NFSDCLTS(8) nfsdclnts NFSDCLTS(8)
nfsdclnts - print various nfs client information for knfsd server.
nfsdclnts [-h] [-t type] [--clientinfo] [--hostname] [-q]
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.
-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.

/proc/fs/nfsd/clients/
Displays basic information about each NFSv4 client.

including open modes, device numbers, inode numbers, and open owners.
