similar to: Force unmount??

Greetings - Ok, I made a mistake that I need to fix. Fortunately it is not a destructive mistake, but I need some advice on how to correct the problem. CentOS 6.3 host system named Earth I was creating some new logical volumes within my exiting volume group for a new virtual machine using the LVM GUI. When I created the LV that I plan to use for root partition of the new VM (Bacteria) I

I''m running into a situation where I can''t unmount a mounted snapshot. It shows "busy" even though neither lsof nor fuser show any open files. Umount -f doesn''t work although umount -l does. Is there anything else I can do to debug this scenario or to clear the busy status myself? Or am I down to rebooting each time? This is on stock ubuntu-10.04, x86.

Hi all, i?m not sure if my problem is realted to ocfs2 or to drbd, so i x-post this post to both lists. I?ve drbd-volume [v 8.3.9] (dual-primary) with ocfs2 [v 1.6.3] as a filesystem. If I add a "bind-mount" like /var/log/ispconfig/httpd/blog.schaal-24.de /srv/www/clients/client2/web323/log none bind,nobootwait 0 0 to /etc/fstab i`m unable to run umount /srv/www (which is

* PATCH FOR DISCUSSION ONLY - NOT TO BE APPLIED * Colin suggested something which seems eminently sensible: https://bugzilla.redhat.com/show_bug.cgi?id=916780 I've been through a couple of rounds of trying to implement this. I started with adding the option as suggested to the guestmount program, but it tended to make the guestmount program more complex. More importantly, adding the option

Hi, on an EL5 XEN DOM0 system I have following volume $ df -h /srv Filesystem Size Used Avail Use% Mounted on /dev/sdc1 917G 858G 60G 94% /srv that partition was used by virtual machines but they were all halted. service xendomains stop $ xm list Name ID Mem(MiB) VCPUs State Time(s) Domain-0

Using the Disk Management GUI. I mounted the floppy copied a file to it by dragging from one Nautilus window to another Then I tried to unmount the floppy and got an error that the device (/media/floppy) was busy. This is not the first time this has happened to me. And it does not happen all the time. In fact, yesterday I did the exact same steps with no problem.

Since the first patch: - The program is now called 'guestunmount'. - I tested the --fd option and it appears to work. - You can now control retries / quiet. - Revised man pages. - Includes tests. I'm just running through the automated tests now. Rich.

I have mounted a win98 machine from a ML8.1 samba 2.2.2 The win98 machine, as all windows machines do, crashed on me. Now i can't unmount the mounted folder, If i do it from cli, i get umount usr/Cad12: device busy. If i try and cd to that folder, the console freezes and only kill application will shut it down. I tried as su and on another Virtual console as root, but it will not umount.

Hello, on 9.1-R, I highly appreciate the new jail(8) and jail.conf capabilities. Thanks for that extension! But I have one problem: If I want to stop a jail with 'jaill -r jailname', I get "umount: unmount of /.jail.jailname failed: Device busy" It seems to me that the order of fstab.jailname entries are not reverted by jail(8) when shutting down/umounting. My C skills

Hi All, How do I unmount an NFS share when the NFS server is unaivalable? I tried "umount /bck" but it "hangs" indefinitely "umount -f /bck" tells me the mount if busy and I can't unmount it: root at saturn:[~]$ umount -f /bck umount2: Device or resource busy umount: /bck: device is busy umount2: Device or resource busy umount: /bck: device is busy This

Hello, while playing with new jail features, I recognized that manually umounting doesn't work as I'd expect. After jail has been destroyed, the following mountpoint is active: /dev/gpt/jailname1ROOT on /.jail.jailname1 (ufs, local, read-only) There was var mounted to /.jail.jailname1/var but that sucessfully umounted. 'fstat' also shows no open files in /.jail.jailname1 But

I'm trying to understand why a normal user is not allowed to unmount their USB stick? I think it is most likely a udev rule. does anyone know ? Thanks Phil.

Doing this would reliably fail with -EBUSY for me: # mount /dev/sdb2 /mnt/scratch; umount /mnt/scratch; mkfs.btrfs -f /dev/sdb2 ... unable to open /dev/sdb2: Device or resource busy because mkfs.btrfs tries to open the device O_EXCL, and somebody still has it. Using systemtap to track bdev gets & puts shows a kworker thread doing a blkdev put after mkfs attempts a get; this is left over

when you have something smbmounted with samba.. //ADMINISTRATOR@CALVIN_SR/M$ 112G 71G 41G 64% /mnt/samba and you unmount it and it gives you /mnt/samba is busy Im absolutely positive that I am NOT in the /mnt/samba dir, nor is anyone else. is there any way to force it to unmount? Jason

It works, but I should delete if (guestfs_umount_all (destg) == -1) ??? exit (EXIT_FAILURE); inmain() function and /* Clean up. */ ? if (guestfs_umount_all (srcg) == -1) { ??? pthread_cancel (threaddata->mainthread); ??? exit (EXIT_FAILURE); ? } in the start_scrthread() function or it will return an error after the program finish: libguestfs: error: umount_all: umount:

I'm attempting to build a virtual disk image for qemu of CentOS4 on CentOS4. I'm having a problem after using yum --installroot to put a minimal filesystem on a partition located within the virtual disk. When I go to unmount it, I get "device is busy" errors. I know that I haven't left anything using that filesystem and lsof doesn't show anything, so I'm wondering
