lctl-lcfg_fork \- duplicate and rename filesystem config llog
.SH SYNOPSIS
.SY "lctl lcfg_fork"
.I FSNAME NEWNAME
.YS
.SH DESCRIPTION
.B lcfg_fork
(alias
.BR fork_lcfg )
generates a new Lustre configuration llog for a 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.
