Oracle Solaris ZFS 管理指南

使用 Oracle Solaris Live Upgrade 迁移到 ZFS 根文件系统（没有区域）

以下示例说明如何将 UFS 根文件系统迁移到 ZFS 根文件系统。

如果要迁移或更新具有区域的系统，请参见以下各节：

示例 5–3 使用 Oracle Solaris Live Upgrade 将 UFS 根文件系统迁移到 ZFS 根文件系统

以下示例说明如何从 UFS 根文件系统创建 ZFS 根文件系统的 BE。包含 UFS 根文件系统的当前 BE ufsBE 由 -c 选项标识。如果不包括可选的 -c 选项，则当前 BE 名称将缺省为设备名称。新 BE zfsBE 由 -n 选项标识。在执行 lucreate 操作之前，ZFS 存储池必须存在。

必须使用片而不是整个磁盘创建 ZFS 存储池，才能使 ZFS 存储池可升级和可引导。创建新池之前，请确保要用于池中的磁盘具有 SMI (VTOC) 标签而不是 EFI 标签。如果使用 SMI 标签重新标记磁盘，请确保标记过程未更改分区方案。在大多数情况下，所有磁盘容量应位于打算用于根池的片中。

# lucreate -c ufsBE -n zfsBE -p rpool

lucreate 操作完成后，使用 lustatus 命令查看 BE 状态。例如：


# lustatus
Boot Environment           Is       Active Active    Can    Copy      
Name                       Complete Now    On Reboot Delete Status    
-------------------------- -------- ------ --------- ------ ----------
ufsBE                      yes      yes    yes       no     -         
zfsBE                      yes      no     no        yes    -

然后，查看 ZFS 组件列表。例如：


# zfs list
NAME                   USED  AVAIL  REFER  MOUNTPOINT
rpool                 7.17G  59.8G  95.5K  /rpool
rpool/ROOT            4.66G  59.8G    21K  /rpool/ROOT
rpool/ROOT/zfsBE      4.66G  59.8G  4.66G  /
rpool/dump               2G  61.8G    16K  -
rpool/swap             517M  60.3G    16K  -

接下来，使用 luactivate 命令激活新 ZFS BE。例如： 


# luactivate zfsBE
A Live Upgrade Sync operation will be performed on startup of boot environment <zfsBE>.

**********************************************************************

The target boot environment has been activated. It will be used when you 
reboot. NOTE: You MUST NOT USE the reboot, halt, or uadmin commands. You 
MUST USE either the init or the shutdown command when you reboot. If you 
do not use either init or shutdown, the system will not boot using the 
target BE.

**********************************************************************

Modifying boot archive service
Activation of boot environment <zfsBE> successful.

接下来，将系统重新引导至 ZFS BE。


# init 6

确认 ZFS BE 是否处于活动状态。


# lustatus
Boot Environment           Is       Active Active    Can    Copy      
Name                       Complete Now    On Reboot Delete Status    
-------------------------- -------- ------ --------- ------ ----------
ufsBE                      yes      no     no        yes    -         
zfsBE                      yes      yes    yes       no     -

如果切换回 UFS BE，必须重新导入在引导 ZFS BE 时创建的所有 ZFS 存储池，因为它们在 UFS BE 中不会自动可用。

如果不再需要 UFS BE，可以使用 ludelete 命令将其删除。

示例 5–4 使用 Oracle Solaris Live Upgrade 从 ZFS BE 中创建 ZFS BE

在同一池中从 ZFS BE 创建 ZFS BE 非常快捷，因为该操作使用 ZFS 快照和克隆功能。如果当前 BE 驻留在同一 ZFS 池上，则可以省略 -p 选项。

如果有多个 ZFS BE，请执行以下操作来选择从哪个 BE 引导：

示例 5–5 升级 ZFS BE (luupgrade)

您可以使用其他软件包或修补程序升级 ZFS BE。

基本过程如下：
