ALM-12015 Device Partition File System Read-Only (For MRS 2.x or Earlier)

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).

Procedure

Go to the MRS cluster details page and choose Alarms.
In the real-time alarm list, click the row that contains the alarm.
In the Alarm Details area, obtain HostName and PartitionName from Location. HostName indicates the node for which the alarm is generated, and PartitionName indicates the partition of the faulty disk.
Contact hardware engineers to check whether the disk is faulty. If the disk is faulty, remove it from the server.
After the disk is removed, the system reports ALM-12014 Partition Lost. Handle the alarm by following the instructions in ALM-12014 Device Partition Lost (For MRS 2.x or Earlier). After the handling, the alarm is automatically cleared.
