.TH METAROOT 1M "Mar 26, 2006"
.SH NAME
metaroot \- setup system files for root (/) metadevice
.SH SYNOPSIS
.LP
.nf
\fB/usr/sbin/metaroot\fR \fB-h\fR
.fi
.LP
.nf
\fB/usr/sbin/metaroot\fR [\fB-n\fR] [\fB-k\fR \fIsystem-name\fR] [\fB-v\fR \fIvfstab-name\fR]
[\fB-c\fR \fImddb.cf-name\fR] [\fB-m\fR \fImd.conf-name\fR] [\fB-R\fR \fIroot-path\fR] \fIdevice\fR
.fi
.SH DESCRIPTION
.sp
.LP
The \fBmetaroot\fR command edits the \fB/etc/vfstab\fR and \fB/etc/system\fR
files so that the system may be booted with the root file system (\fB/\fR) on
an appropriate metadevice. The only metadevices that support the root file
system are a stripe with only a single slice or a mirror on a single-slice
stripe.
.sp
.LP
If necessary, the \fBmetaroot\fR command can reset a system that has been
configured to boot the root file system (\fB/\fR) on a metadevice so that it
uses a physical slice.
.SH OPTIONS
.sp
.LP
Root privileges are required for all of the following options except \fB-h\fR.
.sp
.LP
The following options are supported:
.sp
.ne 2
.na
\fB\fB-c\fR \fImddb.cf-name\fR\fR
.ad
.RS 19n
Use \fImddb.cf-name\fR instead of the default \fB/etc/lvm/mddb.cf\fR file as a
source of metadevice database locations.
.RE
.sp
.ne 2
.na
\fB\fB-h\fR\fR
.ad
.RS 19n
Display a usage message.
.RE
.sp
.ne 2
.na
\fB\fB-k\fR \fIsystem-name\fR\fR
.ad
.RS 19n
Edit a user-supplied \fIsystem-name\fR instead of the default \fB/etc/system\fR
system configuration information file.
.RE
.sp
.ne 2
.na
\fB\fB-m\fR \fImd.conf-name\fR\fR
.ad
.RS 19n
Edit the configuration file specified by \fImd.conf-name\fR rather than the
default, \fB/kernel/drv/md.conf\fR.
.RE
.sp
.ne 2
.na
\fB\fB-n\fR\fR
.ad
.RS 19n
Print what would be done without actually doing it.
.RE
.sp
.ne 2
.na
\fB\fB-R\fR \fIroot-path\fR\fR
.ad
.RS 19n
When metaroot modifies system files, it accesses them in their relative
location under \fIroot-path\fR.
.sp
The \fB-R\fR option cannot be used in combination with the \fB-c\fR,
\fB-k\fR,\fB-m\fR, or \fB-v\fR options.
.LP
Note -
.sp
.RS 2
The root file system of any non-global zones must not be referenced with the
\fB-R\fR option. Doing so might damage the global zone's file system, might
compromise the security of the global zone, and might damage the non-global
zone's file system. See \fBzones\fR(5).
.RE
.RE
.sp
.ne 2
.na
\fB\fB-v\fR \fIvfstab-name\fR\fR
.ad
.RS 19n
Edit \fIvfstab-name\fR instead of the default \fB/etc/vfstab\fR table of file
system defaults.
.RE
.SH OPERANDS
.sp
.LP
The following operands are supported:
.sp
.ne 2
.na
\fB\fIdevice\fR\fR
.ad
.RS 10n
Specifies either the metadevice or the conventional disk device (slice) used
for the root file system (\fB/\fR).
.RE
.SH EXAMPLES
.LP
\fBExample 1 \fRSpecifying Root File System on Metadevice
.sp
.LP
The following command edits \fB/etc/system\fR and \fB/etc/vfstab\fR to specify
that the root file system is now on metadevice \fBd0\fR.

.sp
.LP
\fBExample 2 \fRSpecifying Root File System on SCSI Disk
.sp
