lsmod - shows modules currently loaded and its dependency/size

[root@localhost /]# lsmod
Module                  Size  Used by
ext4                  583541  1
mbcache                14958  1 ext4
jbd2                  102945  1 ext4
binfmt_misc            17468  1
vmw_vsock_vmci_transport    30577  0
vsock                  34855  3 vmw_vsock_vmci_transport
snd_seq_midi           13565  0
snd_seq_midi_event     14899  1 snd_seq_midi
intel_powerclamp       14419  0
coretemp               13444  0


on modern kernel versions the kernel works together with udev

[root@localhost /]# udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

disconnect kernel module
[root@localhost /]# modprobe -r vfat
[root@localhost /]# lsmod | grep vfat

connect kernel module manually
[root@localhost /]# modprobe vfat
[root@localhost /]# lsmod | grep vfat
vfat                   17411  0
fat                    65913  1 vfat

NFS mount add in fstab _netdev instead of default | firewall-cmd --list-all

By OK -
Redhat recommends us to add  _netdev  option for NFS file system in /etc/fstab. So that they can be mounted after starting the networking service. Alternative ways to refer to partitions: Label : LABEL=label Network ID Samba : //server/share NFS : server:/share SSHFS : sshfs#user@server:/share Device : /dev/sdxy (not recommended) Example #1 //192.168.1.134/share_name /mnt/share_name cifs username=server_user,password=server_password,_netdev 0 0 ^ Path to your share ^ Mountpoint ^ Username ^ Password ^ See note A Note A: The  _netdev  options makes sure the mount is only attempted AFTER a network connection has been established. Example #2 10.10.10.1:/vol1/fs1 /data nfs defaults,_netdev 0 0 ============================ [root@localhost ~]# firewall-cmd --list-all public   target: default   icmp-block-inversion: no   interfaces:   sources:   services: dhcpv6-client high-availabi...
