如何创建具有 ZFS 根文件系统和区域根的 ZFS BE（最低 Solaris 10 5/09）

执行最低 Solaris 10 5/09 发行版的初始安装之后，使用此过程创建 ZFS 根文件系统。使用 luupgrade 功能将 ZFS 根文件系统升级到最低 Solaris 10 5/09 发行版之后，也可以使用此过程。然后，可以升级或修补使用此过程创建的 ZFS BE。

在后面的步骤中，Oracle Solaris 10 9/10 示例系统在 /rpool/zones 中具有 ZFS 根文件系统和区域根数据集。将创建名为 zfs2BE 的 ZFS BE，然后可以对其进行升级或修补。

1. 查看现有的 ZFS 文件系统。

   # zfs list NAME USED AVAIL REFER MOUNTPOINT rpool 7.26G 59.7G 98K /rpool rpool/ROOT 4.64G 59.7G 21K legacy rpool/ROOT/zfsBE 4.64G 59.7G 4.64G / rpool/dump 1.00G 59.7G 1.00G - rpool/export 44K 59.7G 23K /export rpool/export/home 21K 59.7G 21K /export/home rpool/swap 1G 60.7G 16K - rpool/zones 633M 59.7G 633M /rpool/zones

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 2 zfszone running /rpool/zones native shared

3. 创建 ZFS BE。

   # lucreate -n zfs2BE Analyzing system configuration. No name for current boot environment. INFORMATION: The current boot environment is not named - assigning name <zfsBE>. Current boot environment is named <zfsBE>. Creating initial configuration for primary boot environment <zfsBE>. The device </dev/dsk/c1t0d0s0> is not a root device for any boot environment; cannot get BE ID. PBE configuration successful: PBE name <zfsBE> PBE Boot Device </dev/dsk/c1t0d0s0>. 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>. Population of boot environment <zfs2BE> successful. Creation of boot environment <zfs2BE> successful.

4. 激活 ZFS BE。

   # 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>. . . . # init 6

5. 确认在新 BE 中创建了 ZFS 文件系统和区域。

   # zfs list NAME USED AVAIL REFER MOUNTPOINT rpool 7.38G 59.6G 98K /rpool rpool/ROOT 4.72G 59.6G 21K legacy rpool/ROOT/zfs2BE 4.72G 59.6G 4.64G / rpool/ROOT/zfs2BE@zfs2BE 74.0M - 4.64G - rpool/ROOT/zfsBE 5.45M 59.6G 4.64G /.alt.zfsBE 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 17.2M 59.6G 633M /rpool/zones rpool/zones-zfsBE 653M 59.6G 633M /rpool/zones-zfsBE rpool/zones-zfsBE@zfs2BE 19.9M - 633M - # zoneadm list -cv ID NAME STATUS PATH BRAND IP 0 global running / native shared - zfszone installed /rpool/zones native shared
