When mounting ext3, states "1.0% Non-Contiguous"

Hi,
Whenever I mount my ext3 partition, and it checks the filesystem it states,

1.0% non-contiguous

It asked me to do maintenance the first time this error came up, but I could not fix it, and ended up rebooting. How do I do the maintenance?

fsck

(don't play with it, if you don't know what you are doing)


The impossible missions are the only ones which succeed.

Use cfdisk.  This man page should help you.   http://unixhelp.ed.ac.uk/CGI/man-cgi?fsck+8

Ext3 is a stable filesystem, you can consider to configure / partition in /etc/fstab with "0 0" instead of "0 1".
Example:
/dev/discs/disc0/part3 / ext3 defaults 0 0

Myself, for last three years using "0 0" in countries with power failure without having any problem..... except losing my work when electricity goes off before saving the document.  wink

What does it really mean that the fs is x% non-contiguous??

On my last check fsck reported 7.5% Non-Contiguous on one of my partitions. I don't know if i should worry or not and how should i fix the fs "problem".

non-contiguous means fragmentation. If you want to defragment your partition, there might be some tool.  Usually, in Linux you don't need to defragment  since the filesystems are more performant thant the windows one.  I wouldn't worry unless the % gets  big.
