Verified with e2fsprogs-1.42.9-4.el7 remove ext4 module and do mkfs, with e2fsprogs-1.42.9-4.el7 the mkfs is much faster and I can see ext4lazyinit kernel thread after mounting the partition [root@ibm-x3550m3-06 ~]# time mkfs -t ext4 /dev/mapper/testvg-lv50g mke2fs 1.42.9 (28-Dec-2013) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=0 blocks, Stripe width=0 blocks 3276800 inodes, 13107200 blocks 655360 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=2162163712 400 block groups 32768 blocks per group, 32768 fragments per group 8192 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424 Allocating group tables: done Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done real 0m1.661s user 0m0.146s sys 0m0.150s [root@ibm-x3550m3-06 ~]# mount /dev/mapper/testvg-lv50g /mnt/ext4 [root@ibm-x3550m3-06 ~]# ps -ef | grep lazy root 26481 2 0 18:15 ? 00:00:00 [ext4lazyinit] With e2fsprogs-1.42.9-3.el7 mkfs is slower and there's no ext4lazyinit kernel thread.
