Hi, Diego Thanks for your efforts. About migrating from ext3 to ext4, you suggested the following: tune2fs -O extents,uninit_bg,flex_bg,dir_index /dev/yourfilesystem Tuning on flex_bg isn't supported yet. tune2fs doesn't really do the magic you want. It just sets the incompatible feature bit in super block and nothing else. An e2fsck after that won't modify the ondisk format either. e2fsck doesn't check log_groups_per_flex right now(might be a bug if superblock corrupts?). So even if you turn on flex_bg, fs doesn't benefit from flex_bg feature.
