Linux Software Raid disk upgrades

by on Dec.16, 2012, under Software

Every now and then you find out that this huge disk you’ve been using — you know, the one that when you bought it you thought “How on earth am I ever going to fill this one up? My biggest game can fit on this disk 100 times!” — … isn’t as huge anymore. Or at least all the free space on it has disappeared and nagios is whining that your disk is full or about to explode.
Some background info: My fileserver here at home has 3 linux software raid arrays (raid-1 mirrors) on top of 4 physical disks. The first and also smallest array is used as root filesystem to boot from into Slackware linux. The second and third arrays are both big and simply for storage of games, music, series, etc.
When I created that first array a few years ago I figured “Hm, 20GB should be enough for a slackware install, right? Well, let’s just make it 50GB to be sure, we have plenty of space anyway on this huge disk“. Back then the ‘huge’ disks were 500GB. Meanwhile those 500GBs have been replaced with 1TB ones, but that array remained the same. Today I have a set of 1.5TB drives to replace the 1TB ones. Not a huge upgrade, but I didn’t have to buy these disks since they came from a server that had its drives upgraded as well. Anyhow, the 50GB partition managed to get filled with over 40GB of stuff that I can’t trash (mostly user home directories). I could move them to a different partition of course, but today we’re going to resize that partition to 100GB and put the rest in the storage partition.

Steam for Linux beta on Slackware

by on Dec.07, 2012, under Software

As I have mentioned a while ago, Steam is coming to Linux. If you cared and filled out the survey back then, you’ve probably already been accepted for the limited beta. In their own words We’ve just expanded the limited public beta by a large amount — in other words, chances are quite big that you’ve been accepted by now. And even if you haven’t, they say you won’t be banned for trying the beta anyway.

However, the beta is obviously for Pokemon OS only right now. But that doesn’t mean we can’t try to get it running under our beloved Slackware Linux, right? 🙂
One catch right now however: you’ll need to have a 32 bit slackware installation lying around. I still have my old one that I can chroot into that I also use for running 32 bit games under wine. If you don’t I’m sure you can do a quick

root@machine:/# mkdir /slackware32
root@machine:/# cd /mnt/slackware-current/slackware/
root@machine:/mnt/slackware-current/slackware# for PKG in `egrep ADD\|REC {a,ap,k,l,n,x,xap}/tagfile | cut -f1,2 -d':' | sed -e 's/tagfile://'` ; do
installpkg -root /slackware32 -infobox $PKG-*.t?z
done
# Takes a while installing packages to your new chroot, after that you can:
root@machine:/mnt/slackware-current/slacware# chroot /slackware32
root@machine:/# echo Now I just need to fix the rest of the configuration of this chroot... like adding a user.

Mind you, you’ll also need your nvidia drivers installed in your 32 bit chroot! “But BenV, I have an ATI/AMD GPU” … yes, you probably have herpes too, go away.
Anyway, since nvidia sucks, the nvidia driver installer will barf because you it detects your 64 bit kernel and you’ll have to install it the manual way:

# This is still in the chroot
root@machine:/# cd /usr/src
root@machine:/usr/src# mkdir nvidia
root@machine:/usr/src# cd nvidia
# Make sure to match your installed version from your 64 bit environment, this one is 310.19
root@machine:/usr/src/nvidia# wget ftp://download.nvidia.com/XFree86/Linux-x86/310.19/NVIDIA-Linux-x86-310.19.run
# Takes a while depending on your connection
root@machine:/usr/src/nvidia# bash NVIDIA-Linux-x86-310.19.run -x
# Extracts to a dir called NVIDIA-Linux-x86-310.19
root@machine:/usr/src/nvidia# cd NVIDIA-Linux-x86-310.19
root@machine:/usr/src/nvidia/NVIDIA-Linux-x86-310.19# ../benv-installer.sh

What’s that benv-installer.sh? A little script that removes the old libraries, copies the new ones in place and checks the libglx symlink.

Anyway, now that the major preparations are done, let’s go fire up the Steam for Linux beta! (I’m sure you can handle the rest of the missing garbage in the Slackware32 chroot that I didn’t mention, like adding a user etc).

# Yes, this is still the slackware32 chroot :)
root@machine:/usr/src/# mkdir steamlinux
root@machine:/usr/src/# cd steamlinux
root@machine:/usr/src/steamlinux# wget http://media.steampowered.com/client/installer/steam.deb
# We don't handle .deb! Let's make it more managable :)
root@machine:/usr/src/steamlinux# ar x steam.deb
# Oh look, a control.tar.gz with nonsense files and a data.tar.gz with stuff we need
root@machine:/usr/src/steamlinux# mkdir pkg
root@machine:/usr/src/steamlinux# cd pkg
root@machine:/usr/src/steamlinux/pkg# tar axf ../data.tar.gz
root@machine:/usr/src/steamlinux# makepkg /usr/src/packages/steam-1.0.0.16-i686-1.txz # This version comes from the control.tar.gz->control file ;)
# Hit enter a few times
root@machine:/usr/src/steamlinux# installpkg /usr/src/packages/steam-1.0.0.16-i686-1.txz

Easy enough. Let’s see what it does! 🙂
Note that you shouldn’t run the steam executable as root. Not that I need to tell you that, right? 😉

Not only did it start with the above output, it gave the following graphical display:

Steam for Linux Beta - first start

Steam for Linux Beta – it tries to update itself after starting it for the first time


After which it errored with the following one:
Steam for Linux beta - first error

Steam for Linux beta – first error


Not that I’m surprised by an error at this point, I never expect things to work from the start 🙂
Taking a look at the console output you can see that xterm isn’t able to start. I guess they need it to run some scripts in or something, so we better make sure it can start properly. The reason is simple: this slackware chroot doesn’t have a proper /dev and especially /dev/pts (and later: /dev/shm) in place. Normally these get mounted a boot, but since you don’t really boot a chroot we have to fix these entries manually. I suggest you make a chroot script for it 😉

# Still in the chroot, as root this time
root@machine:/# mount -n -o mode=0620,gid=5 -t devpts devpts /dev/pts
root@machine:/# mount -t tmpfs tmpfs /dev/shm

There, you should be able to start xterm without errors now. If you didn’t fix the /dev/shm you’ll get another error that looks like this one:

[1207/113507:ERROR:shared_memory_posix.cc(167)] Creating shared memory in /dev/shm/org.chromium.Chromium.shmem.libcef_8194274913974519198 failed: Permission denied

[1207/113507:FATAL:shared_memory_posix.cc(172)] This is frequently caused by incorrect permissions on /dev/shm. Try 'sudo chmod 1777 /dev/shm' to fix.

Anyhow, we fixed it, so let’s try the steam beta again! 🙂

W00t. After logging in and entering the s3cr3t c0d3 because this is a ‘new computer’ according to SteamGuard or whatever it’s called, we look upon our game library. Looks like they added a ‘Linux Games’ entry that’s selected by default.
Steam for Linux Beta on Slackware - Games Library

Steam for Linux Beta on Slackware – Games Library


Well, that’s cool. Let’s see if it works. I ask steam to install Dungeons of Dredmor, hit next a few times, wait a minute orso, and it looks like it’s installed 🙂
The only things that hints we’re not on windows is the weird resolution Dredmor offers (possibly related to me running Fluxbox), but this works great 🙂

Things to note:
* I have a Pulseaudio installation on my slackware32 chroot — sound worked fine for me, but if you’re having trouble it might help to install it.
* Valve seems to have put Team Fortress 2 Beta in my Linux Games list — I’ll have to see how that runs under linux, but it’s 12.2GB so takes a while to leech.
* Carefully read the console output when things don’t work, there may be helpful hints like Steam error: SteamProcessCall(WaitForAppReadyToLaunch)(0xab427c,0xfff3d100,0xfff3cee8) failed with error 17: Cache Write Failure, errno 28 “No space left on device” when your disk is full when trying to install TF2 😉

Anyway, looks like Valve is making great progress in getting Steam to work under linux. Soon things will be running smooth for Pokemon OS and hopefully that’ll open up even more games to linux 🙂
