DESCRIPTION

12       The nfsdclnts(8) command parses the content present in
13       /proc/fs/nfsd/clients/ directories. nfsdclnts(8) displays files which
14       are open, locked, delegated by the nfs-client. It also prints useful
15       client information such as hostname, clientID, NFS version mounted by
16       the nfs-client.
17

OPTIONS

19       -t, --type=TYPE
20           Specify the type of file to be displayed. Takes only one TYPE at a
21           time.
22
23           open, lock, deleg, layout, or all
24
25           open: displays the open files by nfs-client(s).
26
27           lock: displays the files locked by nfs-client(s).
28
29           layout: displays the files for which layout is given.
30
31           deleg: displays delegated files information and delegation type.
32
33           all: prints all the above type.
34
35       --clientinfo
36           displays various nfs-client info fields such as version of nfs
37           mounted at nfs-client and clientID.
38
39       --hostname
40           Print hostname of nfs-client instead of ip-address.
41
42       -q, --quiet
43           Hide the header information.
44
45       -v, --verbose
46           Verbose operation, show debug messages.
47
48       -f, --file
49           Instead of processing all client directories under
50           /proc/fs/nfsd/clients, one can provide a specific states file to
51           process. One should make sure that info file resides in the same
52           directory as states file. If the info file is not valid or present
53           the fields would be marked as "N/A".
54
55       -h, --help
56           Print help explaining the command line options.
