File systems - Whats better - a few questions.
Hi; Which file system is better, reiserfs or ext3? I think its time to clean install my system (SuSE 7.2) as some parts are in a bit of a mess. What about encryption for my file system? Any drawbacks? -- ------------ Darren Harmon http://users.breathemail.net/darren.harmon1/

reiserfs has had more real-life testing since it's been available longer. It's faster for small files and uses your available disk space better since it isn't hampered by the traditional one block-one file paradigm ext3 offers a smooth upgrade from ext2 since it basically *is* ext2 (it can be cleanly mounted as ext2. You just won't have the journalling) with a few of the previously unused bits used for journalling. You can also use it to journal data, reiserfs only journals metadata. You should also evaluate XFS from SGI and JFS from IBM. They're both excellent filesystems used for years in Irix and AIX respectively. That doesn't mean their linux implementations are fault-proof since the port has a lot of new code. It does mean that the underlying mathematics are well-tested and can be relied upon to deliver high performance once the linux code has been tested out. I know both SGI and IBM has subjected them to qualified regression tests, but I don't know how extensively they have been used in real life servers.

Speed, primarily. You don't want to use encryption on a file system used for, say, a high performance database. regards Anders
There is a program that lets Windows look at ext2 filesystems, ext2dos, or something like that. I used to have it here, but it seems to be gone. If I could resurrect it, would it work with ext3? TNX, --doug

ext2fs - to be found at http://e2fsprogs.sourceforge.net/ext2.html I don't think it works for ext3 David On Tuesday 18 December 2001 23:13, you wrote:

I don't use windows, do I've never looked at that program, but if it can mount ext2 it should be able to mount ext3, only without journalling. //Anders
