Well, the blinking went on for at least an hour. > Create with: > mkfs.ext4 -E lazy_itable_init=0,lazy_journal_init=0 This lasts significantly longer than my first mkfs run. The drive makes ~ 1950 write operations per second. So i estimate that the job would have lasted hours with ~ 16 writes per second. In the end mkfs.ext4 caused 733702 write ops on the 3.6 TB partition. Ok. New UUID into fstab ... mount ... mkdir ... touch ... Yay ! The i/o is still lazy (no wonder with 32 GB RAM), but after about a minute i see no newly counted writes. Thanks a lot ! Have a nice day :) Thomas
