I'm on 12.04 in my case I'm seeing libvirtd continuesly respawning and mounting the device some how. umount /var/lib/schroot/mount/precise-2d97fb31-1cae-47e4-a363-0a652a518610/dev root@bork:~# lsof | grep /var/lib/schroot/mount/precise-2d97fb31-1cae-47e4-a363-0a652a518610/dev dbus-daem 19780 messagebus 0u CHR 1,3 0t0 5826 /var/lib/schroot/mount/precise-2d97fb31-1cae-47e4-a363-0a652a518610/dev/nul tgtd 19794 root 0u CHR 1,3 0t0 5826 /var/lib/schroot/mount/precise-2d97fb31-1cae-47e4-a363-0a652a518610/dev/null libvirtd 19913 root 0r CHR 1,3 0t0 5826 /var/lib/schroot/mount/precise-2d97fb31-1cae-47e4-a363-0a652a518610/dev/null
usually attempting to kill the processes just ends up in them respawning and magically remounting the directories. I can tell this by I see message in dmesg to the effect of libvirt-bin terminated. Then right below it I see another message saying libvirtd-bin process e ended respawning. The main culprits is usually udev though. rebooting is problematic too if the schroot daemon picks up old sessions in the /var/lib/schroot/sessions directory and mounts those directories. :| Seems the only sure fire way I've found is to delete the sessions directory and reboot. then I can umount them. And yes they misteresly are mounted some how. I can't ease the schroots root directory unless I do this process and I was useing schroot so I could quickly ease a linux environment and start from scratch. Whats the status on this bug. It seems like the inability to forcefully umount the directories is the main cause of head ache. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/917339 Title: 10mount: umount: /<<CHROOT>>/dev: device is busy To manage notifications about this bug go to: https://bugs.launchpad.net/schroot/+bug/917339/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
