echo "MANPATH=$MANPATH:/usr/pkg/man" >> ~/.bashrc # echo "export $MANPATH" >> ~/.bashrc Build something: # cd /usr/pkgsrc/foo/bar # make install shasum -a256=d33c41ab7665166611763ff41ca50550fb523d79ac9326b56aae56f03e2c2a98

Linux user, know thyself. It's a new year and a new season, and the GNU World Order is now officially an Ogg Vorbis and Opus cast. Although there is no speex feed now, there is no need to update your feed. The old speex feeds are symlinked to the new Opus feed. In this episode, Klaatu takes a look at all those little files that get installed when you install Linux, like libgmp, libglib, libgobject, libpanel, libusb, and many many more. shasum -a256=5468697f0d58ba413a5038196b41efb8a319e5e66f726ab62468993f67b1ac17
