ext3 vs. ext2 1

[Nostradamus]

What are the major differencies between these to filesystems?
I've never worked with ext3 before. Didn't find any decent information about it either. Believe I read somwhere that it had some journaling capabilities? /Sören

Hi,

Have a look at the redhat whitepaper -->

http://www.redhat.com/support/wpapers/redhat/ext3/index.html

.

In essence, ext3 is ext2 with journalling. There is nothing fundamentally different from the ext2 filesystem and you can even mount an ext3 filesystem as ext2 if you like. The main advantage is data protection insofar as it has the journalling functionality - so a power failure or whatever should not cause loss of data, at least in theory.

The main other advantage is because of the higher integrity of ext3, the system does not do a forced fsck after every 20 reboots as it does with ext2. That can be a major plus factor sometimes....

Regards

Sounds like there's only advantages...
backward compatible, easy to upgrade ext2 to ext3, faster, no fsck (YES!) and journaling (OH YEAH!).

I'll go with ext3 (of course).

Thanks for the link ifincham. It was just was I was looking for. /Sören
