Difference between df -Th and lsblk












0














I am wondering why the output of df -Th and lsblk commands showing different mount points for logical volume tmp.



[root@mysystem ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VOLGROUP-root 23G 7.6G 14G 37% /
devtmpfs 16G 0 16G 0% /dev
tmpfs 16G 88K 16G 1% /dev/shm
tmpfs 16G 217M 16G 2% /run
tmpfs 16G 0 16G 0% /sys/fs/cgroup
/dev/sda1 488M 103M 350M 23% /boot
/dev/mapper/VOLGROUP-tmp 9.8G 107M 9.1G 2% /tmp
/dev/mapper/VOLGROUP-var 20G 1000M 18G 6% /var
/dev/mapper/VOLGROUP-home 4.8G 27M 4.6G 1% /home
/dev/mapper/VOLGROUP-lv_var_log 7.8G 83M 7.3G 2% /var/log


And



[root@mysystem ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 62G 0 disk
├─sda1 8:1 0 512M 0 part /boot
├─sda2 8:2 0 4G 0 part [SWAP]
└─sda3 8:3 0 57.5G 0 part
├─VOLGROUP-root 253:0 0 22.5G 0 lvm /
├─VOLGROUP-tmp 253:1 0 10G 0 lvm /var/tmp
├─VOLGROUP-var 253:2 0 20G 0 lvm /var
└─VOLGROUP-home 253:3 0 5G 0 lvm /home
sdb 8:16 0 8G 0 disk
└─sdb1 8:17 0 8G 0 part
└─VOLGROUP-lv_var_log 253:4 0 8G 0 lvm /var/log
sdc 8:32 0 100G 0 disk
sr0 11:0 1 1024M 0 rom


However for all other lv, mount points are same for both the commands. Or is there any difference in Mounted on and MOUNTPOINT?
