[03:52] <zinadork> Hello
[03:53] <zinadork> Has anyone else been having issues dismounting Truecrypt volumes
[03:53] <Bachstelze> zinadork: no, but I haven't used TC in a while
[03:53] <Bachstelze> what's the problem, exactly?
[03:56] <zinadork> device-mapper: remove ioctl failed: Device or resource busy Command failed
[03:56] <Bachstelze> well, tthat's self-explanatory
[03:57] <zinadork> it says that even if I try to dismount seconds after opening the partition
[03:57] <Bachstelze> you ave a process that is still using the drive
[03:57] <zinadork> I haven't opened any apps or files
[03:57] <Bachstelze> probably a shell, or a nautilus window
[03:57] <Bachstelze> fuser will tell you what it us
[03:57] <zinadork> I haven't opened them
[03:58] <zinadork> I saw the same issue in the truecrypt forums and it didn't look like it was solved
[03:59] <zinadork> is fuser and app or person?
[03:59] <Bachstelze> sudo fuser -m /mount/point
[04:00] <Bachstelze> will give you the PID of the process using it
[04:00] <Bachstelze> if it gives nothing, it's a bug in TC
[04:02] <zinadork> "specified filename /mount/point does not exist"
[04:03] <Bachstelze> replace that with the mount point of your TC volume ;)
[04:05] <zinadork> what do you do with the pid number?
[04:05] <Bachstelze> you do    ps aux | grep <pid>
[04:05] <Bachstelze> to find out what the process is
[04:09] <zinadork> the output was two 5digit numbers
[04:09] <Bachstelze> I get something like 
[04:10] <Bachstelze> /media/truecrypt1:   14472c
[04:10] <Bachstelze> so
[04:10] <Bachstelze> % ps aux | grep 14472
[04:10] <Bachstelze> firas    14472  0.2  0.0  41144  3588 pts/3    Ss+  05:09   0:00 zsh
[04:10] <Bachstelze> it's a zsh
[04:11] <zinadork> if I shutdown with it still mounted, do I risk damage?
[04:11] <zinadork> matt@HP-DV6:~$ sudo fuser -m /dev/sdb1
[04:12] <Bachstelze> in theory yes
[04:12] <zinadork> /dev/sdb1:           12374 12418
[04:12] <zinadork> matt@HP-DV6:~$ ps aux | grep 12374 12418
[04:12] <zinadork> grep: 12418: No such file or directory
[04:12] <zinadork> matt@HP-DV6:~$ ps aux | grep 12374
[04:12] <zinadork> root     12374  0.2  0.0 172676  2204 ?        Ssl  22:55   0:02 /usr/bin/truecrypt --core-service
[04:12] <Bachstelze> only one at a time
[04:12] <zinadork> matt     12625  0.0  0.0   8936   852 pts/0    S+   23:09   0:00 grep --color=auto 12374

[04:12] <Bachstelze> ok, that's a whole disk
[04:13] <zinadork> yes
[04:13] <zinadork> usb hdd
[04:14] <zinadork> it dismounts fine in windows
[04:14] <Bachstelze> let me try on a usb key
[04:15] <zinadork> thanks
[04:15] <zinadork> Very Helpful!
[04:22] <zinadork> You still here?
[04:22] <Bachstelze> ys
[04:22] <Bachstelze> it's formatting
[04:29] <zinadork> http://dl.dropbox.com/u/10464960/Screenshot-TrueCrypt.png
[04:29] <Bachstelze> well, it's not mounted
[04:29] <zinadork> i have access to the files
[04:30] <Bachstelze> that's probably a bug in TC then
[04:30] <zinadork> does it matter that it was encrypted using windows app?
[04:30] <Bachstelze> it shouldn't
[04:32] <zinadork> should I move the files to another disk and re-encrypt the directory in linux
[04:33] <Bachstelze> maybe it's the NTFS that's causing problemw
[04:33] <Bachstelze> with FAT I only see one process
[04:33] <zinadork> u'd use fat?
[04:33] <Bachstelze> (truecrypt --core-service)
[04:33] <Bachstelze> it didn't give me the option to use NTFS
[04:34] <Bachstelze> drive is too small probably
[04:34] <zinadork> this is a 320gig hdd
[04:34] <Bachstelze> yeah
[04:34] <Bachstelze> is it the first time you try to mount it on linux?
[04:34] <zinadork> no, but it has never dismounted properly
[04:34] <zinadork> newly encryped disk
[04:36] <zinadork> rather not use windows with disk.  I separate work and home by OS
[04:36] <Bachstelze> I wonder why the mount process is still active
[04:36] <Bachstelze> it shouldn't be
[04:36] <Bachstelze> that's probably the problem
[04:36] <zinadork> tc forums weren't helpful
[04:36] <zinadork> lots of people with same issue 
[04:37] <Bachstelze> probably a bug in TC then
[04:37] <zinadork> tc for linux, works in windows
[04:37] <zinadork> we do get the short end
[04:37] <Bachstelze> yes
[04:38] <Bachstelze> hmm
[04:38] <Bachstelze> what does the command "mount" give you?
[04:38] <Bachstelze> you should have one or two lines with "truecrypt"
[04:39] <Bachstelze> probably one
[04:39] <zinadork> http://dl.dropbox.com/u/10464960/Screenshot-matt%40HP-DV6%3A%20%7E.png
[04:40] <Bachstelze> ok
[04:40] <Bachstelze> yeah, it's probably the NTFS that's confusing it
[04:41] <zinadork> any good apps for ext4 support in windows?
[04:41] <Bachstelze> do you have an "Eject" icon in front of your drive in Nautilus?
[04:41] <zinadork> yes
[04:41] <zinadork> doesnt work
[04:41] <Bachstelze> not that I know of
[04:41] <Bachstelze> even ext2/3 supposrt is flakey
[04:42] <Bachstelze> hmm
[04:42] <Bachstelze> try
[04:42] <Bachstelze> sudo umount /dev/dm-0
[04:43] <zinadork> umount: /dev/dm-0: not mounted
[04:44] <zinadork> I give up
[04:44] <zinadork> I'll try a fat fs next time
[04:44] <Bachstelze> yeah
[04:44] <zinadork> thank you for helping me
[04:44] <Bachstelze> probably a bug in TC, the kernel parttion table is out of sync
[04:44] <Bachstelze> no prob
[04:45] <zinadork> good night
