embedded filesystem recommendation

I am interested in finding a robust filesystem for use in an embedded
server system device which will be using a general purpose enterprise linux
distribution. The main purpose is to guarantee filesystem and data
integrity in the case of power cut, not to mention fs check speed.

Can this be done with jffs2 on a standard hard disk? If yes, would an
enterprise linux be happy with the partitions formatted this way. If
no, are there other solutions to suggest which provide this level of
integrity on a hard drive medium?

AFAIK, it is possible to run jffs on a standard disk. But what would
that et you ? There are lots of other journalling filer systems that
provide roll-back mechanism without needing to take care of the flash
internal page structure, like jffs needs to do.

Well, impress me how smart you are. What other filesystems? And what
advantages do they get me?

ext3 and reiserfs come to mind.

Hi David,

to mine too :-). The big advantage of ext3 is, that it can always be
mounted as ext2 without loosing any filesystem-information. So it can
be accessed by any linux version since 0.9 :-). I cant see any
advantages in using reiserfs.

The advantages of reiserfs depend on your needs - for some uses and some
operations, reiserfs is very much faster than ext3.  There are dozens of
comparisons between reiserfs and ext3 (and xfs, and problably others) on the
web, but be careful of bias and rumour - each system has it's share of
supporters and detractors giving different viewpoints.
