Thank you very much, it seems the "async" does not display if you succeed to
mount.
root#mount /dev/sda1 /mnt/sda1 -o remount,rw,noatime,sync
/dev/sda1 on /mnt/sda1 type fuseblk
(rw,noatime,sync,user_id=0,group_id=0,allow_other,blksize=4096)
root#mount /dev/sda1 /mnt/sda1 -o remount,rw,noatime,async
/dev/sda1 on /mnt/sda1 type fuseblk
(rw,noatime,user_id=0,group_id=0,allow_other,blksize=4096)

Works here on RHEL 7.2:
socbl648:/root# mount -o rw,noatime,sync /dev/sdc /mnt
socbl648:/root# mount | grep /mnt
/dev/sdc on /mnt type vfat
(rw,noatime,sync,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro)
^^^^
socbl648:/root# mount -o rw,noatime,async /dev/sdc /mnt
socbl648:/root# mount | grep /mnt
/dev/sdc on /mnt type vfat
(rw,noatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro)
(no sync)
Please post your output from using sync and async, e.g. with the shell
command.
HTH,
Luep Christoph
