Description

The system checks the partition status every 60 seconds. This alarm is generated when the system detects that a partition to which service directories are mounted is lost (because the device is removed or goes offline, or the partition is deleted). The system checks the partition status periodically.

This alarm must be manually cleared.

Impact on the System

Possible Causes

The hard disk is removed.
The hard disk is offline, or a bad sector exists on the hard disk.

Procedure

On FusionInsight Manager, click O&M > Alarm > Alarms, and click in the row where the alarm is located.
Obtain HostName, PartitionName and DirName from Location.
Check whether the disk of PartitionName on HostName is inserted to the correct server slot.
- If yes, go to 4.
- If no, go to 5.
Contact hardware engineers to remove the faulty disk.
Log in to the HostName node where an alarm is reported and check whether there is a line containing DirName in the /etc/fstab file as user root.
- If yes, go to 6.
- If no, go to 7.
Run the vi /etc/fstab command to edit the file and delete the line containing DirName.
Contact hardware engineers to insert a new disk. For details, see the hardware product document of the relevant model. If the faulty disk is in a RAID group, configure the RAID group. For details, see the configuration methods of the relevant RAID controller card.
Wait 20 to 30 minutes (The disk size determines the waiting time), and run the mount command to check whether the disk has been mounted to the DirName directory.
- If yes, manually clear the alarm. No further operation is required.
- If no, go to 9.
