oracle中asm alertlog大量報錯Voting file relocation is required in diskgroup

客戶將asm的執行個體配置錯了主機，asm1運行在節點2，asm2運行在節點1，在進行de-config和re-config之後，asm的alertlog大量報錯：

SYMPTOMS:

NOTE: Attempting voting file refresh on diskgroup GRID
NOTE: Voting file relocation is required in diskgroup GRID
NOTE: Attempting voting file relocation on diskgroup GRID
NOTE: Attempting voting file refresh on diskgroup GRID
NOTE: Voting file relocation is required in diskgroup GRID
NOTE: Attempting voting file relocation on diskgroup GRID
NOTE: Attempting voting file refresh on diskgroup GRID
CAUSE:

Because of bug 13609187, voting file was not getting relocated and fill up the ASM alertlog with the above messages (and of course the
FS space)
 
@The issue was identified as PST copies.
@The issue was identified similar to the following bug. Bug 13448206: TOO MANY OCCURRENCES OF NOTE: ATTEMPTING VOTING FILE @REFRESH ON DISKGROUP
@But this patch did not help in this case. The solution is described below.
SOLUTION

The below operation forced the PST to move to all the disks (OCR/Vote DG) and the voting file relocation operation to complet:
alter diskgroup GRID drop disk <disk_name> rebalance power 0;
alter diskgroup GRID undrop disks;
 
@Also in Bug : 13906539, the workaround was to create other ASM DG and relocate temporary OCR/Vote and move back to initially ASM
@DG.
