on the wiki of my distro, I am seeing that warning
"Caveat emptor: the current version of e4rat (0.2.0) will severely damage any partition that has been converted to ext4. This is likely because existing files are not converted to use extents, and e4rat has no built-in mechanism to detect this condition. Before using e4rat you should backup the affected partitions, reformat them as ext4 and then restore the backups. Given the current status and the nature of the program, it's a smart move to backup the system before attempting reallocation anyway"
That worries me because I think I never completly rewritten that partition I upgraded from ext3.
So is the problem still there in 0.2.2 ?
If I run chattr +e on every file and directory on that partition, is it enough to prevent any problem ? I am wondering if chattr +e rewrites the file with extent or just change the attribute.
2. Is it working for my root partition with ext4 only or also /var and /home that I also have in ext4 but inside a crypted lvm ?
I can't access http://sourceforge.net/apps/mediawiki/e4rat
sourceforge is kind of having hard times serving page correctly. I got 500 error or or other error pages here
2. This issue was fixed in e4rat-0.2.3
3. The wiki is currently not in use. The old wiki was not up to date and filled with spam. I have currently no time for it.
