如何升级或修补具有区域根的 ZFS 根文件系统（最低 Solaris 10 5/09）

在 Solaris 10 5/09 或以上的发行版中，当您需要升级或修补具有区域根的 ZFS 根文件系统时，请使用此过程。这些更新可以是对系统进行升级，也可以是应用一些修补程序。

在后面的步骤中，zfs2BE 为升级或修补的引导环境的示例名称。

1. 查看现有的 ZFS 文件系统。

   # zfs list NAME USED AVAIL REFER MOUNTPOINT rpool 7.38G 59.6G 100K /rpool rpool/ROOT 4.72G 59.6G 21K legacy rpool/ROOT/zfs2BE 4.72G 59.6G 4.64G / rpool/ROOT/zfs2BE@zfs2BE 75.0M - 4.64G - rpool/ROOT/zfsBE 5.46M 59.6G 4.64G / rpool/dump 1.00G 59.6G 1.00G - rpool/export 44K 59.6G 23K /export rpool/export/home 21K 59.6G 21K /export/home rpool/swap 1G 60.6G 16K - rpool/zones 22.9M 59.6G 637M /rpool/zones rpool/zones-zfsBE 653M 59.6G 633M /rpool/zones-zfsBE rpool/zones-zfsBE@zfs2BE 20.0M - 633M -

2. 确保安装和引导了区域。

   # zoneadm list -cv ID NAME STATUS PATH BRAND IP 0 global running / native shared 5 zfszone running /rpool/zones native shared

3. 创建 ZFS BE 以进行升级或修补。

   # lucreate -n zfs2BE Analyzing system configuration. Comparing source boot environment <zfsBE> file systems with the file system(s) you specified for the new boot environment. Determining which file systems should be in the new boot environment. Updating boot environment description database on all BEs. Updating system configuration files. Creating configuration for boot environment <zfs2BE>. Source boot environment is <zfsBE>. Creating boot environment <zfs2BE>. Cloning file systems from boot environment <zfsBE> to create boot environment <zfs2BE>. Creating snapshot for <rpool/ROOT/zfsBE> on <rpool/ROOT/zfsBE@zfs2BE>. Creating clone for <rpool/ROOT/zfsBE@zfs2BE> on <rpool/ROOT/zfs2BE>. Setting canmount=noauto for </> in zone <global> on <rpool/ROOT/zfs2BE>. Creating snapshot for <rpool/zones> on <rpool/zones@zfs10092BE>. Creating clone for <rpool/zones@zfs2BE> on <rpool/zones-zfs2BE>. Population of boot environment <zfs2BE> successful. Creation of boot environment <zfs2BE> successful.

4. 选择以下操作之一来升级系统或将修补程序应用到新引导环境：

   • 升级系统。

     # luupgrade -u -n zfs2BE -s /net/install/export/s10up/latest

     其中 -s 选项指定 Solaris 安装介质的位置。

     此过程要花费很长时间。

     有关 luupgrade 过程的完整示例，请参见示例 5–6。

   • 将修补程序应用到新引导环境。

     # luupgrade -t -n zfs2BE -t -s /patchdir patch-id-02 patch-id-04

5. 激活新引导环境。

   # lustatus Boot Environment Is Active Active Can Copy Name Complete Now On Reboot Delete Status -------------------------- -------- ------ --------- ------ ---------- zfsBE yes yes yes no - zfs2BE yes no no yes - # luactivate zfs2BE A Live Upgrade Sync operation will be performed on startup of boot environment <zfs2BE>. . . .

6. 从新激活的引导环境引导。

   # init 6

示例 5–6 将具有区域根的 ZFS 根文件系统升级到 Oracle Solaris 10 9/10 ZFS 根文件系统

在此示例中，将在具有 ZFS 根文件系统和非根池的区域根的 Solaris 10 10/09 系统上创建的 ZFS BE (zfsBE) 升级到 Oracle Solaris 10 9/10 发行版。此过程要花费较长时间。然后，激活升级的 BE (zfs2BE)。请确保在尝试升级之前，安装并引导了区域。

在此示例中，zonepool 池、/zonepool/zones 数据集和 zfszone 区域是按如下方式创建的：

# zpool create zonepool mirror c2t1d0 c2t5d0
# zfs create zonepool/zones
# chmod 700 zonepool/zones
# zonecfg -z zfszone
zfszone: No such zone configured
Use 'create' to begin configuring a new zone.
zonecfg:zfszone> create
zonecfg:zfszone> set zonepath=/zonepool/zones
zonecfg:zfszone> verify
zonecfg:zfszone> exit
# zoneadm -z zfszone install
cannot create ZFS dataset zonepool/zones: dataset already exists
