Sun Cluster 3.0 U1 系统管理指南

8.3.2.1 示例 - 恢复根 (/) 文件系统 (Solstice DiskSuite)

下面的示例展示从磁带设备 /dev/rmt/0 恢复到节点 phys-schost-1 的根 (/) 文件系统。从群集中的另一节点 phys-schost-2 运行 metaset 命令,以删除节点 phys-schost-1,稍后再将它重新添加到磁盘集 schost-1 中。所有其它命令都是从 phys-schost-1 上运行的。/dev/rdsk/c0t0d0s0 上创建了一个新的引导块,/dev/rdsk/c0t0d0s4 上重建了三个状态数据库复制品。


[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:]
ok boot cdrom -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
# 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 CTL-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
