Postgres Data Encryption Using LUKS with dm-crypt

We have encrypted volume using LUKS.

*cryptsetup luksOpen /root/test1 volume1*
and mounted on

*mount /dev/mapper/volume1 /mnt/files*
We created postgres data directory inside /mnt/files and able to start the
postgres database.

*/usr/local/pgsql/bin/pg_ctl -D /mnt/files/postgres/ -l
/var/logs/postgres/postgrs.log start*
Even though we unmounted /mnt/files

*sudo umount -l /mnt/files*
When we try to close volume using LUKS.

*sudo cryptsetup luksClose volume1*
Getting following errors:

*device-mapper: remove ioctl on volume1 failed: Device or resource busy*
