It seems so. The disk is mounted without i/o being counted in /sys/block/sda/sda2/stat . If only half of the 733702 write ops of mkfs.ext4 were due to lazy_*=0, then they would keep with lazy_*=1 the disk busy for more than 6 hours at 16 ops per second. This matches my initial observation that it lasted for at least one hour. But in the end i can only say for sure that the drive LED behaves like before i mounted the lazily created ext4 in its encrypted partition. I had ext4 before. So my suspicions were rather directed towards the encryption, which is new for me. Now the whole story matches lazy ext4 creation, regardless of encryption. Have a nice day :) Thomas
