HP StorageWorks File System Extender Software user guide 259
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 -h HSMFileSystemMountPoint
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.
