Thehmdfs.ko file cannot be inserted, and the error "insmod: ERROR: could not insert module hmdfs.ko: Invalid parameters" is reported.

Cause: The kernel used for compiling hmdfs is different from that in the current environment.

Solution 1: Compile ahmdfs.ko file that matches the kernel of the current environment, and then insert the.ko file.

Solution 2: Use an openEuler version that has the same kernel as openEuler 22.03 LTS SP3.

In the openEuler 22.03 LTS SP3 Raspberry Pi version, thehmdfs.ko file cannot be inserted and the error "insmod: ERROR: could not insert module hmdfs.ko: Invalid module format" is reported.

Cause: The Raspberry Pi version uses a special kernel. However, the hmdfs software in the repository is built using the kernel of the openEuler 22.03 LTS SP3 server version. Therefore, the.ko file cannot be inserted.

Solution: Usehmdfs.ko compiled on openEuler 22.03 LTS SP3 raspberry-pi kernel.

The softbus_server service fails to be started, and the error message "GetNetworkIfIp ifName:eth0 fail" is displayed.

Cause: Run the ip a command to view the name of the NIC in the current system and check whether the wired NICeth0 exists. The softbus_server service obtains information such as the IP address through the wired NICeth0. Ifeth0 does not exist, softbus_server cannot be started.

Solution 1: Change the NIC name toeth0.

Solution 2: Modify the softbus_server source code and change the name of the dependent wired NIC to that of the NIC in the current system.

After the softbus_server service is started on multiple openEuler devices, the distributed_file_daemon service logs show that no online device is found.

Cause: The network between devices is disconnected, or the firewall blocks DSoftBus data.

Solution: Check whether the network is normal. (You can runsystemctl stop firewalld.service to temporarily disable the firewall and test the network if services will not be affected.)
