-.SH DESCRIPTION
-.TP
-.B fork_lcfg \fR{fsname} {newname}
-Generate Lustre configuration for the given filesystem
-.I newname
-based on the specified Lustre system
-.I fsname
-configuration. It is not simply copy. Instead, it uses the
-.I newname
-as the filesystem name in the new configuration. It can be used to
-backup the system configuration, or generate configuration for the
-snapshot that has the same configuration as the original filesystem
-but with different filesystem names.
-
-.TP
-.B erase_lcfg \fR{fsname}
-Permanently erase configuration for the named filesystem. It can be
-used to remove the backup configuration or delete inactive filesystem
-(or snapshot) from a shared MGS.

+lctl\-lcfg_clear \- clear filesystem config llog
+.SH SYNOPSIS
+.br
+.B lctl lcfg_clear \fIFSNAME\fR|\fIDEVNAME
+.br
+.SH DESCRIPTION
+.B lcfg_clear
+(alias
+.BR clear_conf )
+is run on the MGS node, with the MGS device mounted with the
+.B -o nosvc
+flag. It cleans up any records marked
+.I SKIP
+from the configuration files stored in the
+.I CONFIGS/
+directory. If
+.I DEVNAME
+is given, then the specific logs for
+that filesystem (e.g.
+.IR testfs-MDT0000 )
+are processed. Otherwise, if a filesystem name is given, then all
+configuration files are cleared. The previous configuration log is
+backed up on the MGS disk with the suffix
+.IR 'config.timestamp.bak' ,
+such as
+.IR 'testfs-MDT0000.1476454535.bak' .

+.SH NAME
+lctl-lcfg_fork \- duplicate and rename filesystem config llog
+.SH SYNOPSIS
+.IR "\fBlctl lcfg_fork" " <" FSNAME "> <" NEWNAME >
+.SH DESCRIPTION
+.B lcfg_fork
+(alias
+.BR fork_lcfg )
+generates a new Lustre configuration llog for the filesystem named
+.I NEWNAME
+based on the existing Lustre filesystem configuration for
+.IR FSNAME .
+It is not simply a copy of
+.I FSNAME
+to new configuration files named
+.IR NEWNAME ,
+but rather it also replaces all instances of
+.I FSNAME
+in the configuration with
+.I NEWNAME
+as the filesystem name. It can be used to
+backup the system configuration, or generate configuration for the
+snapshot that has the same configuration as the original filesystem
+but with different filesystem names.
