** Description changed: nilfs-tools 2.1.5-1 on a fresh install ubuntu 13.10 x86_64 The filesystem mounts and seems to be working correctly (also lscp, mkcp and others seem to work as expected), but when trying to umount the device (be it a real partition, loop device or luks device) the result is always this one: # umount /mnt/nilfs/ umount.nilfs2: /dev/loop0: device is busy umount.nilfs2: /dev/loop0: device is busy # umount /dev/loop0 umount.nilfs2: /dev/loop0: device is busy umount.nilfs2: /dev/loop0: device is busy # lsof /mnt/nilfs/ Output information may be incomplete. COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME nilfs_cle 2777 root 5r DIR 7,0 4096 2 /mnt/nilfs # ps aux | grep 2777 root 2777 0.0 0.0 14824 904 ? Ss 19:59 0:00 /sbin/nilfs_cleanerd -n /dev/loop0 /mnt/nilfs # kill -9 2777 # umount /mnt/nilfs/ <-- Works So, it seems like nilfs_cleanered prevents the device from being umounted at all times. This bug is reproducible 100% of the times for me. Killing the deamon seems to be the only way to umount a nilfs2 mounted partition. --EDIT-- This is also reproducible when booting from the live CD image of ubuntu 13.10_64 (I booted from liveCD image, added community repository and "apt-get update && apt-get install nilfs-tools") + + --EDIT2-- + Version 2.1.0-1 of nilfs-tools on Ubuntu 12.04.3 LTS was unaffected from this bug, just tested it.
