For an embedded system I create a filesystem with mkfs.ext3 on a desktop computer. Currently I'm evaluating newer distros for the desktop while the embedded stays the same. When checking the filsystem created with the new distro on the embedded device with fsck.ext3 I get the error "Filesystem has unsupported feature(s)" or "fsck failed (status 0x8)".
How can I find out which features are causing the problem as the error message is not very helpful? Is there a chance to create a filesystem identically to the ones created earlier by using the right switches of mkfs or does it add features I can't turn off?
