Issue Cannot access Plesk Control Panel 12.5 (504 Gateway Time-out nginx)

[m3lezZ]

Hi 3lezZ

• Now all sites back to normal.
• I can also access to Plesk Admin

Do I need to perform

#plesk repair all -y

Again?

No that should be all, if you have any further questions, let me know.

Hi 3lezZ

Thank you very for bear with me and help me out as well as Igor.
Could please also (if possible) explain what SharedLockManagerStorage* has to do with this problem?

Thank you again

Lock management is a common cluster-infrastructure service that provides a mechanism for other cluster infrastructure components to synchronize their access to shared resources. In a Red Hat Enterprise Linux cluster, DLM (Distributed Lock Manager) is the lock manager.

A lock manager is a traffic cop who controls access to resources in the cluster, such as access to a GFS file system. You need it because without a lock manager, there would be no control over access to your shared storage, and the nodes in the cluster would corrupt each other's data.

As implied in its name, DLM is a distributed lock manager and runs in each cluster node; lock management is distributed across all nodes in the cluster. GFS2 and CLVM use locks from the lock manager. GFS2 uses locks from the lock manager to synchronize access to file system metadata (on shared storage). CLVM uses locks from the lock manager to synchronize updates to LVM volumes and volume groups (also on shared storage). In addition, rgmanager uses DLM to synchronize service states.
