Manual Rebalance during ASM disk drop operation (Doc ID 1912225.1)

Last updated on OCTOBER 03, 2016

Applies to:

Oracle Database - Enterprise Edition - Version 10.2.0.4 and later
Information in this document applies to any platform.

Symptoms

Need to replace FRA disk to increase the capacity of the disk group .FRA diskgroup is created as EXTERNAL redundancy.

During the rebalance operation  the 2nd node of the cluster went down and  the entries in v$asm_operation were gone immediately

SQL> alter diskgroup fra drop disk 'FRA1' add disk 'ORCL:FRA3';

 
From ASM alert log:

When the server restarted,v$asm_disk shows that :
 SQL> select mount_status, header_status,state,library from v$asm_disk where name = 'FRA1';

MOUNT_S HEADER_STATU STATE    LIBRARY
------- ------------ -------- ----------------------------------------------------------------
CACHED  MEMBER       DROPPING ASM Library - Generic Linux, version 2.0.4 (KABI_V2) ===========>State is dropping


That’s where it left just when the instance went down.

Any attempt to run again "drop disk" command will fail, as expected, since the disk is in DROPPING state

SQL> alter diskgroup fra drop disk 'fra1';
alter diskgroup fra drop disk 'fra1'
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15071: ASM disk "FRA1" is already being dropped
