Hi

I would be very grateful if someone would give me information about these FileSystems, how they work and other technical stuff and the difference between the two. Please assume no prior knowledge of these FileSystems.

There is a lot of information about this topic on this forum and google. Try there first and post back any specific questions you may have.

Well i had already tried Google as well as this forum search. The only thing that i got was that ext3 is journalling file system and its very easy to convert from ext2 to ext3. So i thought it would be better if any expert would tell me some info about these in his own words or if u know a good link, then post it here, Thanks.

Wikipedia is your friend.

I'm no expert but I like running off at the mouth.

Ext2 and ext3 are the most common file systems. Ext3 is a journalising type which makes it more robust but a little slower. If you have a hard shutdown or power loss the ext3 file system will probably survive. If it happens with ext2, you may fatally damage the operating system. I've been there, done that.



Reiserfs is VERY popular. Journalising and robust. Tests I have seen make it quicker than ext3. Reiserfs4 is newer and available in some distros, but is quirky.

Xfs and Jfs are other journalising file systems. I'm trying jfs right now and it seems very reliable. Some say jfs is slow but I thought otherwise. I know nothing about xfs except that it is more for server applications and big files.

Thanks for the help. I found some good sites
