Umount. To umount avoids execution of umount helpers such as umount.cifs. Indirectly by the umount(8) command when umount.cifs is in /sbinĭirectory, unless you specify the "-i" option to umount. Umount.cifs unmounts a Linux CIFS filesystem. $ umount.cifs /folderĬheck the manual of umount.cifs. And then, after proper unmounting, the best way to unplug a USB external hard-drive is: udisksctl power-off -b /dev/sdb. So first, you eject /dev/sdb (or umount everything). (Requires kernel 2.4.11 or later.)īut looking around I found something here. On Linux, eject will work, but will not really 'finish the job' regarding USB rotating drives. Detach the filesystem from the filesystem hierar- chy now, and cleanup all references to the filesystem as soonĪs it is not busy anymore. f Force unmount (in case of an unreachable NFS system). The OS password may differ from the password used to access the User Interface. Note: Ensure you have the OS password to access the Unitrends system’s command line. Mount -move //metro/released /TMPMNT/arcserver4Īfter this you'll have separate directories for each mounted filesystem, which you can explore and unmount at your leasure. Use an SSH client such as PuTTY to access the Unitrends system at the command line level. Mount -move //metro/released /TMPMNT/arcserver3 Mount -move //metro/released /TMPMNT/arcserver2 Mount -move //metro/released /TMPMNT/arcserver1 Mount -move //10.49.4.20/Released /TMPMNT/Released guestmount -a 2 -m /dev/sda mnt cmp sysroot/myfile mnt/myfile. unmount mkdir -p mnt /dev/sda becuase we have a raw filesystem. hard disk partitions, CD/DVDs and probably more. On Linux, you can unconfuse the situation by moving mounts so that each has its unique, non-overlapping mount point. Linux namespaces are a very lightweight form of virtualization (containers, to be more specific). If even that fails because umount is tripping on the multiple identical mounts, in desperation, unmount all cifs mounts: umount -a -t cifs Without using sudo, the system reports messages like 'Device or resource busy' or 'Transport endpoint is not connected', even if permissions are correct. Unmount them from the bottom up: umount //10.49.4.20/Released This answer refers to Ubuntu 20.04, but in general you need two steps to properly unmount a sshfs volume: i) kill the sshfs process and ii) use sudo to unmount. This is confusing both for humans and to the umount command. You have several directories that are mounted over other directories (the second mount on /mnt/arcserver shadows the first one and so on, and the mounts on /mnt shadow the prior mounts on /mnt/arcserver).
