Public bug reported: Binary package hint: hal
I have an external USB harddrive with two NTFS partitions, one of which is LUKS encrypted. When I insert the HD hal recognizes both partitions and mounts them correctly. When I try to unmount the LUKS partition I get the following message in a popup error: Error tearing down /dev/sdb2 - fs still mounted?. The partition is unmounted but the DM device in /dev/mapper/ stays active. From the daemon.log I see: Jan 6 22:35:51 galar3 ntfs-3g[29282]: Version 2010.8.8 external FUSE 28 Jan 6 22:35:51 galar3 ntfs-3g[29282]: Mounted /dev/dm-2 (Read-Write, label "LarryWD500", NTFS 3.1) Jan 6 22:35:51 galar3 ntfs-3g[29282]: Cmdline options: rw,nosuid,nodev,uhelper=hal,uid=1000,umask=0077 Jan 6 22:35:51 galar3 ntfs-3g[29282]: Mount options: rw,nosuid,nodev,uhelper=hal,allow_other,nonempty,relatime,fsname=/dev/dm-2,blkdev,blksize=4096,default_permissions Jan 6 22:35:51 galar3 ntfs-3g[29282]: Global ownership and permissions enforced, configuration type 1 Jan 6 22:36:19 galar3 ntfs-3g[29282]: Unmounting /dev/dm-2 (LarryWD500) Jan 6 22:36:19 galar3 hald: unmounted /dev/dm-2 from '/media/LarryWD500' on behalf of uid 1000 But: $ sudo cryptsetup status luks_crypto_3873f57c-7755-4c39-aaf1-1f16e780f305 /dev/mapper/luks_crypto_3873f57c-7755-4c39-aaf1-1f16e780f305 is active: cipher: serpent-cbc-essiv:sha256 keysize: 256 bits device: /dev/sdb2 offset: 2056 sectors size: 956765084 sectors mode: read/write I then have to remove the mapping manually with: $ sudo cryptsetup luksClose luks_crypto_3873f57c-7755-4c39-aaf1-1f16e780f305 which completes its task without error, removing the mapping. If I don't remove the mapping manually and disconnect the HD, the next time I plug it, the LUKS partition is not automounted (the unencrypted partition is mounted alright but now as /dev/sdc1, whereas before it was /dev/sdb1). I followed the instructions from https://wiki.ubuntu.com/DebuggingRemovableDevices and produced a hal.log and udev.log which I am attaching to this bug report. I don't know if this problem has to do with the fact that the Harddrive has 2 partitions, one encrypted and one unencrypted, but at the moment I don't have any other HD with just one partition in order to perform more tests. I'm using Xubuntu, i.e., with Xfce and Thunar as the file manager. I don't know if this problems arises on Gnome or KDE.
