This conversion is now done via a ioctl. This is the suggested method for defragmenting an ext3 inode (convert to ext4 and then defrag). b) small inode to large inode conversion is done via tune2fs -I < new_inode_size> I have patches for this ready. Will be sending them in a day or two. So the ext4migrate command may not be really needed. -aneesh
