As part of my current research, I am doing some investigation of file
systems which are resistant to system failures. In general, systems
which buffer accesses tend to have inconsistent file system entries if
the system stops at a poor time in relation to a system "sync." Most
systems require the use of a check program (eg., fscheck) in the event
of an unscheduled shutdown. A resistant system is one which requires
minimal (no) special effort to bring it back into a consistent state
after a crash.
I have some references to file system recovery methods and the design
of resistant file systems, but I'd like to know if there are any I've
missed. I would appreciate any references to work in this area. I'd
especially appreciate pointers to case studies of real file systems and
their methods of handling crashes. Any other information anyone might
care to provide will be appreciated.
Please reply by mail rather than posting replies. Thanks in advance.
