slow ext4 fsck
I converted my 80GB partition from ext3 to ext4 with the instructions in the wiki.
It doesn't fsck very fast, about the same speed it did when it was ext3.
It goes fast in some spots, and apears to stop for a while in other spots.
any suggestions?

Re: slow ext4 fsck
For the speed advantages to be realized, you have format the partition in question to ext4, then copy the files back... that is my understanding. Otherwise, 'converted' files are still extent-less.

Isn't there some defrag tool that fixes that?
And this is my / partition. Could I reformat without reinstalling?

Re: slow ext4 fsck
Well... if you could boot from a live CD, rsync the / to another partition, format it and rsync it back, I don't see why this wouldn't work with the / partition... I did this to my /home last night and it is now ext4. You might wanna wait for someone else to answer your post who is more knowledgeable and I am about this.

This is how I basically migrated my / partition .
1) Use a recent Parted Magic live cd .
2) Mount your Arch partition .
3) Mount a storage partition with sufficient free space .
4) Backup your Arch partition (the classic way using 'tar' or with rsync) and save the backup in your storage partition .
5) Unmount your Arch partition and reformat it to EXT4 (I used mkfs.ext4 for this) .
6) Remount your Arch partition .
7) Restore the backup to your Arch partition & make sure the filesystem hierarchy is right .
8) Edit '/boot/grub/menu.lst' and '/etc/fstab' (Remember to use the new UUID) .
9) Fix grub as explained in the wiki here .
10) Done .

Re: slow ext4 fsck
Uhm.. I just reinstalled Arch linux few days ago.
At the installation I formattet the / partition and chose ext4.
I just got my first fsck after 50 mounts, and it took several minutes. My / partition is only 10gb and my entire harddisk is 80 gb.
