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?

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)

fuser
FUSER(1) BSD General Commands Manual FUSER(1)NAME
fuser -- list IDs of all processes that have one or more files open
SYNOPSIS
fuser [-cfkmu] [-M core] [-N system] [-s signal] file ...
DESCRIPTION
The fuser utility writes to stdout the PIDs of processes that have one or more named files open. For block and character special devices,
all processes using files on that device are listed. A file is considered open by a process if it was explicitly opened, is the working
directory, root directory, jail root directory, active executable text, kernel trace file or the controlling terminal of the process. If -m
option is specified, the fuser utility will also look through mmapped files.
The following options are available:
-c Treat files as mount point and report on any files open in the file system.
-f The report must be only for named files.
-k Send signal to reported processes (SIGKILL by default).
-m Search through mmapped files too.
-u Write the user name associated with each process to stderr.
-M Extract values associated with the name list from the specified core instead of the default /dev/kmem.
-N Extract the name list from the specified system instead of the default, which is the kernel image the system has booted from.
-s Use given signal name instead of default SIGKILL.
The following symbols, written to stderr will indicate how files is used:
r The file is the root directory of the process.
c The file is the current workdir directory of the process.
j The file is the jail-root of the process.
t The file is the kernel tracing file for the process.
x The file is executable text of the process.
y The process use this file as its controlling tty.
m The file is mmapped.
w The file is open for writing.
a The file is open as append only (O_APPEND was specified).
d The process bypasses fs cache while writing to this file (O_DIRECT was specified).
s Shared lock is hold.
e Exclusive lock is hold.
EXIT STATUS
The fuser utility returns 0 on successful completion and >0 otherwise.
EXAMPLES
The command: ``fuser -fu .'' writes to standard output the process IDs of processes that are using the current directory and writes to stderr
an indication of how those processes are using the directory and user names associated with the processes that are using this directory.
SEE ALSO fstat(1), ps(1), systat(1), iostat(8), pstat(8), vmstat(8)STANDARDS
The fuser utility is expected to conform to IEEE Std 1003.1-2004 (``POSIX.1'').
HISTORY
The fuser utility appeared in FreeBSD 9.0.
AUTHORS
The fuser utility and this manual page was written by Stanislav Sedov <stas@FreeBSD.org>.
BUGS
Since fuser takes a snapshot of the system, it is only correct for a very short period of time. When working via kvm(3) interface the report
will be limited to filesystems the fuser utility knows about (currently only cd9660, devfs, nfs, ntfs, nwfs, udf, ufs and zfs).
