umount /cediback2 [sometimes works, sometimes not]
Being rather old-fashioned for a minute, I wonder if you need to:
sync has been made largely obsolete but I wonder whether the O/S knows that it still has data to write and so won't let the filesystem go.
Just something I would try.
That might explain why sometimes it works and sometimes it doesn't.
I'm trying to unmount a file system, but umount says the device is busy. A fuser -c /myfs tells me that nothing on this fs is in use. Any idea?
Oh, and btw, why isn't my signature beeing displayed? Show user's signature is enabled and I have entered one :/ (10 Replies)

A product I am working on manages storage. We are currently porting it from Solaris to Linux.
The product allows its user, among other things, to add and remove file server volumes, where these volumes are exported using the NFS or the CIFS protocol.
The problem is that when the user requests to... (5 Replies)

umount
UMOUNT(8) BSD System Manager's Manual UMOUNT(8)NAME
umount -- unmount filesystems
SYNOPSIS
umount [-fv] special | node
umount -a | -A [-fv] [-h host] [-t type]
DESCRIPTION
The umount command calls the unmount(2) system call to remove a special device or the remote node (rhost:path) from the filesystem tree at
the point node. If either special or node are not provided, the appropriate information is taken from the list of filesystems provided by
getfsent(3).
The options are as follows:
-a All the filesystems described via getfsent(3) are unmounted.
-A All the currently mounted filesystems except the root are unmounted.
-f The filesystem is forcibly unmounted. Active special devices continue to work, but all other files return errors if further accesses
are attempted. The root filesystem cannot be forcibly unmounted.
-h host
Only filesystems mounted from the specified host will be unmounted. This option implies the -A option and, unless otherwise speci-
fied with the -t option, will only unmount NFS filesystems.
-t type
Is used to indicate the actions should only be taken on filesystems of the specified type. More than one type may be specified in a
comma separated list. The list of filesystem types can be prefixed with ``no'' to specify the filesystem types for which action
should not be taken. For example, the umount command:
umount -a -t nfs,hfs
umounts all filesystems of the type NFS and HFS.
-v Verbose, additional information is printed out as each filesystem is unmounted.
NOTES
Due to the complex and interwoven nature of Mac OS X, umount may fail often. It is recommended that diskutil(1) (as in, ``diskutil unmount
/mnt'') be used instead.

A umount command appeared in Version 6 AT&T UNIX.
