It is not necessary to run -this daemon on machines that are not acting as NFSv4 servers. -.PP -When a network partition is combined with a server reboot, there are -edge conditions that can cause the server to grant lock reclaims when -other clients have taken conflicting locks in the interim. A more detailed -explanation of this issue is described in \s-1RFC\s0 3530, section 8.6.3. -.PP -In order to prevent these problems, the server must track a small amount -of per-client information on stable storage. This daemon provides the -userspace piece of that functionality. -.SH "OPTIONS" -.IX Header "OPTIONS" -.IP "\fB\-d\fR, \fB\-\-debug\fR" 4 -.IX Item "-d, --debug" -Enable debug level logging. -.IP "\fB\-F\fR, \fB\-\-foreground\fR" 4 -.IX Item "-F, --foreground" -Runs the daemon in the foreground and prints all output to stderr -.IP "\fB\-p\fR \fIpipe\fR, \fB\-\-pipe\fR=\fIpipe\fR" 4 -.IX Item "-p pipe, --pipe=pipe" -Location of the \*(L"cld\*(R" upcall pipe. The default value is -\&\fI/var/lib/nfs/rpc_pipefs/nfsd/cld\fR. If the pipe does not exist when the -daemon starts then it will wait for it to be created. -.IP "\fB\-s\fR \fIstorage_dir\fR, \fB\-\-storagedir\fR=\fIstorage_dir\fR" 4 -.IX Item "-s storagedir, --storagedir=storage_dir" -Directory where stable storage information should be kept. The default -value is \fI/var/lib/nfs/nfsdcld\fR. -.SH "NOTES" -.IX Header "NOTES" -The Linux kernel NFSv4 server has historically tracked this information -on stable storage by manipulating information on the filesystem -directly, in the directory to which \fI/proc/fs/nfsd/nfsv4recoverydir\fR -points. -.PP -This daemon requires a kernel that supports the nfsdcld upcall. If the -kernel does not support the new upcall, or is using the legacy client -name tracking code then it will not create the pipe that nfsdcld uses to -talk to the kernel. -.PP -This daemon should be run as root, as the pipe that it uses to communicate -with the kernel is only accessable by root. The daemon however does drop all -superuser capabilities after starting. Because of this, the \fIstoragedir\fR -should be owned by root, and be readable and writable by owner. -.SH "AUTHORS" -.IX Header "AUTHORS" -The nfsdcld daemon was developed by Jeff Layton .
