die Seilerwerks

Hello folks. Just a note to let you know that, on the heels of Google’s recent Google Apps integrations, I’ve decided to go back to blogger and make my life a bit simpler.

A few months ago, we had a test instance complaining that it couldn’t write to ASM. This was an 11.1.0.7 single (non-RAC) instance on Oracle Enterprise Linux 5, using ASM for the storage. We first saw these errors in the alert log:

ORA-15032: not all alterations performed
ORA-29702: error occurred in Cluster Group Service operation
ORA-29702: error occurred in Cluster Group Service operation
ERROR: error ORA-15032 caught in ASM I/O path

Uh-oh, that doesn’t look good. So I log into the ASM instance and try to see if the disks are OK:

SQL> select path, mount_status from v$asm_disk;
select path, mount_status from v$asm_disk
                               *
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-29702: error occurred in Cluster Group Service operation
