Sun Cluster 系統管理指南 (適用於 Solaris 作業系統)

範例—復原複合裝置 (Solstice DiskSuite/Solaris Volume Manager) 上舊的 root (`/`) 檔案系統

以下範例顯示 root (/) 檔案系統復原至節點 phys-schost-1 (從磁帶裝置 /dev/rmt/0)。 metaset 指令是從叢集的其他節點 phys-schost-2 執行，以便先移除而後將節點 phys-schost-1 重新加入 metaset schost-1 中。所有其他指令是由 phys-schost-1 執行。在 /dev/rdsk/c0t0d0s0 上將建立新的啟動區段，並在 /dev/rdsk/c0t0d0s4 上重新建立三個狀態資料庫副本。

[Become superuser on a cluster node with access to the metaset, 
other than the node to be restored.]
[Remove the node from the metaset:]
phys-schost-2# metaset -s schost-1 -f -d -h phys-schost-1
[Replace the failed disk and boot the node:]

從 Solaris CD 啟動節點︰

SPARC︰出現 OpenBoot PROM ok 提示符號時，請鍵入以下指令︰
ok boot cdrom -s

x86︰將 CD 插入系統的 CD 磁碟機，並透過關閉系統、然後關閉電源再開啟電源的方法來啟動系統。在 [目前的啟動參數] 畫面上，鍵入以下指令︰

                      <<< Current Boot Parameters >>>
Boot path: /pci@0,0/pci8086,2545@3/pci8086,1460@1d/pci8086,341a@7,1/
sd@0,0:a
Boot args:

Type  b [file-name] [boot-flags] <ENTER> to boot with options
or    i <ENTER>                          to enter boot interpreter
or    <ENTER>                            to boot with defaults

                  <<< timeout in 5 seconds >>>
Select (b)oot or (i)nterpreter: b -s

[Use format and newfs to recreate partitions and file systems.]
[Mount the root file system on a temporary mount point:]
# mount /dev/dsk/c0t0d0s0 /a
[Restore the root file system:]
# cd /a
# ufsrestore rvf /dev/rmt/0
# rm restoresymtable
[Install a new boot block:]
# /usr/sbin/installboot /usr/platform/`uname \
-i`/lib/fs/ufs/bootblk /dev/rdsk/c0t0d0s0
[Remove the lines in /temp-mountpoint/etc/system file for MDD root information:]
* Begin MDD root info (do not edit)
forceload: misc/md_trans
forceload: misc/md_raid
forceload: misc/md_mirror
forceload: misc/md_hotspares
forceload: misc/md_stripe
forceload: drv/pcipsy
forceload: drv/glm
forceload: drv/sd
rootdev:/pseudo/md@0:0,10,blk
* End MDD root info (do not edit)
[Edit the /temp-mountpoint/etc/vfstabfile]
Example: 
Change from—
/dev/md/dsk/d10   /dev/md/rdsk/d10    /      ufs   1     no       -

Change to—
/dev/dsk/c0t0d0s0 /dev/rdsk/c0t0d0s0  /usr   ufs   1     no       -
[Unmount the temporary file system and check the raw disk device:]
# cd /
# umount /a
# fsck /dev/rdsk/c0t0d0s0
[Reboot in single-user mode:]
# reboot -- "-s"
[Replace the disk ID:]
# scdidadm -R /dev/dsk/c0t0d0
[Recreate state database replicas:]
# metadb -c 3 -af /dev/rdsk/c0t0d0s4
# reboot
Type Control-d to boot into multiuser mode.
[Add the node back to the metaset:]
phys-schost-2# metaset -s schost-1 -a -h phys-schost-1
