Hi all, I find that "kvm-xfstests -c ext4/1k ext4/049" is failed on current dev branch because of mkfs.ext4 failure. I can simply reproduce the failure by: # kvm-xfstests shell # /sbin/mkfs.ext4 -F -b 4096 -g 8192 -N 1024 -I 4096 /dev/vdc mke2fs 1.47.0 (5-Feb-2023) Discarding device blocks: done Creating filesystem with 1310720 4k blocks and 1280 inodes Filesystem UUID: a202296a-c5dd-495c-8aee-4bc92983083a Superblock backups stored on blocks: 8192, 24576, 40960, 57344, 73728, 204800, 221184, 401408, 663552, 1024000 Allocating group tables: done Writing inode tables: done Creating journal (16384 blocks): done *mkfs.ext4: Inode checksum does not match inode while creating orphan file* I also try this on my host machine with old version mke2fs. The orphan_file feature is not set in old version /etc/mke2fs.conf and the mkfs.ext4 works fine. After orphan_file added to /etc/mke2fs.conf, mkfs.ext4 failed as following: # mkfs.ext4 -F -b 4096 -g 8192 -N 1024 -I 4096 /dev/sda1 mke2fs 1.45.6 (20-Mar-2020) /dev/sda1 contains a ext4 file system created on Tue Jun 27 03:49:19 2023 Invalid filesystem option set: has_journal,extent,huge_file, flex_bg,metadata_csum,64bit,dir_nlink,extra_isize,orphan_file It's likely orphan_file is not supported by old version. After install new version mke2fs on my host machine. The checksum failure appears again: mkfs.ext4 -F -b 4096 -g 8192 -N 1024 -I 4096 /dev/sda1 mke2fs 1.47.0 (5-Feb-2023) /dev/sda1 contains a ext4 file system created on Tue Jun 27 03:49:19 2023 Creating filesystem with 1310720 4k blocks and 1280 inodes Filesystem UUID: 6ea06e27-5d56-4389-afaf-a99055fa85fd Superblock backups stored on blocks: 8192, 24576, 40960, 57344, 73728, 204800, 221184, 401408, 663552, 1024000 Can anyone help with this? -- Best wishes Kemeng Shi
