HSM file system filter problems
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] ivd-HSM not listening for FS events! Unmount FS and check OA logs for more details!
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 OA implementation:
ivd --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 OA partition with modified values for the CriticalWatermark, HighWaterMark, and ReleaseInterval variables to prevent the HSM file system from becoming full.
4. Start the OA implementation:
ivd --start
5. To identify potential inconsistencies, run the following command on the OA partition containing the HSM file system which became full:
ivdcheck --fsc-hsmfs PartitionName
