标题: svm疑难问题
创建了multi-owner组之后，无意中给人重新将磁盘分区label，可能导致ora_data的metadb损坏，现在2个机器都是member，但是没有一个机器可以作为owner
机器是solaris10，装了cluster3.1

在双机情况下的操作：
root@ph2#metaset -s ora_data

Multi-owner Set name = ora_data, Set number = 1, Master = ph1

Host             Owner       Member
  ph1                            Yes
  ph2                            Yes

Driv Dbase

d7 Yes

d8 Yes
root@ph2 # metadb -i
      flags          first blk    block count
   a m  pc luo       16             8192          /dev/dsk/c0t2d0s6
   a pc luo       8208          8192          /dev/dsk/c0t2d0s6
   a pc luo       16400          8192          /dev/dsk/c0t2d0s6
//省略相关说明的输出

root@ph2 # metadb -s ora_data -i
metadb: ph2: ora_data: not owner of metadevice database

root@ph2 # metaset -s ora_data -j
metaset: ph2: ora_data: there are no existing databases

root@ph2 # metaset -s ora_data -t
metaset: -t option not allowed on multi-owner diskset
usage:  metaset -s setname -a [-A enable | disable] -h hostname ...
      metaset -s setname -a [-M] -h hostname ...
      metaset -s setname -a [-M] [-l length] [-L] drivename ...
      metaset -s setname -d [-M] -h hostname ...
      metaset -s setname -d [-M] -f -h all-hostnames
      metaset -s setname -d [-M] [-f] drivename ...
      metaset -s setname -d [-M] [-f] hostname ...
      metaset -s setname -A enable | disable
      metaset -s setname -t [-f]
      metaset -s setname -r
      metaset [-s setname] -j [-M]
      metaset [-s setname] -w [-M]
      metaset -s setname -P [-M]
      metaset -s setname -b [-M]
      metaset -s setname -o [-M] [-h hostname]
      metaset [-s setname]

            hostname = contents of /etc/nodename
            drivename = cNtNdN no slice
            [-M] for multi-owner set is optional except on set creation

1号机上的信息

root@ph1 # metaset -s ora_data

Multi-owner Set name = ora_data, Set number = 1, Master = ph1

Host             Owner       Member
  ph1                            Yes
  ph2                            Yes

Driv Dbase

d7 Yes

d8 Yes

root@ph1 # metadb -s ora_data -i
metadb: ph1: ora_data: not owner of metadevice database

root@ph1 # metaset -s ora_data -j
metaset: ph1: ora_data: there are no existing databases

root@ph1 # metaset -s ora_data -t
metaset: -t option not allowed on multi-owner diskset

root@ph1 # metaset -s ora_data -d -M -f -h ph1
metaset: ph1: ora_data: must be owner of the set for this command

在2个机器都启动到单机之后
root@ph2 # metaimport -rv
metaimport: no unconfigured sets detected

root@ph1 # metadb -s ora_data -a c2t12d0s2
metadb: ph1: ora_data: must be owner of the set for this command

svm可维护性真的很差！咳

手动向d7和d8的slice7上添加metadb行不？
You will have to use the metadb command to remove and add
replicas if you repair a disk containing one (remove broken ones and
add back onto repaired disk).
其实这个问题可以引申到如果共享磁盘组中的硬盘故障后，应该怎么恢复
