On AIX, when we unmount a file system and run varyoffvg, then create a snapshot from another server or move the file system to another node in PowerHA before bringing it back, we encounter an issue. After running varyonvg and mounting the file system again, an error appears in the librenms.log, causing LibreNMS to stop collecting data from all file systems. The only way to fix this is to rediscover the node after the error occurs.
Additionally, if the servers are in PowerHA, all file systems remain in the Storage section on both nodes, and rediscovering the node does not resolve the issue.
