Wait for the recovery to complete (monitor via v$asm_operation ). Once done, the health checker will automatically clear the failure and log a corresponding "failure cleared" message.
: In "Normal" or "High" redundancy groups, the failure of a disk or a whole failure group can trigger this checker.
The ASM Health Checker runs continuously within the background processes of an ASM instance (specifically managed by components like the and Global Enqueue Service (LMON) ).
Verify physical hardware or multipathing configurations to ensure the device path (e.g., /dev/sdg1 ) is still visible to the OS. asm health checker found 1 new failures updated
Do not panic. A "new failure" is an alert, not necessarily a catastrophe. Follow these steps to determine the severity: 1.1 Check the Alert Log
When your ASM instance registers a failure, use this sequence of administrative tasks to evaluate and fix the problem. 1. Locate the Relevant Trace Files
This command checks the consistency of the metadata directory for the specified disk group, performing checks on all disks in that group. If an inconsistency is found, you’ll get a detailed error message in the alert log indicating the nature of the problem. Wait for the recovery to complete (monitor via
Update your UDEV rules file if permissions reset after a reboot. Reload UDEV triggers using udevadm trigger . Clear the Health Checker Alert
In the world of database administration, "1 new failure" is rarely just a number; it’s a riddle. She logged into the terminal, the cursor blinking like a nervous heartbeat. As she ran the diagnostic tool, the system confirmed the dread: was reporting a predictive failure on a single member.
A physical disk has failed, and its status is OFFLINE or MISSING . The ASM Health Checker runs continuously within the
The message is a crucial early warning system. It signifies that your storage layer has lost resilience, even if the database is currently online. Because ASM relies on redundancy to protect data, a "new failure" effectively puts the system in a degraded state.
The coffee hadn’t even finished brewing when Sarah saw the notification on her primary dashboard:
