Maintainence Operations for Linux
A lot of users know how to perform maintainence on Windows systems, using maintainence tools such as Scandisk, Defragmenter, Registry Checker, or the Norton equivalents such as Disk Doctor, Speed Disk and WinDoctor.
I've read that the nature of Linux filesystems is such that they do not require defragmentation. But surely a disk health checking program or system file checker should be run regularly. What are the common system utilities for Linux and where can I get them? I'm using SuSE 8.2, so if there's anything in particular I should know, please tell me.
