barriers does not help you much or are implicit because you
have no physical disk under the FS and the underlying storage
should have battery backed buffers and doe snot need to confirm
the physical write to the disk to have the data safe

/dev/sdd1 on /storage type ext4 (rw,noexec,noatime,nodiratime,commit=45,inode_readahead_blks=64)
Default mount options: journal_data_writeback nobarrier
