to ext4 or not...

Rate this Message:
Hi Guys,
I just upgraded my desktop to fedora 11. The way I set up my system is with my home directory in a separate partition so that if I want to do an upgrade by reinstalling fedora, I can then reformat / and /boot leaving /home directory is untouched. But now there is ext4. So, should I leave /home as an ext3 file system? Or should I go through the trouble of backing up /home, reformatting to ext4 and restoring? Currently / is now ext4. Thanks. Steve. _______________________________________________ Discuss mailing list Discuss@... http://lists.blu.org/mailman/listinfo/discuss |

I would vote for a resounding "No". If you'll remember, I posted a few weeks ago how my wife's mail file was getting clobbered and corrupted after rebuilding my server on Ubuntu Jaunty and using ext4 for my root partition. Moving /var/mail to an ext3 partition fixed the problem completely, and that's all I changed. Other than setting up a process to back it up every two hours ;) I'm really stuck now, though, because there's no way to get my root partition back to ext3. Since it's /, it's got /dev and /proc and other things you can't just tar up. So I've symlinked some critical things like /var/mail to other filesystems. _______________________________________________ Discuss mailing list Discuss@... http://lists.blu.org/mailman/listinfo/discuss |

Not all ext4's are created equal. Red Hat has ext4 developers on staff who did a bunch of work to shore it up for Fedora 11. Kernel 2.6.29.4 and later have several key fixes that may not be in Ubuntu's 2.6.28. --jarod _______________________________________________ Discuss mailing list Discuss@... http://lists.blu.org/mailman/listinfo/discuss |

I haven't used it in several years, but http://www.mondorescue.org/ is perfect for putting your / on a new filesystem/RAID/LVM configuration. It'll build you a bootable cd/dvd that will restore your system in a configurable way, using the kernel/tools from your system that made the cds. (and it takes all the /dev and /proc stuff into account). Matt _______________________________________________ Discuss mailing list Discuss@... http://lists.blu.org/mailman/listinfo/discuss |

This removes /dev, /proc, etc. from relevance, and then you can tar up the root FS.
