Server :: CIFS Mounted Multiple Times / Error "Device Or Resource Busy"?
Feb 10, 2011
I have a little problem with my RHEL5.5 IA64. I mounted a Windows directory with 'mount -t cifs'. After a little while someone else mounted the same windows directory in the same mountpoint. The output from 'mount -v' shows me that the same directory is mounted twice in the same mountpoints. I cannot unmount it, not even with the force option. The error is "Device or resource busy". There are no open files in the shared directory and no one using the directory or subdirectories.
So I cant seem to be able to install fedora 15. I think it is the disk. I have windows 7 already installed (and would like to keep it) It was installed on the end of the hard drive leaving a 100 GB chunk in the center of the drive open and unformatted (this may be the problem). Anyway I used the live cd and tried to format the unformatted partition to exf but it gives me this error
Code: Error creating partition: helper exited with exit code 1: In part_add_partition: device_file=/dev/sda, start=105906176, size=104752742400, type=EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 Entering MS-DOS parser (offset=0, size=500107862016) MSDOS_MAGIC found found partition type 0xee => protective MBR for GPT Exiting MS-DOS parser Entering EFI GPT parser GPT magic found partition_entry_lba=2 num_entries=128 size_of_entry=128 Leaving EFI GPT parser EFI GPT partition table detected containing partition table scheme = 3 got it got disk new partition added partition start=105905664 size=512 committed to disk Error doing BLKPG ioctl with BLKPG_ADD_PARTITION for partition 2 of size 105905664 at offset 512 on /dev/sda: Device or resource busy
Do I have to reinstall windows for this to work or is there something I can try to do.
which run without errors but an attempt to mount throws up the above error as well as saying - you must specify the file type (tried that) - and fails to mount. I've tried using YaST to format and encrypt it which throws up the same error when I run mount but actually does actually mount the filesystem Googling around has brought up info saying that it's probably a race condition brought on by invalid udev rules. I've got a (mostly) working system and the udev rules documentation leaves more confused than when I started.
I rebooted my server and out of nowhere the RAID5 array won't assemble. I've tried everything I could think of to reassemble the thing. I fear that the array is ruined, but I can't imagine how. Here are various bits of information: The simplest failure (with and without partition numbers, which have not been needed in the past):
Code:

When I try to suspend to RAM my Fedora 12 system (2.6.31.12-174.2.22.fc12.x86_64), Screen goes blank for about 15 seconds, and then comes back as if nothing happened. I see the following error in /var/log/pm-suspend.log
I am trying to set up a mdadm raid in a new machine that I am building as a home theatre PC. the machine boot just fine from /dev/sdc running ubuntu 9.10 However in gparted /dev/sda and dev/sdb show to be part of /devmapper/sil_ajbicfacbaej
Both dev/sda and /dev/sdb were drives that used to be part of a sil hardware raid on a previous machine. I would like to use them as a new mdadm raid on this new machine the old hardware card was really quite slow. the drives are now pluged into the MB and should be much faster there.
I am dual-booting my Gateway laptop with Windows XP Media center Ed. and Ubuntu Notebook 10.10. Several weeks ago I was in the midst of downloading a program from the software center and my system starts running slow (this is in the Ubuntu kernel, not the Windows OS). So I decided to cold-boot the laptop in mid-download. When it boots back up, I get dropped to a grub-rescue menu that states the following:
Code:
Now, the only way I can even remotely use my laptop at the moment is to use my Live USB with the corresponding version of Ubuntu Netbook 10.10 or the Live CD I made with Ubuntu 10.04 on it (I'll explain why I made this below).
I read somewhere that I need to run fsck on my device to try to fix the partition, which btw my Ubuntu partition on my device is /dev/sda5, and before someone suggests it, I even tried using GParted and it doesn't work.
The reason I made a 10.04 CD is because I read somewhere that using the fsck from 10.04 might be more effective (for whatever reason) than the 10.10 fsck version.
I'd also like to add that I'm incapable of booting onto my Windows OS at all, yet I can access the partition from my Live CD/USB. the Ubuntu partition however, I can neither access or mount.
I tried running fsck on the entire device partition table, and I get the following:
Code:
This is me running fsck from the 10.04 version, I get a similar msg from the 10.10 Live USB but replace fsck.ext2 with fsck.ext4 in the message.
After upgrading to fedora 15, I have problems mounting XFS filesystem.

Device is not mounted, and directory is not in use, it has just been created. There is nothing in log files that could remotely point the cause. After removing device (echo 1 > /sys/block/sdb/device/delete) and reattaching it, disk started working.
My son's netbook with 10.10 netbook remix failed to boot. Using the Live install CD and Gparted I couldn't repair the EXT4 filesytem. The error reported was:
e2fsck : Device or resource busy while trying to open ...
After trying many solutions and web searching I decided to try a different live CD and tried Knoppix 6.4.4
Using the command interface I typed e2fsck -v -f -y /dev/xxxx (xxxx = your device). This worked first time and the machine rebooted without hesitation.
Pulseaudio got installed by default here during installtion. Since I don't want it I first ran "systemctl disable pulseaudio", "pulseaudio --kill", then without rebooting I use mpd with alsa alone and it worked fine.
But then i rebooted, and now all applications, mpd, mpv, chromium etc just says that alsa returns with "Device or resource busy", tried rebooting again with no effect.
The soundcard appears as card 1 according to the output of "aplay -l", and defined that card 1is suposed to be default with this in "/etc/asound.conf":
Code: Select allpcm.!default {   type hw   card 1 }
ctl.!default {   type hw   card 1 }
It occurred to me that there might be an issue with permissions to the soundcard so I ran "ls -l /dev/snd"
Code: Select alldrwxr-xr-x 2 root root    80 Mar 31 03:27 by-path crw-rw----+ 1 root audio 116, 8 Mar 31 03:27 controlC0 crw-rw----+ 1 root audio 116, 2 Mar 31 03:27 controlC1 crw-rw----+ 1 root audio 116, 12 Mar 31 03:27 hwC0D0 crw-rw----+ 1 root audio 116, 7 Mar 31 03:27 hwC1D0
When installing I am selecting the manual partitioning scheme( I have arch on another partition). After I have selected my custom partitions and their mount points it starts the installation but almost immediately it gives the error message that it cannot create a partition on the specified one, as it is used by the OS. I have also tried to create partitions through gparted in the live session but to no avail. I am sure that no partitions are mounted or in use by the system, I have checked this using the mount and fuser commands. I also tried the oem installation but the result the same.
Trying to complete a RAID 1 mirror on a running system and have run into a wall at the last part. I can't add the active physical disk to the mirror. This is on a Centos 5.6 x86_64 system. Anybody know where to go from here? I've tried adding the nodmraid line to the kernel boot line with no luck. Tried removing the logical volumes from LVM, but it won't let me. Not a Linux newbie, but haven't set up a RAID in a long time.
[root@blackbox-0-2-e3-23-72-c5 ~]# mdadm /dev/md1 --add /dev/sda2 mdadm: Cannot open /dev/sda2: Device or resource busy
Something weird happened last night and my raid5 failed. I am trying to re activate it and see if my data is dead or what. When I run mdadm -Asv /dev/md0 I get
Code: mdadm: looking for devices for /dev/md0 mdadm: cannot open device /dev/dm-1: Device or resource busy mdadm: /dev/dm-1 has wrong uuid. mdadm: cannot open device /dev/dm-0: Device or resource busy mdadm: /dev/dm-0 has wrong uuid. mdadm: cannot open device /dev/sde2: Device or resource busy mdadm: /dev/sde2 has wrong uuid. mdadm: cannot open device /dev/sde1: Device or resource busy mdadm: /dev/sde1 has wrong uuid. mdadm: cannot open device /dev/sde: Device or resource busy mdadm: /dev/sde has wrong uuid. mdadm: cannot open device /dev/sdd: Device or resource busy mdadm: /dev/sdd has wrong uuid. mdadm: cannot open device /dev/sdc: Device or resource busy mdadm: /dev/sdc has wrong uuid. mdadm: cannot open device /dev/sdb: Device or resource busy mdadm: /dev/sdb has wrong uuid. mdadm: cannot open device /dev/sda: Device or resource busy mdadm: /dev/sda has wrong uuid.

I've upgraded my squeeze box to linux kernel 2.6.32-5. But it shows mounting "here is the uuid of / " on /root failed: Device or resource busy while booting.Here is the menuentry of linux kernel 2.6.32-5.
I have an audio recorder that doubles as a music player. It can play WAV files. So I put in some WAV files and they are out of order, even if they are named numerically. Read somewhere about a little CLI software called fatsort so I installed. The device is located at /dev/sdc. So naturally I write fatsort /dev/sdc, it says something about permission. So sudo fatsort /dev/sdc. Thing is, it says:
Code: sort_fs: Device or resource busy! If I "eject" it (unmount) then it says something about cannot read boot sector or headers. On Windows there is FAT Sorter. It does not work in WINE. So every time I put something in, I have to get to a Windows computer to sort it. It seems like fatsort is the only program that sorts FAT systems in Ubuntu/Linux.
I'm currently running Ubuntu Maverick - 2.6.32-30-generic. I recently bought a Garmin eTrex Vista H, which connects via usb (from my reading, it looks like older versions connected over serial). Well, like so many before me, I can't seem to write to or read from the device via gpsbabel.Originally tried to read anything from the device (I have one waypoint in there) via:
Code:
gpsbabel -i garmin -f usb:
It returned "Found no Garmin USB devices." I then tried turning on the eTrex. Doing the same while locating satellites just does nothing - I have to escape from the command in terminal. Trying again produces the error:
Quote:
Claim interfaced failed: could not claim interface 0: Device or resource busy
After doing some research, I unblacklisted and then reblacklisted garmin_gps. I also went into
as directed in this . Everything seemed to be correct.I then followed some other advice found here and created the policy under /etc/hal/... Still no luck!
We have a homegrown process that runs on a windows box and produces a csv file. We mount the directory these are output to using autofs/cifs and then process them using a program on our linux database servers.
Is there a way from linux, looking at the cifs share, to tell if the target file is currently in use by a process on the windows box? We are having issues where an incomplete file is being processed occasionally.
I installed mdadm fine and all and proceeded to run:mdadm --create --verbose /dev/md0 --level=stripe --raid-devices=2 /dev/sda /dev/sdbWith sda being my primary hard drive, and sdb being the secondary.I get this error message upon running the command"mdadm: chunk size defaults to 64Kmdadm: Cannot open /dev/sda: Device or resource busymdadm: create aborted"I don't know what's wrong!
We recently had an issue with "cat /proc/mount" telling us that a CIFS file system was mounted, even though the mount was not working correctly. So we're not sure if we can trust linux to report malfunctioning mounts, so we're planning on adding a specific file on the mounted file system, and verify the mount by reading this file from the client side (linux). If linux fails to read it, we know that the mount have failed. But before we go ahead doing this I thought I'd just hear how others are doing this sort of thing - how do you make sure that mount points are up and working?

EDIT: I just saw that I've posted in the security area, not in the server area. How do I move it?
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/sdb already mounted or /mnt/os busy I tried rebooting, making a different directory to mount my sdb to but it keeps repeating the same message again and again.
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.
My 5.5 server has crashed on my multiple times over the past few weeks. I have 2 terabyte drives mirrored.It automatically reboots and seems to run fine after rebooting.I've attached a copy of the /var/log/message to this post.I was unable to paste file.I'm not if a bad disk is causing the problem or not.
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.
My recent issue is that when i start firefox 3.6.7 OS 9.10 is that the terminal will pop up and have this error: (firefox-bin:2690): GLib-WARNING **: g_set_prgname() called multiple times. I can only have firefox running when the terminal is running.If I close the terminal firefox will close as well
Having problems with external hard drives. I may be wrong, but I suspect they originated with an upgrade to 10.04 last Christmas. Around that time I also started using Amazon's S3 storage system, and, as a consequence, I stopped using my WD 80G external drive, previously used to backup my important files.
A week or so ago I decided to start using the WD drive again. I can't remember exactly what I did, but it wasn't happy - never caused any problems before. When I plug it in, the on-off light as the front keeps flashing on and off, and when I try to remove the drive I get the message: Error unmounting volumne An error occured while performing an operation on "My Book" (Partition 1 of WD 800BB External): The device is busy
Details: Cannot unmount because file system on device is busy Assuming the device had died - it's about 5 years old - I bought a 160G Samsung S-Series drive - my but they do look neat! Unfortunately, this doesn't seem to have solved my problem. I plugged the new drive in, and it happily appeared on my desktop. It seemed a good idea at the time, but I then started to format the drive - using the default option of FAT. All went well at first, but then the format process stopped.
My new Samsung drive now seems to be operating pretty much as the WD device, I can't copy to the drive, and attempts to unmount it generate a response similar to what's happening with the WD drive. Currently, although plugged in, I can't see the drive on my desktop, although it appears under Places. However, when I try to mount the drive, I get the message: Unable to mount SAMSUNG A job is pending on /dev/sdb1
How do I find out "why" the mounted virtual drive is busy? All windowed programs are closed out. I assume a background program is using the resource? All was fine until about a week ago.
I have a WD MyBook World NAS share mounted with the following options (I tried also other options):Code:cifs nouser,atime,auto,rw,nodev,noexec,nosuid,nodfs,nounix,guest,uid=0,gid=0,file_mode=0777,dir_mode=0777The cp -a, touch, etc. commands can change the file time if the root is executing the command (means NAS supports time setting), but as an user I can't change the file time - with an exception of changing the time to the current time. For an illustration see below:
