Cannot remove mount option "discard" on an ext4 file system

  • 772

I try to turn off "discard" on an ext4 file system but I cannot succeed.
I tried to add "nodiscard" option in /etc/fstab but I can still see this:

# tune2fs -l /dev/md2|grep disca
Default mount options:    journal_data_writeback user_xattr acl discard
