Reiser and Run

While working through today’s code and test to-do list, I ran out of space on a required SLES 10 file system.   Fortunately, it was LVM-managed, and there was plenty of room in the volume group to stretch this thing.  I vaguely recalled just enough LVM command names (lvdisplay, lvresize) to look up the process.

Extending the logical volume was super-fast, but resize2fs failed with “can’t resize a mounted filesystem!” No way!  This was a 2.6.16 kernel: not exactly hip, but current enough to allow online resizing.

I checked mount points and saw that this was a reiserfs file system.  ReiserFS?!  Sure, that was once the SLES way, but I thought it had been deprecated since the arrest, if not for murder-related reasons, then for security and/or functional ones.  Fortunately, the LVM HOWTO rescued me: it told me to use resize_reiserfs instead, and that worked like a charm.

I’ll try to remember this in case there’s a next time.  If not, this blog post will remind me. 🙂

Just Add Water

I decided to go with Ubuntu 9.10 64-bit this time on my newest development VM.  But when first starting the DB2 9.7 install (db2setup), I got the following errors:

The 32 bit library file libstdc++.so.6 is not found on the system.
32-bit applications may be affected.
The required library file libaio.so.1 is not found on the system.

Those are the standard C++ and asynchronous I/O libraries.  My fingers were already a bit tired from sudo apt-get install‘ing and config’ing the world, but a couple more (with !s:s/… shortcuts) wouldn’t kill me, so:

sudo apt-get install libstdc++6
sudo apt-get install libaio-dev

… and I was off and running.

One of these days, someone will package an “everything you could possibly every need” distro to speed setup.  Why not, disk and bandwidth are cheap.  Until then, maybe I’ll script the whole thing or at least save off my baseline VM.
