With Ext3 you can grow the filesystem offline and with a kernel patch you can grow online, you can not shrink.This is not true. Using resize2fs you can grow and shrink the filesystem,
but only offline. I'm not sure about the kernel-patch, but I'm certainly
sure you can shrink at least offline. And using e2fsadm in conjunction
For the online grow kernel patch there are informations at:
http://ext2resize.sourceforge.net/
or
http://sourceforge.net/projects/ext2resize/
For the merge of the patch in the 2.6 kernel there are informations at:
http://www.kernelnewbies.org/status/latest.html or http://kerneltrap.org/node/view/716
but I can not find the patch.
Best regards.with lvm is even more comfortable ;)) Although it had some issues with ext3, as sometimes a filesystem is reported unchecked even if you have run an e2fsck -f just right before. But adding a -f to resize2fs has always worked for me without any trouble at all.
I chose ext3 2 1/2 years ago, when doing kernel development for my diploma thesis, and an occassional ooops or other crash happened almost regularily. And waiting for the filesystem check annoyed me after the 3rd time ;)
The argument for ext3 at this moment was, that you can easily convert an ext2 filesystem to an ext3 filesystem using tune2fs -j (to add the journal), and even mount the ext3 filesystem as ext2, making it available even if you have no support for ext3 in your kernel (2 1/2 years ago quite important!)
Ext3 has never failed me in this time, I had no failure of filesystem and the performance was also good, at least for my needs :)
CU all,
