5. Solving problems

I've seen this chapter. VirtOn This is a summary of the major errors and disruptions that can occur in use, and how to quickly identify them by function.

5.1 Common verification procedure

In order.	Check the item	How to take action
1	Login session	When session expires or a message of unauthorization appears, it logs back in.
2	Proxmox API Connecting	[Set it up Proxmox API Check the endpoints and health checks in the connection settings.
3	User permissions and Pool	When the function button is not visible or the execution is restricted, check the role permissions and pool allocation range.
4	Node/cluster status is up.	It's on the dashboard and cluster screen to check the status of the node online and the quorum status.
5	Storage/network status	VM/CT It's about creating, backing up, templates, migrating, and verifying the target storage and network configuration.
6	Logs and workloads	Change settings, control tasks, failures events, and logs of alerts/thank you. Proxmox I check the results from the workforce.

5.2 Functional problem solving location

Function	Detailed location	Main check items
Login/set up	4.1 Login and initial settings	Account locks, IP blocks, session expiration, Proxmox API Early reactions
The dashboard.	4.2 dashboard	API Connection, node/quorum/storage status, scope of permissions
Host Shell	4.3 shell	Access to the shell, Proxmox Password, WebSocket connection
Instances	4.4 instances	VM/CT Failure to create, failure to connect to the console, failure to backup/snapshot
Cluster of people.	4.5 clusters	Cluster creation/genesis failure, network overhaul
Ceph	4.6 Ceph	Health_WARN/ERR, OSD Down, PG state, Monitor/Manager state
HA	4.7 Cost-effectiveness	HA Resources Additional Failure, Restart/Reallocation Policy, Affinity Rules
Template/Migration	4.8 Template/Migration	Failure to upload/download, failure to copy, failure to migrate
We have a resource.	4.9 resource	Failure of resource inspection, delay in graph renewal, specific node failure
Storage.	4.10 storage.	Directory/LVM/NFS/SMB/iSCSI Failed to create, Failed to delete
The network.	4.11 Network	Bridge/VLAN/Bond creation failed, connection failure after application of change
Alert/Thanks log	4.12 Warning	Security alert scope, audit log access permissions, log delayed log
Set it up	4.13 Set	API Failed to save, account/limit/pool setup, self-test, SMTP transmission failure

5.3 Controller notified

Type of warning	How to check
A screen warning.	Check the alert menu at the top right and the alert at the bottom right.
List of security warnings	[Check the security alerts list on the page for account locks, IP blocks, system alerts.
Thank you, Log.	ADMIN Or SUPER ADMIN You can access the audit log with your account to verify the actors, the access IP, the subject, the results.
Email notification is in order.	If the SMTP settings and user email settings are complete, check whether the test mail and the actual security event mail are received.
