Mon, 01 Jan 0001 00:00:00 +0000

This section describes how to view the CSI version.

Procedure

Use a remote access tool, such as PuTTY, to log in to any master node in the Kubernetes cluster through the management IP address.

Run the following command to query information about the node where huawei-csi-node resides.

kubectl get pod -A -owide | grep huawei-csi-node

The following is an example of the command output.

NAMESPACE NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
huawei-csi huawei-csi-node-87mss 3/3 Running 0 6m41s 192.168.129.155 node-1 <none> <none>
huawei-csi huawei-csi-node-xp8cc 3/3 Running 0 6m41s 192.168.129.156 node-2 <none> <none

Use a remote access tool, such as PuTTY, to log in to any node where huawei-csi-node resides through the node IP address.

Performing Check Before Collection

Use a remote access tool, such as PuTTY, to log in to the node where the oceanctl tool is installed in the Kubernetes cluster through the management IP address.
Run the following command. The displayed version is v4.11.0.
```
oceanctl version
```
The following is an example of the command output.
```
Oceanctl Version: v4.11.0
```

Run the oceanctl collect logs –help command. The following information is displayed.

$ oceanctl collect logs --help
Collect logs of one or more nodes in specified namespace in Kubernetes

Usage:
 oceanctl collect logs [flags]

Examples:
 # Collect logs of all nodes in specified namespace
 oceanctl collect logs -n <namespace>

 # Collect logs of specified node in specified namespace
 oceanctl collect logs -n <namespace> -N <node>

 # Collect logs of all nodes in specified namespace
 oceanctl collect logs -n <namespace> -a

 # Collect logs of all nodes in specified namespace with a maximum of 50 nodes collected at the same time
 oceanctl collect logs -n <namespace> -a --threads-max=50

 # Collect logs of specified node in specified namespace
 oceanctl collect logs -n <namespace> -N <node> -a

Flags:
 -a, --all Collect all nodes messages
 -h, --help help for logs
 -n, --namespace string namespace of resources
 -N, --nodename string Specify the node for which information is to be collected.
 --threads-max int set maximum number[1~1000] of threads for nodes to be collected. (default 50)

Global Flags:
 --log-dir string Specify the directory for printing log files. (default "/var/log/huawei")

Run the following command to check whether a Pod is started properly. In the command, huawei-csi indicates the namespace for installing CSI.
