FILESYSTEM ERRORS
Gabriel Krisman Bertazi is a senior software engineer at Collabora
One fact of life is that file systems fail. Detecting errors over a fleet of servers is tricky since there’s no generic way to monitor different filesystems in the Linux kernel without peeking at dmesg and filtering through thousands of messages of each machine in the fleet. This approach is cumbersome and prone to missing messages in hightraffic situations.
