Hello:

This occurs in openSUSE 13.1 and its deafult KDE4 installation.

User abc is logged in at graphical display 0 through kdm inot KDE4 session.

He inserts a USB stick which is recognized and mounted automatically by KDE4 device manager.

df -h /dev/sdb1 978M 94M 884M 10% /run/media/abc/KINGSTON

The he wants to unmount it in a login shell (ssh session):

umount /dev/sdb1 umount: /var/run/media/abc/KINGSTON: umount failed: Operation not permitted

umount /run/media/flexys/KINGSTON/ umount: /run/media/abc/KINGSTON: umount failed: Operation not permitted

Is this normal? How can the user unmount the device? Not by suing to root but as a normal user.

User must use the graphical app provided, on my system it is: Device Notifier Icon is in the "System Tray".

I don't recall that w/o making "special" provisions, <user> was every permitted to mount/umount system devices.

Dynamically mounted devices also appear at the bottom of the "Places" panel (toggle w/ F9) in Dolphon. Right-click the device and select 'safely remove." [oS 13.2 KDE4 (4.14.9)] -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Devices are most likely mounted via udisks so udisksctl unmount could be used to do it. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I can't seem to get udisksctl to cooperate. I plugged in a test USB stick and it was auto-mounted: /dev/sdb1 --> /run/media/carlh/USB20FD /dev/sdb1 on /run/media/carlh/USB20FD type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=100,fmask=0022,dmask=0077,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2) ~> udisksctl umount /run/media/carlh/USB20FD Unknown command `umount' Hmmmm ... okay, I guess I can understand "unmount" vs "umount" in this context. ~> udisksctl unmount /run/media/carlh/USB20FD Usage: udisksctl unmount [OPTION...] Unmount a filesystem.

Unmount a filesystem.

Try "udisksctl unmount -b /dev/sdb1" or "udisksctl unmount -p /run/media/carlh/USB20FD"

~> udisksctl unmount -b /dev/sdb1 Unmounted /dev/sdb1. Note: The device remained visible in the "Places" panel in Dolphin until I physically unplugged it. Contrast that with it actually disappearing when you right-click and select "safely remove." As I understand it, the "safely remove" procedure powers USB devices down in addition to dismounting them, which is great when real (mechanical) USB attached external hard drives are involved.
