NAME
nfsdclnts - print various nfs client information for knfsd
server.
SYNOPSIS
nfsdclnts [-h] [-t type] [--clientinfo] [--hostname] [-q]
DESCRIPTION
The nfsdclnts(8) command parses the content present in
/proc/fs/nfsd/clients/ directories. nfsdclnts(8) displays files
which are open, locked, delegated by the nfs-client. It also
prints useful client information such as hostname, clientID, NFS
version mounted by the nfs-client.
OPTIONS
-t, --type=TYPE
Specify the type of file to be displayed. Takes only one TYPE
at a time.
open, lock, deleg, layout, or all
open: displays the open files by nfs-client(s).
lock: displays the files locked by nfs-client(s).
layout: displays the files for which layout is given.
deleg: displays delegated files information and delegation
type.
all: prints all the above type.
--clientinfo
displays various nfs-client info fields such as version of
nfs mounted at nfs-client and clientID.
--hostname
Print hostname of nfs-client instead of ip-address.
-q, --quiet
Hide the header information.
-v, --verbose
Verbose operation, show debug messages.
-f, --file
Instead of processing all client directories under
/proc/fs/nfsd/clients, one can provide a specific states file
to process. One should make sure that info file resides in
the same directory as states file. If the info file is not
valid or present the fields would be marked as "N/A".
-h, --help
Print help explaining the command line options.
