之前RAC環(huán)境出現(xiàn)了故障,節(jié)點2操作系統(tǒng)崩潰,重裝系統(tǒng)后,CRS添加成功,但是CRS啟動有問題,排查發(fā)現(xiàn)節(jié)點2 ASM的+DATA diskgroup無法mount,報如下錯誤:
ORA-15063: ASM discovered an insufficient number of disks for diskgroup "DATA"
在ASM實例上檢查磁盤組和磁盤的狀態(tài),發(fā)現(xiàn)+DATA diskgroup的6塊盤有3塊是MEMBER,有3塊是PROVISIONED。
NOMOUNT狀態(tài),導致添加操作失敗,而嘗試在目前正常工作的節(jié)點添加磁盤,結果同樣報錯:
- SQL> alter diskgroup DATA add disk '/dev/oracleasm/disks/OADB_DATA_300G_6';
- alter diskgroup DATA add disk '/dev/oracleasm/disks/OADB_DATA_300G_6'
- *
- ERROR at line 1:
- ORA-15032: not all alterations performed
- ORA-15029: disk '/dev/oracleasm/disks/OADB_DATA_300G_6' is already mounted by this instance
