Given that the /data filesystem (located on device /dev/sdc1) is using the ext4 filesystem and is corrupted, the best command to address the issue is:
fsck /dev/sdc1
This command runs a filesystem check and repair on the /dev/sdc1 partition, which is mounted at /data.
Important: Before running fsck, ensure the partition is unmounted to avoid further corruption:
umount /data
fsck /dev/sdc1

rmmod is a trivial program to remove a module (when module unloading support is provided) from the kernel. Most users will want to use modprobe(8) with the -r option instead.

The firewall-cmd --list-services command will return the results for which the administrator is looking. This command will list all services that are allowed through the firewall in the default zone or a specified zone. A service is a predefined set of ports and protocols that can be enabled or disabled by firewalld. The firewall-cmd --get-services command will list all available services that are supported by firewalld, not only those that are allowed through the firewall. The firewall-cmd -- check-config command will check if firewalld configuration files are valid, not list services. The systemct1 status firewalld command will display information about the firewalld service unit, such as its state, PID, memory usage, and logs, not list services.
