Sun Cluster 系統管理指南 (適用於 Solaris 作業系統)

範例—復原 root (/) 檔案系統 (Solstice DiskSuite/Solaris Volume Manager)

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 phys-schost-2 的另一個節點執行,以便先移除而後將 phys-schost-1 節點重新加入 schost-1 磁碟組中。 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 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︰


[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
# cd /
# umount /a
# fsck /dev/rdsk/c0t0d0s0
[Install a new boot block:]
# /usr/sbin/installboot /usr/platform/`uname \
-i`/lib/fs/ufs/bootblk /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
Press 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
