Step 2. Directory Creation: Run the following command to a directory to mount the file system.

[root@linuxcnf ~]# mkdir /dbdata [root@linuxcnf ~]#

Step 3. Unmounting File System: Run the following command to unmount the existing /aapdata mount point. Make sure any process is not utilizing the file system.

[root@linuxcnf ~]# umount /appdata/ [root@linuxcnf ~]#

Step 4. LV Renaming: [Optional] Run the following command to rename logical volume name. This step can be skipped if logical volume renaming not require.

Step 4. Mounting File System: Now run the following command to mount the new /dbdata mount point.

[root@linuxcnf ~]# mount /dev/vg_data/lv_dbdata /dbdata/ [root@linuxcnf ~]#

[root@linuxcnf ~]# vi /etc/fstab .................. /dev/mapper/vg_data-lv_data     /dbdata         xfs     defaults        0 0

Step 6. Verify: Run the following command to verify the new mount point is mounted or not:

[root@linuxcnf ~]# df -hT /dbdata/ Filesystem                    Type  Size  Used Avail Use% Mounted on /dev/mapper/vg_data-lv_dbdata xfs   8.0G   33M  8.0G   1% /dbdata [root@linuxcnf ~]#
