It looks like the problem is that your kernel config doesn't enable CONFIG_QFMT_V2. As a result, the quota feature is not supported in the kernel under test. From ext4/033.full file: mount: /media/scratch: wrong fs type, bad option, bad superblock on /dev/loop5, missing codepage or helper program, or other error. dmesg(1) may have more information after failed mount system call. mount -o acl,user_xattr -o dioread_nolock,nodelalloc /dev/loop5 /media/scratch failed And from the ext4/034.dmesg file: [ 297.969763] EXT4-fs (loop5): The kernel was not built with CONFIG_QUOTA and CONFIG_QFMT_V2 Cheers, - Ted
