I have a LVM volume named /dev/mapper/centos-root, centos being the volume group, root being a logical volume.
It has the fstab entry below
/dev/mapper/centos-root / xfs defaults 0 0

I have created two mount points to store tomcat data
mkdir -p /opt/tcsserver
mkdir -p /sys_data/tcsserver

when i mount these 2 mountpoints to lvm and gave mount|grep /dev/mapper/centos-root

mount /dev/mapper/centos-root /opt/tcsserver
mount /dev/mapper/centos-root /sys_data/tcsserver
mount -a
mount|grep /dev/mapper/centos-root

it shows the mountpoint perfectlty

can i have this added permanently like this below?
/dev/mapper/centos-root / xfs defaults 0 0
/dev/mapper/centos-root /opt/tcsserver xfs defaults 0 0
/dev/mapper/centos-root /sys_data/tcsserver xfs defaults 0 0

Will the above entry /etc/fstab work?
If i reboot will it come up?

          You seem to have /dev/mapper/centos-root mapped to three different mount points— which I’m pretty sure doesn’t work.

          But, if you mount /dev/mapper/centos-root to /, then /opt/tcsserver and /sys_data/tcsserver should also be part of that partition (unless you have something else mounted at /opt or /sys_data)— so you don’t have to and shouldn’t mount it three times.

          In short, no. But just mounting your volume to / should be fine if you want everything on the same drive.

          If what you want is to have /opt/tcsserver and /sys_data/tcsserver be the same, you can use a symlink:
          sudo ln -s /opt/tcsserver /sys_data/tcsserver
