"none already mounted or /dev/pts busy" udev 050-2

Just did a clean install on a new hard drive. Using udev. Haven't made any changes from default, except added "devfs=nomount" to the grub boot line.
I get this error message during boot up:
"none already mounted or /dev/pts busy"
when I issue "mount" command, I do not see /dev/pts listed. If I try "mount /dev/pts" I get the same complaint "none already mounted or /dev/pts busy"
1. What is pts? Why would it be busy?
2. How do I solve this complaint?
Thank you,
John R
[edit] was directed to bugs.archlinux.org, a report exists there.

Is this line in your /etc/fstab?:
/dev/pts devpts defaults 0 0

On a system without LVM, a filesystem is created inside a partition. fdisk is used to list partitions on disks. Because the filesystems are inside the partitions, you can use the name of parition to mount it.
On a system with LVM, a filesystem is created inside a logical volume, not in a partition. The partitions (fdisk -l) are used as physical volumes (pvdisplay), which are added to a volume group (vgdisplay), in which a logical volume can be created (lvdisplay). In the logical volume a filesystem is created. Because of this, only the logical volumes can be used to mount the filesystem.
LVM adds an abstraction layer between filesystems and partitions. This is extremely handy because it's easy to add a disk (which is made physical volume) to a volume group which makes space available, which can be added to any logical volume in the volume group. When that's done, the filesystem in the logical volume can be enlarged with resize2fs, even online. Without LVM, it's not possible or very hard at best to do that.

[SOLVED] mount: /dev/sda3 is already mounted or /mnt busy

Hello all, I've spent several hours researching this to no avail. I'm trying to mount my partitions, first with my root partition (/dev/sda3) mounted at /mnt. It seems no matter what partition I try to mount it gives me the same error: mount: /dev/sda3 is already mounted or /mnt busy. I've tried the fuser command and killed all process associated with this device but new processes seem to pop up making it busy once more.
Hopefully somebody has some knowledge of what could be causing this one.
Thanks, and I hope to resurrect an Arch workstation once more!

Oh yeah this is Arch so I would use pacman. The community database along with core and extra does not exist... when i run pacman.

Mount fat32 on x86: already mounted or busy

hi. i suppose mounting fat32 on x86 is well-documented, but i'm having trouble, so i'd appreciate some help.
im dual booting with solaris 10 and xp. my partitions are as follows:
1st physical drive
[boot sector] 55 MB
[c:] label XP (NTFS)
solaris partitions...
2nd physical drive
[d:] label Data (FAT32) (about 17 GB)
i'd like to mount my FAT32 drive. according to man mount and man pcfs, i thought i'd do seomething like:
bash-3.00# mount -F pcfs /dev/dsk/c1t0d0p0:d /mnt/data
which yields:
mount: /dev/dsk/c1t0d0p0:d is already mounted or /mnt/data is busy
theres nothign in the /mnt/data folder. as far as i can tell, the drive isn't mounted. am i naming hte wrong device? im reading this "device-special:logical drive" stuff and i guess it's not making sense. i've included some more info below.
hopefully after this i can mount the drive in the vfstab, but if not i suppose ill be back.

thanks!!!

thanks martin
i think i was trying to mount a SCSI drive instead of IDE that I have... thanks for clearing that up. i was also frustrated with teh :c part, I think I forgot about the 1st partition part.
im under the impression that c0d0p1:c is my first physical drive, which is NTFS because of:
bash-3.00# mount -F pcfs /dev/dsk/c0d0p1 /mnt/data
mount: /dev/dsk/c0d1p1:c is not a DOS filesystem.
but then why would c0d1p1 also yield:
bash-3.00# mount -F pcfs /dev/dsk/c0d1p1 /mnt/data
mount: /dev/dsk/c0d0p1, c0d0p2 is not a DOS filesystem.
then again c0d0p0, c0d0p2, and c0d1p0 yields the same...
is there a way to list the devices present, or do i have to throw knives at the wind? does anyone understand the naming schema of cN and dN? man pcfs and man mount don't help a whole lot.
i dont see anything helpful in the vfstab

Cannot mount cgroup: already mounted or busy

I am unable to mount cgroups on a fresh boot of a recent installation, fully up-to-date.
# mkdir /cgroups
# mount -t cgroup none /cgroups
mount: none already exists of /cgroups busy
According to lxc-config, I have cgroups enabled, and `dmesg | grep -i cgroup` confirms that the relevant subsystems are initialized. I am not finding anything added to dmesg.log, kernel.log, everything.log, etc., by the mount command.
Any ideas?

X4100 mount command for second drive shows device already mounted

I have a new x4100 system and I created a new partition and ext3 filesystem on the second drive. When I try to use that partition I get the error:
mount: /dev/sdb1 already mounted
Since this is a new system, that partition has never been used and I can't see anywhere that the device is in use. I tried the same thing on other systems and I get the same error. Has anyone seen this problem and if so how was it resolved?
thanks

Already used Logical System in Business Service?!

Hi, well i am facing a JMS2IDoc-Scenario.
As sender i configured a Business Service (K15) with the CC_JMS. The receiver is a business system (HRT) with the CC_IDoc.
While i test the scenario i received following error:
"Unable to convert sender service to an ALE logical system"
Thats fine so far, therefore i checked the Adapter-Specific Identifiers and entered the Logical-System name. This is already in use at the business system (HRT) because of some CC for other Scenarios.
Now there is the problem that i can't use this logical system name at K15, no idea why.
Because of not having the technical details of the source-system (JMS) i choose to use business service. Is there another idea?! Party?!
br, Jens

Hi,
The issue is with the fact that this Logical System Name has been assigned to another Business System ( say Buss System X) .And you want to use this same Logical System Name for the sender JMS service( Buss System Y) as well , correct?
Solution is,
In the Receiver Agreement , Select Header Mapping and for the Sender Servicce, select the Correspodning Sender Service ( Sleect Buss System X )to which the Logical System Name is assigned.
Now in the runtime this will be used as the Sender Service from which the Logical System Needs to be taken.

IS Windows 7 already Mounted on BOot camp in OS x Mountain Lion

Hi GUys
i just wanted to ask that is the Windows 7 64 bit already mounted on BOOT CAMP in OS X mounation lion............... if it is do i need to buy a Disk for windows 7 Just in case

Of course you have to buy it. And then you have to install it. did you really think you'd get it for free?

Phone SD card mounts to /dev/sdh (not /dev/sdh1)

I got a new Android phone (<3) the Samsung i7500. Its internal and external SD cards mount to /dev/sdh and /dev/sdi respectively. I found out with dmesg:
scsi8 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 7
usb-storage: waiting for device to settle before scanning
scsi 8:0:0:0: Direct-Access Samsung SAMSUNG Android Mass PQ: 0 ANSI: 2
sd 8:0:0:0: Attached scsi generic sg8 type 0
scsi 8:0:0:1: Direct-Access Samsung SAMSUNG Android Mass PQ: 0 ANSI: 2
sd 8:0:0:1: Attached scsi generic sg9 type 0
sd 8:0:0:0: [sdh] Attached SCSI removable disk
sd 8:0:0:1: [sdi] Attached SCSI removable disk
usb-storage: device scan complete
And fdisk doesn't list them. And these are actual partitions, not disks. I mounted them, and they have the stuff I'm looking for. Why is it like this? One bad thing about this is that fdisk -l doesn't list them, and I have to use dmesg to look at where they pop up each time. That's rather unnecessary IMO.

I suppose that the filesystem could have been written to the raw device and not to a partition. This is fine as long as you don't need multiple filesystems on one device (i.e. multiple partitions).

Root.sh diskgroup already mounted in another lock name space

I have successfully installed oracle grid infrastructure 11.2.0.3 and have created an oracle database on an asm instance on top of it.
I installed the database as a RAC database on a single node db-test-mi-1, postponing the addition of a second node at a later time.
Now I have a second node db-test-mi-2, that I need to add to to the database.
I have successfully performed
cluvfy stage -pre nodeadd -n db-test-mi-2 -verbose
without any errors.
When I try to extend grid infrastructure to the new node, with
./addNode.sh "CLUSTER_NEW_NODES={db-test-mi-2}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={db-test-mi-2-vip}"
it works fine, but the script /oracle/app/11.2.0/grid/root.sh, from the grid home of the second node, generates an error
ORA-15032: not all alterations performed
ORA-15017: diskgroup "DATADG" cannot be mounted
ORA-15003: diskgroup "DATADG" already mounted in another lock name space
This is because of course the ASM instance on the first node is locking the disk group.
How can I extend ASM to the second node??
Any hel greatly appreciated

Ttys are not owned by group tty (and /dev/pts verses /dev/vc)

I just tried to do a "mesg y" in my terminal on my dekstop and got the error:
mesg: error: tty device is not owned by group `tty'.
So I chowned my tty to belong to group tty (previously it was owned by my generic group "users", of which b-con is a member) and it worked fine. I then checked my active ssh connection from my laptop and its tty *was* owned by group tty.
I assume there is something that is setting my created ttys to belong to the current user group by default instead of tty? Where might that be? I scanned all relevant bash profile/rc's and found nothing.
On a related note:
Right now I'm logged into my machine as normal, ie, into X and have a terminal running. I'm also logged in, as another user, via ssh. When I execute the "who" command, I see:
b-con vc/7 Feb 14 12:34 . 6894 (:0)
rj pts/2 Feb 14 22:02 00:03 9849 (192.168.0.4)
Why is b-con, the user logged in from the physical keyboard, shown as logged on vc/7 while the ssh user (rj) is shown as being on pts/2? User b-con has terminals on pts/0 and pts/1 open, so why is he reported as being on vc/7?
I was trying to use the "write" command to communicate between the two users, and b-con can write fine to rj on pts/2, but rj cannot write back to b-con because "/dev/vc/7: Permission denied". If I specify "write b-con /dev/pts/1" then I get the error "b-con is not logged in on pts/1". This is true because it's not my login shell, but it still is a shell I'm on.
Any enlightenment? I assume the latter half of my question boils down to login shells...

Yeah, it is pretty worthless. Designed for the pre-X11 days, I suppose.
Since the tty's are owned by user group of the owner, if the users you wish to communicate are of the same gropu you can use the primitive
$ echo text > /dev/pts/X
if you just want to move a little it of information around. You probably wouldn't want to hold a conversation that way, though. ;-)
Another way around it would be for both users to share a screen session (Google for tutorial). If you just open up nano you can hold a decent IM convo. For two people logged into the same machine, that's the best solution for interaction/conversation that I can think of.

Hm, check out ytalk (not in the repos).

Network destination already mounted when start Time Capsule backup after reboot

Just installed a new Time Capsule to replace my router, and noticed that when I reboot my home machine the intial attempt to backup always fails. (Running OS X 10.7.2 on a early 2011 15 inch MBP.)
Here is the Time Machine log:
Starting standard backup
Attempting to mount network destination URL: afp://[email protected]/Data
Mounted network destination at mountpoint: /Volumes/Data using URL: afp://[email protected]/Data
Failed to eject volume /Volumes/Data (FSVolumeRefNum: -105; status: -47; dissenting pid: 0)
Waiting 60 seconds and trying again.
Network destination already mounted at: /Volumes/Data
Failed to eject volume /Volumes/Data (FSVolumeRefNum: -105; status: -47; dissenting pid: 0)
Waiting 60 seconds and trying again.
Network destination already mounted at: /Volumes/Data
Failed to eject volume /Volumes/Data (FSVolumeRefNum: -105; status: -47; dissenting pid: 0)
Giving up after 3 retries.
Backup failed with error: 21
I then get a popup from Time Machine that says "The backup disk image "/Volumes/Data/Wayne's Macbook Pro.sparsebundle" could not be accessed (error -1).
I see "Time Machine Backups" on my desktop, and can access the drive via Finder.
If I use Finder to go into "Volumes" I can eject "Time Machine Backups" and the "Data" directory. If I then reselect the Time Capsule from the Time Machine settings window the backup works. Backups continue to work until the next time i reboot the machine.
Here is a log of a good backup run:

Is the problem because something is causing the system to mount the Data drive at startup, then Time Machine tries to mount it again? Any suggestions? I've done some searching in the support forums and FAQs but can't find anything that seems to match my situation. (No doubt due to my inexperience with Time Capsule / Time Machine. <grin>)
Many things for any suggestions and/or links to suggested solutions so I dont' have to take any manual actions after a reboot.

At least if yours is a new Time Capsule you can beat up on Apple Support to get them to fix it. So far no-one seems to have aroused Apple's interest in this issue. I expect Apple have judged it less critical than whatever other teething problems have shown up with the launch of iCloud. Apple are probably overwhelmed.
