Description

Free space on an HSM file system runs out and the following error is written to the kernel ring

 

buffer (displayed by the dmesg command):

 

[CRITICAL] FSE-HSM not listening for FS events! Unmount FS and check FSE logs for more

 

details!

 

(Linux system specific)

Explanation

n/a

Workaround

To solve this critical situation, proceed as follows:

 

1.

Check free space on the HSM file system. Invoke the following command:

 

 

df -hHSMFileSystemMountPoint

 

1.

Stop the FSE implementation:

 

 

fse --stop

 

2.

Extend the size of the volume that stores the HSM file system. Use the lvextend command

 

 

for this purpose.

 

3.

Reconfigure the corresponding FSE partition with modified values for the

 

 

CriticalWatermark, HighWaterMark, and ReleaseInterval variables to prevent

 

 

the HSM file system from becoming full.

 

4.

Start the FSE implementation:

 

 

fse --start

 

5.

To identify potential inconsistencies, run the following command on the FSE partition

 

 

containing the HSM file system which became full:

fsecheck --fsc-hsmfs PartitionName

Description

If the I/O traffic on an HSM file system is very high, the Hierarchical Storage Manager (HSM)

 

process may stop reading file system events and completely block access to the HSM file

 

system.

 

(Linux system specific)

Explanation

n/a

Workaround

Terminate all user applications that are currently trying to access the HSM file system, including

 

NFS and Samba daemons.
