ext2-3

Nobody's Hero — Tue, 29 Jul 2003 10:46:23 GMT

When I build a linux RH8 system, should my / filesystem be ext2 or 3? And what is the difference? Is it like HFS and vxfs in the HPUX world?

Hi

ext3 is equivalent to ext2 with journalization. You can make / in ext3.

Robert,

"ext3" is a Journaled/Logged file system. I won't swear to it, but I'm pretty sure logging is turned on by default.

ext3 is like ext2, but it is more tolerant to power failures and system crashes. Now ext3 is enough stable so a lot of linux distributions (like redhat) use it as default filesystem.

I think that the new 'reiser file system' worth a look, too. I'm using it with RH9, and it has better performances than ext3. Now I don't remember where you can find docs about reiserfs :-) try with google or in www.tldp.org

ext3 is as noted earlier the default fs in many distributions.

It is a journaling filesystem, like HP-UX(Veritas) vxfs/JFS filesystems.

It is quite tolerant of power failures, I've tested the functionality frequently.

ext2 is Linux extended filesystem 2

ext3 is also and extended file system... but is what is known as a journeling file system. Another journeling file system is reiser (reiserfs). A journeling file system is more resiliant than a non-journeling system... as it says..it journels... or writes data in a way to allow for easier recovery

Ext3 is not only safe... but recommended to user for /

Hello!

ext3 is just the same filesystem as the ext2
the only difrence is the jurnal that ext3
have.
That's mean that if your filesystem should made
a recovery so if you use ext3 then it will be
much faster than ext2.

In any time you can migrate from ext2 to ext3
and back.

Ofcource better to use ext3 for you.
