SYNOPSIS

DESCRIPTION

13       statd  is  an  intermediate version of the status monitor. It interacts
14       with lockd(1M) to provide the crash  and  recovery  functions  for  the
15       locking  services  on  NFS.  statd keeps track of the clients with pro‐
16       cesses which hold locks on a server. When the server  reboots  after  a
17       crash,  statd  sends  a  message to the statd on each client indicating
18       that the server has rebooted. The client statd  processes  then  inform
19       the  lockd on the client that the server has rebooted. The client lockd
20       then attempts to reclaim the lock(s) from the server.
21
22
23       statd on the client host also informs the statd on the server(s)  hold‐
24       ing  locks  for  the client when the client has rebooted. In this case,
25       the statd on the server informs its lockd that all locks  held  by  the
26       rebooting  client  should be released, allowing other processes to lock
27       those files.
28
29
30       lockd is started by automountd(1M), mount_nfs(1M), and share(1M) if NFS
31       automounts are needed.

NOTES

76       The crash of a server is only detected upon its recovery.
77
78
79       The statd service  is  managed  by  the  service  management  facility,
80       smf(5), under the service identifier:
81
82         svc:/network/nfs/status
83
84
85
86
87       Administrative actions on this service, such as enabling, disabling, or
88       requesting restart, can be performed using  svcadm(1M).  The  service's
89       status can be queried using the svcs(1) command.
90
91
92       If  it is disabled, it will be enabled by mount_nfs(1M), share_nfs(1M),
93       and automountd(1M) unless  its        application/auto_enable  property
94       is set to false.
