转 Oracle 10G RAC下OCR和Voting disk的管理
[size=2]Voting disk(表决磁盘方面): [/size]Voting disk记录节点成员信息，如包含哪些节点成员、节点的添加删除信息记录，大小为20MB 查看voting disk位置：crsctl query css votedisk $ crsctl query css votedisk 0. 0 /dev/rhdisk3 如果CRS安装过程失败,需要重新安装则需要初始化voting disk盘,可用DD或重建卷 dd if=/dev/zero of=/dev/rhdisk3 bs=8192 count=2560 备份votedisk: dd if=/dev/rhdisk3 of=/tmp/votedisk.bak 恢复votedisk: dd if=/tmp/votedisk.bak of=/dev/rhdisk3 添加voting disk镜像盘: crsctl add css votedisk /d

On SUSE Linux Enterprise Server 10, because the older Linux threads API has been removed from GLIBC, setting this parameter causes the SRVCTL and VIPCA utilities to exit with the following error:/opt/oracle/crs/jdk/jre/bin/java: error while loading shared libraries: libpthread.so
