Well, I thought that the introduction of the ext3 (and higher) file systems had stopped all of the problems of disk crashes and mangled filesystems on linux.
But, after a few years of reliable operation the root filesystem on my home server (my old Fujitsu Siemens laptop) seems to have mangled.
The symptoms were....not booting - you get the 'Starting up......' message during boot then the system appears to hang. But if you listen carefully you hear that the disk is actually doing something. So I left it for a few hours.....
When I came back to it there was a 'failed to mount /dev/sda1' type error message, with an option to skip mounting or manually fix it.
I went for manually fixing it, because not mounting the root filesystem will not get me very far.
This dropped me into a single user shell.
I ran fsck and it said that an Inode has illegal blocks. I selected the option to clear them...and again said yes when it asked me again.
It then said it was restarting e2fsck from the beginning, and spent quite a few minutes checking....
Then at Pass 2 fsck said it had found a deleted or unused inode. Again I said 'y' to the 'Clear?' question....
Then lots of offers to fix things (to the extent that I just held my finger on the 'y' key...)
Then fsck announced that it was complete and I should re-boot linux. Re-ran fsck and it announced that /dev/sda1 was clean, so re-booted.....but booting is taking a suspiciously long time.....like it has been trying for 10 minutes and hasn't got past the boot up splash screen...I'm going to need a plan B...
Well, I don't know what the problem is. Tried booting off a USB memory stick, and the disk checks ok and mounts, but the boot process just hangs. I decided I had spent too long on this so it is currently installing Ubuntu 10.10 on the disk instead, so can't try any more diagnosis!
Descriptions of some of my geeky projects in case I need to remember what I did in the future.

Emacs Drupal Mode
I am trying to learn how to write Drupal modules for a new map rendering on demand web service (a bit like townguide, but distributed with a separate front end and rendering servers).
First thing is to get emacs23 working with php and drupal modes - the instructions here give me obscure errors about c-lang-def only being used in a file. After a bit of hunting on the internet I found it is a problem with Emacs V23, and a simple work around is to put the php-mode.el and drupal-mode.el files in ~/.emacs.d, then add the following to ~/.emacs:

With that in my .emacs file, loading a .php or .module file starts php or drupal mode - success!; make sure the target directory is on your load-path(add-to-list 'load-path "~/.emacs.d")(autoload 'php-mode "php-mode" "Major mode for editing php code" t)(autoload 'drupal-mode "drupal-mode" "Major mode for editing drupal php " t)(add-to-list 'auto-mode-alist '("\\.\\(module\\|test\\|install\\|theme\\)$" . drupal-mode))(add-to-list 'auto-mode-alist '("\\.\\(php\\|inc\\)$" . php-mode))(add-to-list 'auto-mode-alist '("\\.info" . conf-windows-mode))
