Hi,
I have problem unmounting external FAT32-formatted USB drive on
10.0-RELEASE-p1 (with XFCE):
pacija at mephala:~ % umount /usr/home/pacija/mnt
umount: unmount of /usr/home/pacija/mnt failed: Device busy
lsof /usr/home/pacija/mnt gives no output.
I am not under mounted part in terminal or Thunar, I have no su session
left there.
I am mounting it as user, here are relevant lines:
pacija at mephala:~ % sudo gpart show da5
=> 34 975400893 da5 GPT (465G)
34 975400893 1 mbr (465G)
pacija at mephala:~ % mount
/dev/ada0p2 on / (ufs, local, journaled soft-updates)
devfs on /dev (devfs, local, multilabel)
tmpfs on /tmp (tmpfs, local)
procfs on /proc (procfs, local)
fdescfs on /dev/fd (fdescfs)
data on /data (zfs, local, nfsv4acls)
data/pacija on /usr/home/pacija/data (zfs, local, noatime, nfsv4acls)
/dev/da5p1 on /usr/home/pacija/mnt (msdosfs, local, nosuid, mounted by
pacija)
pacija at mephala:~ % cat /etc/sysctl.conf
kern.ipc.shm_allow_removed=1
vfs.usermount=1
pacija at mephala:~ % cat /etc/devfs.rules
[system=10]
add path 'usb/*' mode 0660 group operator
add path 'cd*' mode 0666
add path 'da*' mode 0666
add path 'pass*' mode 0666
add path 'xpt*' mode 0666
pacija at mephala:~ % cat /etc/rc.conf
...
devfs_system_ruleset="system"
...
pacija at mephala:~ % cat .gaminrc
poll /home/pacija/mnt/*
Any advices?

I only investigated the matter long enough to determine that there weren't any pending writes to the mount points. After discovering that this was going to be a consistent problem, with no /reasonable/ cause. I simply issue: umount -f /some/mount-point which never causes any problem, and always dis-mounts the mount points. --Chris> -- > Marko Cupa? > _______________________________________________ > freebsd-stable at freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-stable > To unsubscribe, send any mail to "freebsd-stable-unsubscribe at freebsd.org" > >
