excerpt from 'man mount';
-v Verbose mode.
-a Mount all filesystems (of the given types) mentioned in fstab.
-l Add the ext2, ext3 and XFS labels in the mount output. Mount
must have permission to read the disk device (e.g. be suid root)
for this to work. One can set such a label for ext2 or ext3
using the e2label(8) utility, or for XFS using xfs_admin(8), or
for reiserfs using reiserfstune(8).
You can always 'man command' to get full information to allow a better understanding of the usage.
If you look at the '-a' option you will see that the mount should use the static information from the 'fstab'.
The '-v' is just a verbose so as to get information from the actions.
The '-l' is for label use.
If you take the information from the command line and the output that you received. You did not have a '-a' specification for the the device that you were trying to mount via the 'fstab'. Plus no label definition.
If I were mounting a 'ext' filesystem then the 'mount /dev/some_device /mnt/some_mount_point' would default to the 'ext' filesystem since one was not specified. Now if that file was a 'NTFS' then I would use 'mount -t ntfs-3g /dev/some_NTFS_device /mnt/some_mount_point'. The 'ntfs-3g' file type would be used to allow R/W of the filesystem.
You should 'man mount' to understand a little more.
