51.6.3 Recovering a Corrupted System
There are several reasons why a system could fail to come up and run properly. A cor-
rupted file system after a system crash, corrupted configuration files, or a corrupted
boot loader configuration are the most common ones.
SUSE Linux Enterprise offers two different methods to cope with this kind of situation.
You can either use the YaST System Repair functionality or boot the rescue system.
The following sections cover both flavors of system repair.
Using YaST System Repair
Before launching the YaST System Repair module, determine in which mode to run it
to best fit your needs. Depending on the severeness and cause of your system failure
and your expertise, there are three different modes to choose from:
Automatic Repair
If your system failed due to an unknown cause and you basically do not know
which part of the system is to blame for the failure, use Automatic Repair. An ex-
tensive automated check will be performed on all components of your installed
system. For a detailed description of this procedure, refer to
Repair"
Customized Repair
If your system failed and you already know which component is to blame, you can
cut the lengthy system check with Automatic Repair short by limiting the scope of
the system analysis to those components. For example, if the system messages
prior to the failure seem to indicate an error with the package database, you can
limit the analysis and repair procedure to checking and restoring this aspect of your
system. For a detailed description of this procedure, refer to
Repair"
Expert Tools
If you already have a clear idea of what component failed and how this should be
fixed, you can skip the analysis runs and directly apply the tools necessary for the
repair of the respective component. For details, refer to
