When you create a Logical volume , you need to add it into /etc/fstab file for it to stay as mounted when server reboot.
suppose you have create a logical volume like bellow
lvdisplay --- Logical volume --- LV Name /dev/POSREP-DB/DB VG Name POSREP-DB LV UUID 0IEKZw-tEoI-jJWt-OGXT-F0B7-hEic-hCbteW LV Write Access read/write LV Status available # open 1 LV Size 1.17 GB Current LE 300 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:2
now you’ll need to set the label for this directory with the following command:
# e2label /dev/POSREP-DB/DB DB
Now add this one into /etc/fstab
LABEL=DB /DB ext3 defaults 0 1
at last, create a directory with bellow command
now if you reboot the server , the logical volument will be mounted automatically in /DB directory.
