Is it the same ext4 image for UML and VM? same image size? same mkfs version? What inode size do you have in UML setup? e.g.: dumpe2fs -h /dev/sda3|grep Inode.size dumpe2fs 1.42.13 (17-May-2015) Inode size: 256 have extra_isize feature? (not sure if that matters) dumpe2fs -h /dev/sda3|grep isize dumpe2fs 1.42.13 (17-May-2015) Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize Required extra isize: 28 Desired extra isize: 28
