Writing to a General-Purpose File System Failed

Symptom

Data failed to be written to the general-purpose file system mounted to ECSs running the same type of OS.

Possible Causes

The ECS security group configuration is incorrect. Specifically, the port used to communicate with the general-purpose file system is not enabled.

Fault Diagnosis

Check whether the port of the ECS is enabled and correctly configure the port on the security group console.

Solution

1. Log in to the ECS console.
2. Select the target ECS and go to its details page.
3. Click the Security Groups tab and select the target security group. Click Manage Rule to go to the security group console.
4. On the displayed page, click the Inbound Rules tab and click Add Rule to open the Add Inbound Rule page, as shown in Figure 1. Add rules as follows:

   You need to add inbound and outbound rules for the security group. For details, see Adding a Security Group Rule. The inbound ports required by NFS are ports 111, 2049, and 2050.
