Hi There seems to be a bug in ext4 - when I create very large directory, ext4 fails with -ENOSPC despite the fact that there is plenty of free space and free inodes on the filesystem. How to reproduce: download the program dir-test: http://people.redhat.com/~mpatocka/benchmarks/dir-test.c # modprobe brd rd_size=67108864 # mkfs.ext4 /dev/ram0 # mount -t ext4 /dev/ram0 /mnt/test # dir-test /mnt/test/ 8000000 8000000 deleting: 7999000 2540000 file 2515327 can't be created: No space left on device # df /mnt/test /dev/ram0 65531436 633752 61525860 2% /mnt/test # df -i /mnt/test /dev/ram0 4194304 1881547 2312757 45% /mnt/test (I tried to increase journal size, but it has no effect on this bug) Mikulas
