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.

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

Is there any method of forcibly umounting an NFS mounted directory? We have a test environment managed under puppet that is also our DR environment. In a DR scenario we''ll be umounting all NFS shares from out test array and remounting to our DR array. However, as this is a test environment we have users logged on, so when Puppet attempts to unmount the test directories, it fails

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

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'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

OS: EL6 - sometimes I use kpartx -a /mnt/.../lvdisk.img to map the partitions and mount them via /dev/mapper/loop0pX After using the disk (unmounting it) I noticed that detaching such mapping via kpartx -d does not result in freeing up the loop devices. Results: System reboots shows that the filesystem where lvdisk.img is located can't be unmounted. lsof, fuser, ps does not show

Hi, I want to rename some volume groups and logical volumes. I was not surprised when it would not let me rename active volumes. So I booted up the system using the CentOS 5.5 LiveCD, but the LiveCD makes the logical volumes browsable using Nautilus, so they are still active and I can't rename them. Tried: /usr/sbin/lvchange -a n VolGroup00/LogVol00 but it still says: LV

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.

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

Greetings, I am trying to use vfs_shadow_copy2 with samba samba-4.2.7. I have a share exported at /export/smb400/. A snapshot of the share is on a separate block device, which is mounted at /export_shadows/volume-00000001/@GMT-2016.02.08-11.48.00/. Samba configuration for the share is: vfs objects = shadow_copy2 shadow:snapdir = /export_shadows/volume-00000001 shadow:fixinodes = yes (Note: I

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.

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

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

Hey all, I've been fighting a samba share/unmount problem for several days now and may have found a bug in the connect/disconnect code. Basically, it seems that while everything claims to free the connection to the share, it doesn't actually happen. This is me closing ALL windows to the server: log.smbd: jon1 (192.168.200.2) connect to service disc1_pc_test as user breakit (uid=501

Yes, really. I've got hundreds of the damn things here at home, and I want to go through them and get rid of them all. But... to do that I want to read them. I have both a 5.25" and a 3.5" drive, both are plugged in, but in the BIOS, all I see is the 3.5". Fine, I figure I'll take care of those. Nope. I see /dev/fd0 once I've booted up, but neither konqueror nor

Hi Jeremy, The use case is that we want to automatically rotate the snapshots. For example, we want to keep 24 hourly snapshots, and every hour we create a new snapshot and unmount the oldest one. But since customers can be restoring from the oldest snapshot right now, it is not deterministic when we will be able to unmount the oldest snapshot. So at that moment we want all active restore
