Cannot mount Truecrypt volume (device-mapper error)

I have a 1TB external USB disk (externally powered) and I have created 3 partitions on it:
Disk /dev/sdb: 1000.2 GB, 1000202043392 bytes
255 heads, 63 sectors/track, 121600 cylinders, total 1953519616 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 2048 696322047 348160000 7 HPFS/NTFS

/dev/sdb3 1744824320 1953517567 104346624 7 HPFS/NTFS
The last partition, /dev/sdb3, has been formatted with Truecrypt 7.0a and I'd like to mount it, but truecrypt reports the following error:
device-mapper: reload ioctl failed: No such file or directory
Command failed
I am getting the same error with my custom kernel and with stock Arch Linux kernel; what can it be? Can somebody please help me to narrow down this issue?
Thanks

Ehm..I am trying to mount the device (/dev/sdb3), not the mapper! Although I can see that with file-based truecrypt container the mapper gets mounted. Shan't truecrypt create the mapper and mount that for me in case I select a device?
This is the information of the two mappings created (2_0 and 2_1 since I had already mounted a file-based container):

None of them gets mounted after I get the mentioned error; maybe truecrypt is expecting a dm feature which I have not enabled in my kernel?

Backup Controller cannot mount XSAN Volume

Hi Guys,
I've really have a big problem regarding the XSAN that I've just setup: There are 3 Xserves connected to the SAN - one for the main controller, one for backup and another one for fileserver. After a fresh install of the Leopard Server 10.5.6 on all servers and fresh install of Xsan 2.0 updated to 2.1.1, I tried creating an SAN from the main controller, I added first the main and backup controllers, authenticated them properly and was successful adding them to the SAN. After this, I created the volume and it mounted properly on the main controller. What I don't understand is that whenever I try to mount the volume to the backup controller, it is saying unable to mount and even I tried forcing it to mount in terminal using the command xsanctl mount VOLNAME, its giving me an error saying
"unable to mount volume, Cannot mount XSAN volume error code: 5"
What is that error message? When I tried typing cvadmin to the main controller, it only gave me this message:
Main Controller:
File System Services (* indicates service is in control of FS)
1>*XSAN[0] located on 10.0.0.101:49930 (pid 317)
Select FSM "XSAN"
When I type the same cvadmin to the backup controller, it gave me this message:
Backup Controller:
File System Service (* indicates service is in control of FS)
1> XSAN[1] located on 10.0.0.102:50384 (pid 331)
No FSSs are active
Select FSM "none"
What is happening? both servers are having a DNS name. Before I created the SAN, from the authenticate window, the server name is just the IP address of the Ethernet 0 (first ethernet port). Now whenever I fire up Xsan Admin, both controllers are now offline and if you authenticate them, the server name info suddenly changed from IP address to a DNS Name (e.g. from 194.170.34.12, changed to hct-mdc.ad.hct.ac.ae) which even if I type my admin username and password cannot authenticate saying "server not found in network"
I really don't know now what to do and they need to fix the issue asap.
I would really appreciate your help guys!
Thanks.

Hi,
I am accessing this WS via ARD, so public LAN is definitely there. I have not connected the "Xsan" network (but it should be no problems communicating the Xsan traffic over this single LAN connection).
With the firewall, the situation is more strange. When I try to open the Firewall settings on Sharing, there is a dialog "Other firewall software is running on this computer." I googled this and it seems that this was a common problem on 10.3. They suggest to delete com.apple.sharing.firewall.plist file but it is not there on 10.4.
"sudo ipfw list" shows this:
00001 allow udp from any 626 to any dst-port 626
65535 allow ip from any to any
Any ideas on how to make Firewall behave as expected? I will try to reinstall if I don't receive a reply.
Thanks.

LUKS/dmcrypt device-mapper error

Hi,
Ok this is a strange one because I have several encrypted volumes already in use working fine, yet im having problems creating a new LUKS container with cryptsetup on a new USB hard drive.
Just using standard AES in XTS mode, and all the required kernel modules (dmcrypt/aes) are loaded.
[root@tcore media]# cryptsetup -c aes-xts-plain -y -s 512 luksFormat /dev/sdf1
WARNING!
========
This will overwrite data on /dev/sdf1 irrevocably.
Are you sure? (Type uppercase yes): YES
Enter LUKS passphrase:

Check that kernel supports aes-xts-plain cipher (check syslog for more info).
This is /dev/sdf:

Any ideas? As my kernel clearly does support the cipher. Possibly a USB issue as all my other volumes are on internal SATA drives?
EDIT: on some attempts the error varies and also shows: device-mapper: remove ioctl failed: Device or resource busy

hello all
I have been asked to look into a problem server with the following details
OS: sunOS 5.8
Oracle: 10.2.0.1
sys user password is not available !
backgrround processes for the instance(sid=test) are running
only schema credentials available and with that user is able to connect.
verified all oraenv parameters(ORACLE_SID is same as the running instance(test)).
only one instance is configured in this server(verified all tnsnames.ora, data files etc).oratab is empty
the issues are,
when I tried to connect to the server using "oracle" user using conn / as sysdba
1. Tried to shutdown using , shutdown immediate
ORA-01507:database not mounted
ORACLE instance shut down
still able to see the background processes and user is able to connect
2. Tried startup command,
In the nomount state I can see more than one PMON process with the same sid
when tried to mount/open
ran into the error,
ORA-01102: cannot mount database in EXCLUSIVE mode
Eventhough the background processes for the "test" instance are running I am not able to shutdown the instance using "oracle" user
please help
newbie

hi
i renamed lk* file but the issue still remains,
with the oracle user
1./ as sysdba
2. shutdown immediate
this leads to
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist

there is only one oracle home and the oraenv details are set with the correct values
verified the alert log(ora home details are matching with the env details), details of the oracle processes which are active are in the alert log along with the startup failures(mount errors) at the tail end
oracle sysdba is not able to identify the already running instance?
please help

[SOLVED] pam_mount will not mount truecrypt volume on login.

Hello.
I did system upgrade yesterday and encountered some problems with mounting my Truecrypt volume with pam_mount. I use pam_mount to mount my encrypted /home partionion at login. After first reboot and loging in I was dropped to / directory, with my /home partition clearly not mounted. I acknowledged the message from udev in pacman, that in some circumstances adding 'loop' to MODULES array in /etc/mkintcpio.conf is required and for a moment I thought it was it, but I tried this and it didn't help. Suprisingly, after another reboot I was placed im my home directory afer login, but it appears to be empty - I can see only dotfiles of few programs I used after the upgrade:
$ls -A ~/
.bash_history .links .qingy .viminfo .wicd
but my /home partition is obviously still not mounted. My relevant config files:
/etc/security/pam_mount.conf.xml

[EDIT] OK, I've looked into it a little more and I realised that I should try loging in without qingy. I tried on agetty console and it worked as before. It looks like qingy upgrade changed my /etc/pam.d/qingy file into default one. The one above is and obviously unsuitable for use with pam_mount and I failed to see that at first. It should look similar to the example file for slim in the wiki article on pam_mount:

Sorry for the trouble, maybe at least it will help someone.

Cannot Mount Boot Volume

My iBook G4 stopped booting properly this morning. I was installing the Adobe After Effects CS3 trial when the screensaver came on after a while, but when I moved the mouse to deactivate it, the authentication dialog did not appear as usual, so I force shut down the iBook. However, it subsequently failed to boot properly (i.e. does not boot past the grey/blue screen with the spinner). At the time of malfunction, I had an external hard disk and a disk image mounted.
I booted from the Mac OS X Install CD, but Disk Utility was unable to mount my boot volume (though it could show the volume information and verify the disk) to fix permissions. I also tried booting in single user mode; upon typing the command "mount -uw /", I got the following error messages:
jnl: replay_journal: from: 301568 to: 7035904 (joffset 0x41e000)
disk0s9: I/O error.
jnl: updatefsblock: failed to update block 6026 (ret 5)
jnl: journal_open: Error replaying the journal!
Aug 27 17:54:11 launchd: chown ("/var/launchd/0"): Read-only file system
Aug 27 17:54:11 launchd: chown ("/var/launchd/0"): Read-only file system
mount_hfs: Invalid argument
Hence, I suspect the problem may have something to do with disk journaling, which is enabled on my boot volume. I am quite sure that the volume itself is working fine, since I was able to access my data when it mounted as read-only in single user mode.
Does anyone here know of a possible solution to my problem? I would prefer to avoid a clean install of OS X. I do, however, have a recent back-up (created by Carbon Copy Cloner) on hand. Thanks in advance!
Regards,
Liza

Does anyone know of a possible solution? This tip looked promising, but my iBook G4 only starts up in Mac OS X (i.e. cannot boot OS 9). Neither can an OS 9 computer read the iBook's hard disk, since I did not select the option to install Mac OS 9 Disk Drivers when formatting it. I have also tried DiskWarrior, but to no avail.
Since I have a back-up of the disk on hand, I want to reformat the disk, but I cannot accomplish this using Disk Utility when I boot from the Mac OS X Install CD. Do I need any special software?
Thanks.

Cannot mount winpe boot.wim with error:3

Hi there
thats what i´ve done:
first i installed the adk (build 10057) after i´ve removed the old one completely.
then i´ve used copype to create new files (copype amd64 c:\123)
after this i´ve used this command:
Dism /Mount-Image /ImageFile:c:\123\media\sources\boot.wim /mountdir:c:\123\mount /index:1 /loglevel:4
and i get the error message
Error:3
The system cannot find the path specified.
Here is the Log: http://pastebin.com/djPfKXdN
Whats wrong? Can someone else confirm this?
p.s. i get the same error if i use an different/older wim-file...

Hi,
Currently, we only have latest preview build to 10049 via Windows Update. For the ADK, please make sure to use ADK for Windows Technical Preview
https://msdn.microsoft.com/en-us/library/windows/hardware/dn938390(v=vs.85).aspx
I tested in my mahcine, and the operation completes successfully
The logs shows that something is missing in the dism store, I recommend you uninstall the Deployment tools which contains DISM in ADK, then reinstall the tool as a test.

I cannot mount my hard drive volume!

Began a standard install of OS 9.2.2 and then my hard drive icon disappeared from the desktop. I opened drive setup from the utilities folder of the 9.2.2 cd and I cannot mount the volume no matter what. I can only start up from the cd holding down the c key and that's as far as I can go. Is this it for this powerbook? Trash time? HELP!

monkybiz,
If initialization failed, there is a problem with the HD. However, there is a process that may correct the problem or it will definitively tell you the HD is bad. HDs can fail at any time so it just may be coincidence the problem arose when trying to install software.
Since initializing the HD failed, apparently the computer can now see the HD. Boot to your MacOS 9.x CD and open the folder that says Utilities and launch Drive Setup. Highlight your HD's name in the window, then move up to the menu bar. Under Functions, select Initialization Options, then check the box for 'zero all data'. Also select MacOS Extended Format when that window appears. When the process has completed (it will take awhile), select 'Test Disk' under Functions (it will also take a while). If zeroing fails or Test Disk fails, try again to zero and then run Test Disk.
If successful, install software; if the above fails, your HD is hosed. By the way, once Drive Setup has been launched, Drive Setup Help is available from the menu bar.

[SOLVED / Workaround] Hiding a TrueCrypt volume

I have a TrueCrypt file that contains my personal information. I mount it from the command line when I need it. How can I hide the mounted TrueCrypt volume from appearing in my file manager (PCManFM)?
I tried creating a udev rule in "/etc/udev/rules.d/99-hide-partitions.rules":
KERNEL=="dm-[0-9]*", ENV{UDISKS_IGNORE}:="1"
It had a small effect: the volume still appears in the file manager but it has a different name.
Here is the output from "udevadm monitor" when I mount the volume:
KERNEL[720.311712] add /devices/virtual/bdi/0:34 (bdi)
UDEV [720.329283] add /devices/virtual/bdi/0:34 (bdi)

UDEV [720.537028] add /devices/virtual/bdi/254:0 (bdi)
KERNEL[720.537390] add /devices/virtual/block/dm-0 (block)

UDEV [720.588484] change /devices/virtual/block/loop0 (block)
UDEV [720.612304] change /devices/virtual/block/dm-0 (block)
How can I hide the volume from my file manager? Should I use udev or another method?
Thank you!

Yes, as far as I know dm-0 is correct, you can use it like that in a udev rule.
Did you have a look at '/lib/udev/rules.d' , maybe you need to change "99" in 99-hide-partitions.rules, it needs to have a different number I guess, looking at the files in '/lib/udev/rules.d'.
I would call it 15-hide-partitions.rules, really I don't know if it works, but you could try
I can't check it for you as I don't have a dm device on this machine.
edit: Ah, so now I see what you mean, although I don't have a solution.
I checked with Truecrypt volume on USB disk, all other USB's are correctly ignored, also the USB disk with truecrypt vol. on it. When I mount it, it shows up in the list.
I tried to write a few rules for it, but they all fail, I use a little script to enable/disable it which is working fine for USB.
I guess you already issued a command like this to find out more about your device:
#udevadm info -a -p $(udevadm info -q path -n /dev/sd**)
Because it looks like when you issue the command, dm-0 is not appearing in the list, I only see this with "udevadm monitor" , so I try some more, I think however, we need some help
edit2: I have been playing around with udev, I just couldn't get it to work ,so I wrote a little script for it, maybe you can use it, with an alias in your zshrc
It's just a little mount/unmount script, check your major/minor number, and change the mountpoint to yours.
#!/bin/bash
if [ "$(mountpoint -d /media/truecrypt1)" = "254:0" ] ; then
sudo umount /media/truecrypt1
echo "Device /media/truecrypt1 is unmounted"
else
sudo mount /dev/dm-0 /media/truecrypt1
echo "Device /media/truecrypt1 is mounted"
fi
exit 0

Look likes , you setup standby on same machine , try init.ora parameter LOCK_NAME_SPACE. Also make sure you use standby control file for standby database.

Truecrypt-6.0a to 6.1 - error: "No entry for device-mapper found."

/proc/misc: No entry for device-mapper found
Is device-mapper driver missing from kernel?
Failure to communicate with kernel device-mapper driver.
Command failed
that's the full error I get when trying to mount my encrypted drive - I'm sure there is a simple fix for this but no one else seems to have the same issue, I compiled from the source but still got the same error.

Mounting truecrypt device on GPT WD Elements

I have successfully formatted /dev/sdb2 with truecrypt on my external USB WD Elements 1TB (formatted with GPT partition table), but I have never been able to mount it. I keep getting this error when attempting to mount (with the correct password):
device-mapper: reload ioctl failed: No such file or directory
Command failed
There is of course no problem when mounting a loopback file and not a real device file; I also suppose that all kernel modules are in place:
$ dmsetup version
Library version: 1.02.60 (2010-12-20)
Driver version: 4.19.1
$ dmsetup targets
crypt v1.10.0
striped v1.3.1
linear v1.1.0
error v1.0.1
I really have no clue about this problem! How can I debug it further and fix it?
Thanks in advance

Hello and welcome to the WD community.
In some cases Smart TVs do not see hard drives unless the drive is formatted in FAT32, However if the drive is visible on the TV, then make sure that the TV is able to play *.mkv files.

Cannot mount volume

Hi
I have a server connected to a MDC.
The MDC is running 10.4.8 server, XSan 1.4.1.
The MDC can mount the SAN correctly.
The client is running 10.4.8 server, XSan 1.4.1
The client cannot mount the SAN.
What I've tried:
Re-installing XSAN
Re-installing the 10.4.8 combo update
Re-installing the 2006-007 security update
Changing from Controller, medium to client and back.
mount -t ... /Volumes/SAN
Every time I get this in the syslog:
Dec 13 13:54:35 xsanclient kernel[0]: Could not mount filesystem SAN, cvfs error ' Timeout' (25)
any ideas

More from the log:
