Hello Sathya, If you are experiencing GFS2 withdraws you may be running into a bug , filesystem corruption, or both. If you have a Red Hat support contract I suggest opening a support case with Red Hat as soon as possible. When you open the support case you'll want to attach sosreports from all nodes (run the sosreport command on every node in the cluster and attach the resultant tarballs to the support case.) If you've hit a withdraw you are likely to keep hitting them and data loss or corruption is a tangible possibility; Red Hat support can help identify the source of the issue and provide relief. If you don't have a Red Hat support contract then please reply to the thread with the kernel versions you are running on all nodes and the full withdraw message and call traces from the messages logs on the affected cluster. You'll be able to identify the withdraw easily in the logs. We'll want the withdraw messages which will include a pointer to the position in code where the error occurred and the nature of the withdraw. We'll also need the stack trace that follows the withdraw as it will allow us to understand the code path involved.
