ALM-12015 Device Partition File System Read-Only

Updated at: Aug 17, 2021 GMT+08:00

Description

This alarm is generated when the system detects that a partition to which service directories are mounted enters the read-only mode (due to a bad sector or a faulty file system). The system checks the partition status periodically.

This alarm is cleared when the system detects that the partition to which service directories are mounted exits from the read-only mode (because the file system is restored to read/write mode, the device is removed, or the device is formatted).
