In oracle, asm alertlog reports a large number of errors Voting file relocation is required in diskgroup

The customer configures the master machine for the asm instance. asm1 runs on Node 2 and asm2 runs on Node 1. After de-config and re-config are executed, the asm alertlog reports a large number of errors:

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
FS space)
 
@ The issue was identified as PST copies.
@ The issue was identified similar to the following bug. Bug 13448206: TOO restart 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 bytes ;
Alter diskgroup GRID undrop disks failed ;
 
@ Also in Bug: 13906539, the workaround was to create other asm dg and relocate temporary OCR/Vote and move back to initially ASM
@ DG.
