I know mount and df lists all mounts. But I would like to list the mounts which failed to establish on boot, too. How do I get them?

You can use df command to list mount points. You can use -t followed by filesystem type (say ext3, ext4, nfs) to display respective mount points. For examples below df command display all NFS mount points.
To see the list of mounted filesystems, type the simple “findmnt” command in the shell as below, which will list all the filesystems in a tree-type format. This snapshot contains all the necessary details about the filesystem; its type, source, and many more.
The mount command mounts a storage device or filesystem, making it accessible and attaching it to an existing directory structure. The umount command "unmounts" a mounted filesystem, informing the system to complete any pending read or write operations, and safely detaching it.
Use the lsfs command to display information about mount points, permissions, file system size and so on. Important: For file systems to be NFS exported, be sure to verify that logical volume names for these file systems are consistent throughout the cluster.
The definitive list of mounted filesystems is in /proc/mounts. If you have any form of containers on your system, /proc/mounts only lists the filesystems that are in your present container. For example, in a chroot, /proc/mounts lists only the filesystems whose mount point is within the chroot.
How to list all the mount points in Linux? Listing all the mount points for partitions in Linux is very straightforward using the mount command via the terminal. You must be root or sudo to root in order to run this command.
If you have any form of containers on your system, /proc/mounts only lists the filesystems that are in your present container. For example, in a chroot, /proc/mounts lists only the filesystems whose mount point is within the chroot.
How To Show Mounted Devices In Linux Operating System. To list the mounted devices in Linux system, you can use any one of the following command to see mounted devices under Linux Operating System. 1. df command – It show file system disk space usage. 2. mount command – It show all mounted file systems.
There is no such command, since there is no list of "attempted mounts". You can compare the current mount list (/etc/mtab) to the list of shares registered to be mounted though (/etc/fstab).
Alternatively you could try to grep through the system log files to find failed mount attempts.

You can use mount -a to mount all the mount points defined in the fstab.
If there is some kind of error mounting, you will get some warning. If the mount point is already mounted successfully, the command will do nothing with that mountpoint.
Mount errors should appear in dmesg.
