In the past I have done the same test for ext3 and it was created ~10M files in one firectory at working filesystem (/home) and it was no issues reached. On ext4 i found inodes max size is limited as you wrote: [root@cgmachine sandbox]# df -i /e4 Файловая система Инодов Испол Своб Исп % смонтирована на (file system/inodes/used/free/used%/mounted on) /dev/sda4 1,8M 1,8M 0 100% /e4 [root@cgmachine sandbox]# Why inodes count limit is so small by default? Is it depends on partition size?
