System Administration Commands - Part 3

metarename

- rename metadevice or switch layered metadevice names

Synopsis

/usr/sbin/metarename [-s setname] metadevice1 metadevice2
/usr/sbin/metarename [-s setname] [-f] -x metadevice1 metadevice2
/usr/sbin/metarename -h

Description

There are two ways to use metarename, one with and one without the -x option. The first method (without -x) renames an existing metadevice to a new name. This makes managing the metadevice namespace easier. The metadevice being renamed cannot be mounted or open, nor can the new name already exist. For example, to rename a metadevice that contains a mounted file system, you would first need to unmount the file system.

With the second way to use metarename, using the -x option, metarename switches (exchanges) the names of an existing layered metadevice and one of its subdevices. In Solaris Volume Manager terms, a layered metadevice can be either a mirror or a trans metadevice. The -x option enables you to switch the metadevice names of a mirror and one of its submirrors, or a trans metadevice and its master device.

metarename -x makes it easier to mirror or unmirror an existing stripe or concatenation, and to remove a trans device.

When used to mirror an existing stripe or concatenatation, you must stop access to the device. For example, if the device contains a mounted file system, you must first unmount the file system before doing the rename.

You can also use the metarename -x command to untrans a trans metadevice from an existing device. This applies only to the master device. You cannot remove a logging device with metarename. Before you can rename a trans device, you must detach the logging device. Then you must stop access to the trans metadevice itself.

You cannot rename or switch metadevices that are in an error state or that have subcomponents in an error state, or metadevices actively using a hot spare replacement.

You can only switch metadevices that have a direct child/parent relationship. You could not, for example, directly exchange a stripe in a mirror that is a master device with the trans metadevice.

You must use the -f flag when switching members of a trans metadevice.

Only metadevices can be switched, not slices.

Options

The following options are supported:

-f

Force the switching of trans metadevice members.

-h

Display a help message.

-s setname

Specifies the name of the diskset on which metarename will work. Using the -s option will cause the command to perform its administrative function within the specified diskset. Without this option, the command will perform its function on the local metadevices.

-x

Exchange the metadevice names metadevice1 and metadevice2.

metadevice1

Specifies the metadevice to be renamed or switched.

metadevice2

Specifies the target metadevice name for the rename or switch operation.

Examples

Example 1 Renaming a Metadevice

This example renames a metadevice named d10 to account_records. Note that account_records must not exist for the rename to succeed.

# metarename d10 account_records

Example 2 Creating a Two-Way Mirror

This example creates a two-way mirror from an existing stripe named d1 with a mounted file system, /home2.

# metainit d2 1 1 c13d0s1
# metainit -f d20 -m d1
# umount /home2
# metarename -x d20 d1
# metattach d1 d2
# mount /home2

First, a second concatenation d2, is created. (d1 already exists.) The metainit command creates a one-way mirror, d20, from d1. Next, you umount the file system and switch d1 for d20, making d1 the top-level device (mirror). You attach the second submirror, d2, to create a two-way mirror. Lastly, you remount the file system.

Example 3 Mounting a Mirrored File System on Stripe

This example takes an existing mirror named d1 with a mounted file system, and ends up with the file system mounted on a stripe d1.

# umount /fs2
# metarename -x d1 d20
# metadetach d20 d1
# metaclear -r d20
# mount /fs2

First, you unmount the file system, then switch the mirror d1 and its submirror d20. This makes the mirror into d20. Next, you detach d1 from d20, then delete the mirror d20 and its other submirror. You then remount the file system.

Example 4 Deleting a Trans Metadevice

This example deletes a trans metadevice named d10 while its mount point is /myhome. The master device, which is a stripe, is named d2. The logging device, also a stripe, is named d5.

# umount /myhome
# metadetach d10
# metarename -f -x d10 d2
# metaclear d2
# metaclear d5
# fsck /dev/md/dsk/d10
# mount /myhome

You umount the file system first, then detach the trans metadevice's logging device. The trans metadevice is switched with the master device, making the trans metadevice d2 and the underlying stripe d10. You clear the trans metadevice d2 and the logging device d5. d10 must be fsck'd, and then the file system is remounted.

Solaris Volume Manager Administration Guide

LIMITATIONS

Renaming and exchanging metadevice names can only be used for metadevices. A physical slice cannot be renamed to a metadevice, nor can a metadevice be exchanged with a physical slice name.

Metadevice names are strings of the pattern d<xyz> where xyz is a value between 0 and 8192. You cannot use logical names for metadevices.

Notes

Trans metadevices have been replaced by UFS logging. Existing trans devices are not logging--they pass data directly through to the underlying device. See mount_ufs(1M) for more information about UFS logging.
