-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Warren:
Sorry to hear that this happened to you after Thanksgiving. Being a bit of a incessant tinkerer myself, I understand the drive to pursue one's own process of trial and error. Sometimes one moves into a new direction sometimes one gets into the jam you're reporting. I found a rather detailed explanation for you which could address your problem by restoring the superblock by resorting or recalling the backup of the superblock which Linux creates for itself. Before I refer you to the article recall that the superblock refers to data structures containing information regarding the hard drive partition which Linux resides on; ext2 or ext3 refers to the filetype that same data is written in. Simply stated, the superblock always needs to be present regardless of the filetype because the superblock comprises everything describing where your data is within a hard drive partition. When an application, process or anything else needs information regarding information regarding a particular file (and remember everything in Unix/Linux is a file) the fastest way to determine that information is to query the superblock. The article also discusses a programmer's preference regarding a "production system" which I'll attempt to elaborate upon briefly. A "production system" can be considered any Unix/Linux environment in which programming projects exist. Even if the only programs you write are explorations into producing "Hello World", within any computer language available in Linux, these projects and efforts are yours and require a solidly tested kernel and associated components for compilers, etc. The article advises against the tendency amongst many consumers/users to acquire the latest version of any program or project or kernel, because getting the latest does not mean that the latest version is free of bugs. Instead acquiring the latest version usually means that the bugs are hidden because they've not been thoroughly tested by a sufficiently large body of persons. This is also why the tendency amongst many is to remain within "stable" releases of a product. Also every Unix/Linux is likewise identified as stable, experimental or leading/bleeding edge. Staying "stable" is not as exciting as "the latest" stuff, but there are certainly a lot less headaches. Here's the article discussing the superblock and a possible means of recovery. If this doesn't work, you may be looking at a complete reinstallation. Of course, hopefully after you read the article you may just choose to stay within YDL 5.0.2 just as TSS released it. http://www.cyberciti.biz/tips/surviving-a-linux-filesystem-failures.html In the meantime, just in case you were interested in a bit more background regarding the Unix File System (UFS) I believed the brief discussion located in Wikipedia here could be useful: http://en.wikipedia.org/wiki/Unix_File_System Good Luck...
