how to use ext3 for boot partition?

**viet** · 03-21-2003, 03:59 AM

hi all,

Is there an option during the HD installation to set up an ext3 filesystem for the boot partition?

If I've already have an ext2 for my boot partition, how do I convert this into an ext3?

Thanks in advance for your help,
viet.

What you would do is as root:

tune2fs -j /dev/hdX where X is the proper partition descriptor

After you have created the journal with the command

tune2fs -j /dev/hdX

on the partition X, you have to change the filesystem entry for this
partition in the file

/etc/fstab

from

ext2 to ext3.

hi again,

i converted my ext2 to ext3 in the hope that I wouldn't have to run fsck after someone accidentally power off my computer (I heard journalled filesystems are "crash-friendly"). This hasn't realised for me. So ext3 is not THAT good?

cheers,
viet.

viet,

If you do a top is kjournald running? I had one system that I thought was running ext3 but actually it was running the ext3 in ext2 mode.

I still have fsck running on my ext3 systems also, probably a holdover to provide ext2 support on a system if necessary?? Although reliability is my main concern.

If anyone has installed KNOPPIX to the hdd on various file systems, I'd be interested in your experience. Specifically, what are the pros and cons of using ext2 vs. ext3 vs. reiser, etc.

TIA,
