Large inodes
The current version of Ext2 IFS only mounts volumes with an inode size of 128 like old Linux kernels have.
Some very new Linux distributions create an Ext3 file systems with inodes of 256 bytes. Ext2 IFS 1.11 is not able to access them.
Currently there is only one workaround: Please back up the files and create the Ext3 file system again. Give the mkfs.ext3 tool the -I 128 switch. Finally, restore all files with the backup.
