General :: Mount: /dev/mapper/gegevens-Data Already Mounted Or /data Busy

Jul 14, 2010

A few months ago I have setup a server with three hard disks. The partition mapping the disks as follows:

Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x7ca36fee

[code]....

Now I have the following problem the LVM file system don't mount properly.If I open the mount point I see only a few files of the LVM disk. If I want to unmount the disk I get the following error:

umount /data/
umount: /data/: not mounted

If I want to mount the volume I get the following error:

mount -a
mount: /dev/mapper/gegevens-Data already mounted or /data busy

Ubuntu Installation :: Duplicate Drives In "Places" - Error "mount: /dev/sdd1 Already Mounted Or /media/Data Busy Mount: According To Mtab, /dev/sdd1 Is Already Mounted On /media/Data"

Feb 13, 2010

Just moved to Ubuntu from XP. Whole process has gone very smoothly, but left with a small problem (i.e. it isn't actually affecting usability) that I don't seem to be able to fix and can't find on forums/internet. I also have a problem with the Floppy drive, but I've seen that problem elsewhere in the forums.

It's a dual boot system with both NTFS and Ext4 drives. All are visible and fully accessible. I decided to convert one of the NTFS drive to Ext4. That appeared to be successful and was successfully remounted as an Ext4 drive. The drive label is "Data". I did have a bit of a problem getting it remounted so that I could see/use it under my log-in as opposed to just under root. It's at this point I think that I did something to create the problem.

I now have two entries for "Data" in drop down menu for Places. The true one is shown as a standard hard drive icon, but the false one is shown as a different icon - possibly an external drive icon (note that the floppy drive is also showing as the same icon and I can't access that, but I've seen that's a problem elsewhere in the forums).

I can write and read to the true "Data" hard drive. If I click on the other false "Data" icon, I get the message "mount: /dev/sdd1 already mounted or /media/Data busy mount: according to mtab, /dev/sdd1 is already mounted on /media/Data". If unmount the true drive and try to mount the false drive, the system mounts the true drive instead. If I log into nautilus as root, neither the false data drive or the floppy appear in the left hand panel.

Ubuntu Installation :: Kernel - Error "PHP Code: Mount: /dev/sdb Already Mounted Or /mnt/os Busy"

Feb 14, 2010

I was careless and deleted the Kernel using synaptic package manager. I was trying to delete the older entries but did not realize that I also selected the current one. Thus, I do not get an option to boot to Karmic at GRUB. It only shows the memtest entry and Windows XP. So I booted using the Ubuntu 9.10 LiveCD and tried the following:

1. sudo su
2. mkdir /mnt/os
3. mount /dev/sdb /mnt/os

At this point, I keep getting the following error: PHP Code: mount:/dev/sdbalreadymountedor/mnt/osbusyI tried rebooting, making a different directory to mount my sdb to but it keeps repeating the same message again and again.

General :: /dev/shm Not Mounted /dev Busy

Mar 2, 2010

Recently I was trying out a boot disk I had made, and basically, I switched it off several times due to it booting the completely wrong kernel. Now, I'm getting to the stage "Checking File systems" and then comes up [Failed]. I then get a message saying Reboot required, and that it will reboot in 15 seconds, just a few seconds before it reboots I get "/dev/shm not mounted, /dev busy" or something similar.

I've booted up my sysresccd, ran "fsck.ext4 -fcv /dev/sda2" to force a check and scan for any bad blocks, it came up clean, then I rebooted and got the same error, so I copied the kernel and system.map over to /boot to make sure there's no corruption and reinstalled initscripts and util-linux-ng, rebooted, same error.Tried different kernels, I've checked fstab and menu.lst, no problems there, so I still don't get why I still get the same problem.

Ubuntu :: Mounted Data Stored Where?

Jul 5, 2011

Does anyone know WHERE Ubuntu stores the location for mounted external filesystems and/or servers? I can mount other computers on my network, display the files etc., but CAN NOT find where Ubuntu saves the mounted system data and locations.

I mount a PC on the network, open a file manager window and see everything, but can't find where Ubuntu has that system "mounted". It's NOT in the /mnt folder or anywhere else I can see. I need to find this location to feed it to a program that sets up a remote server. I can't setup the server because the program only "looks" at the local root and doesn't find any external mounts.

General :: Accessing Data Under A Mount Point?

Apr 10, 2010

I'm using ext3 and I have my / partition on sda3. This is a full install, it has /bin /home etc etc on it, the only thing I have is sda1 is /boot and sda2 is swap.

I've configured my system to mount sda4 as /home/user as the system boots up, which puts all of my data on sda4.

My question is this. How do I access any data left in (sda3) /home/user? (Because trying that won't work). Is there some way to use a direct path? Like /device/sda3/home/user?

Ubuntu :: Can't Access Data On Mounted Partition After Upgrade To 10.04

May 4, 2010

Yesterday, I upgraded to the 10.04 verion of xubuntu. Looks fine. However, I keep my data on an NTFS partition of my dual boot laptop, and am finding that I can't access it.

I have a symbolic link to that mounted partition, and when I click on it, I can see the first level of folders, but I can't execute them (even though they seem to be set to 777) and I can't open anything...

General :: Mount A Hard Drive With Pre-existing File System And Data?

Mar 23, 2010

I had a drive that kept kernel panic'ing so my data center recommended using the spare hard drive to reinstall OS on, and import the data from the old drive. (they checked the hardware, it wasn't the hardware) The new install is done, and I need to mount the old drive and get backups off it since my data center does not provide management whatsoever.

It's the same OS on both (Cent OS 5.4 32-bit) I'm an advanced user on windows, but linux gets me. I can ssh in, do basic stuff like setup IP ranges and restart services. I normally navigate the box through SFTP so I have a gui. WHM shows me my drives as such

Found Disk: hda
Found Disk: sdb

so I'm assuming SDB is my old drive and the drive I need to access. I attempted to follow instructions on

cyberciti.biz/faq/freebsd-adding-second-hard-disk-howto/

but I'm assuming FreeBSD would work differently and I wasn't totally sure what the labels of the file systems should be.

General :: USB NTFS Disk Suddenly Won't Mount - Partition Gone / Repair It And MBR Without Losing Data?

Sep 12, 2009

Just ran into an uncomfortable problem. I usually never save any documents on my machine, and keep all my stuff on an external USB hard disk. (an 80GB TrekStor DS microdisk q.u)
Well yesterday this disk just would not mount.
Read through related posts but nothing seemed to work. Even tried it on a Windows machine.

Tried TestDisk utility. Found nothing wrong with the drive, but still could not repair the MBR.log code...

Palimpsest Utility recognized the drive, but just will not let me do anything with it except format it.

How can i repair the partitions and MBR without losing all my data?

OpenSUSE :: Does KMail Account Data - Such As Login Data / Names Of Pop / Smtp Servers

Where apart from ~/.kde4/share/apps/kmail does kmail keep account data, such as login data/names of pop/smtp servers? I wanted to install an entirely clean version of kmail, so I uninstalled/re-installed kmail via YAST. I manually deleted ~/.kde4/share/apps/kmail. After installing kmail I found that the account data of my Yahoo account were still listed in the kmail configuration panel. Shall I delete the Yahoo account within kmail prior to uninstalling the kmail package?

Ubuntu :: Excel Data Shrinks To The Small Scale - Unreadable When Copy Data From Another Spreadsheet Onto The New One

I've been using Excel from OpenOffice with moderate success for the last year. Now I've just tried to open a new spreadsheet and I'm suddenly getting a highly condensed view. The cells are about 1mm X 4mm. If I expand them by selecting and dragging, then try to copy data from another spreadsheet onto the new one, the data shrinks to the small scale -- unreadable.

Ubuntu Servers :: Access The Data In .fbd Data File

Feb 19, 2011

We purchased a new database system at work last October, ditching the old system because of a lack of support from the vendor. This is a retail Point of Sale and Backoffice database system. I am not sure what system the new one runs on, but the system we replaced was a Firebird data base. The reason I am posting is because we are now in need of the information contained in the old database which was not completely imported into the new system.

Basically the problem is this: The database in on a Windows XP system and I found a copy of SQL Manager Lite 2008 on the system, which after quite a bit of studying, I figured out how to extract the database into a removable file. I have this file (178MB) on a USB stick in a file called Backoffice.fbd.

My studying suggests to me that I can get into this database with MySQL. I have never used this and have no clue how to do this. All I want to be able to do get into the database and create tab deliminated spreadsheet files for each of the database sections (Customers, Repairs, Sales History, stock files, etc.) Is it possible to do this with Ubuntu and MySQL and if so, can expert suggest one or two things to get me started. While a guided tutorial would be nice because I am not an expert, I am willing to learn on my own if someone could point me in the right direction.

Programming :: Data Directory In Automake - Data Is Always Read-only ?

May 9, 2010

I have some data files that should be distributed with my program. Using dist_pkgdata_DATA in Makefile.am, I get these files installed to /usr/local/data/share/package-name. The problem is that data is read-only, and my program needs to modify it. Playing with dist_sharedstate_DATA, dist_localstate_DATA, dist-data_DATA varibles, I got different installation directories, like /usr/local/com, usr/local/var, but data is always read-only.

How can I distribute modifiable data files with my package? I need some common directory for all users, or maybe local data in a user directory.

Fedora :: Mount And Unmount Data Partitions

Jul 29, 2011

I'm in the process of building a new Fedora machine. I use the machine for a VMWare server, the file server for the house as well as a Linux desktop for work.My current machine has a single 1.5GB hard drive. The new machine will have a mirrored RAID drive(2TB). I'm also contemplating using a smaller 250GB drive for the OS installation. I would then divide up the 2TB drive into /home and /var/lib/vmware partitions where the bulk of the data would reside.The goal is to be able to unmount the /home and /var/lib/vmware partitions when I need to upgrade the OS version with the data intact and remount them once the new install is complete.

The goal is to keep the family network file shares and my Virtual machines intact while reinstalling the new Fedora OS from scratch. In theory it should work. I just want to mak an (in)sanity check to ensure it will work in practice.

Ubuntu :: HDD Failed / Anyway To Mount It To Recover Data?

Feb 28, 2010

It seems my 320gb HDD has bitten the dust. The timing couldn't be more ironic as I have spent a couple of days tidying the files on it to burn them to disk.

This is an ntfs drive that had indicated 4 bad sectors but up until today (backup day) was fine. I am unable to mount it and in fact it is causing some sort of conflict with the OS drive and wont let the system boot up successfully.

I am going to try using a windows based PC tomorrow to see if I can rescue the data.

Are there any 'other' tricks to try and mount it with ubuntu that I may not have tried so far? I have tried-

mkdir /media/disk
fdisk -l to establish it's name which was /dev/sdb1 when it was all working but it isn't reachable and doesn't show in the places menu or in any of the menus when using a live CD to get round the HDD clash.
sudo mount -a used in desperation after the mkdir but nothing.

I rejigged the cabling inside the PC to make the HDD a secondary master as it was a slave on the primary IDE to start with in the hope that the system would boot up normally but to no avail.

Ubuntu :: How To Mount Partitions For Data Access

Jul 3, 2010

I figured I could just go in to my Kubuntu desktop and look at the drive. But it has only a lost and found and grub folder with a few files on the root named config-[version]-server (note this is a SCSI). Guessing I'm looking at the boot partition? So how do I mount the other partitions? When I do a fdisk -l I see 3 sdb 1,2,3 (2 and 3 are large, 1 is my boot partition) but when mounting them I get wrong fs type. I was sure its ext3 ( also tried 2 and 4 )? I just left the default 7.04 fs when I installed it. I'm able to put it in my desktop and my server but for the life of me I can figure out how to get at the data.

Ubuntu Installation :: Can't Mount Data Drives

Jan 9, 2011

I installed 10.10 on my workstation but now my system refuses to mount two existing two data drives that were already there... sudo mount /dev/sdc /mnt/data-b gives me: mount: unknown filesystem type 'isw_raid_member'

I didn't change any BIOS settings... My BIOS is not configured for RAID at all, that setting reads AHCI, which should be okay for my kernel (using the stock 2.6.35-24).

I tried to force mount one of the drives with sudo mount -t ext3 /dev/sdc /mnt/data-b

but this gives me an even stranger message:
"/dev/sdc already mounted or /mnt/data-b busy (neither of them are true...)

It's mainly the "isw_raid_member" thing that troubles me... I didn't and don't have a RAID system at all..

CentOS 5 :: Mount Bsd/386 Partition To Recover Data

Jul 4, 2009

I need to mount a bsd/386 partition on my hard drive to recover data. I am running the latest CentOS 5.3, downloaded and installed in the last week.My searches have turned up a mount command, that does not work.

[root@new-host-2 ~]# mount -t ufs -o fstype=444bsd /dev/sda3 /mnt/bsd
mount: unknown filesystem type 'ufs'
[root@new-host-2 ~]# mount /dev/sda3 /mnt/bsd

[code]...

So, is there a patch to get mount -t ufs working?is there a patch to get bsd/386 filesystem type? have not build a kernel before, so I would like to avoid that, but I will attempt it if I have no other options.
