Re-organize mount/umount, so that you do not always forget to come to the new machine.

Attaching is to add the separated File System to the file system partition structure. The file system must be appended to a mount point, that is, a directory.
Mounting and detaching a file system occurs when the system starts and closes.
The/etc/vfstab file will be read when the system starts. The file system to be mounted. Therefore, the file system in the/etc/vfstab file will be automatically mounted. You can also manually mount the file system in the command line mode.

Mount without parameters displays the mounted file system.

1. the mount option. You can use-o to calibrate the mount option.

The nolargefiles parameter will make all new files in the file system smaller than 2 GB bytes.
Remount indicates to mount that it should be reloaded to a file system that has been loaded. This is usually used to change the loading mark of a file system. It can be used to change a read-only file system to a readable file system.
Ro loads the file system as read-only
Rw loads the file system into a readable/writable file system.
Intr allows killing processes waiting in the file system.

# Mount-o nolargefiles/dev/dsk/c0t3d0s7/export/home

The file size in the file system cannot exceed 2 GB. This parameter may cause errors because the file system contains files larger than 2 GB. Note: yes under/dev/dsk/instead of/dev/rdsk,
Because the devices under/dev/rdsk are physical devices and files under/dev/dsk are connected to/dev/rdsk

To mount an existing file system in/etc/vfstab, you only need to use the command
# Mount/export/home

# Mount-a notifies mount of all file systems to be loaded, equivalent to/usr/sbin/mountall
It is usually not used by administrators but automatically issued by/etc/init. d/MOUNTFSYS at system startup.

Umount unmount the File System
# Umount/dev/dsk/c0t3d0s7
Or
# Umount/export/home
If a file in the file system is in use, the file system cannot be detached.

When a device is in the busy status
Available
# Umount-f/mount_point force Uninstall a directory (easy to lose data)
Or use the following: (recommended)

Using the fuser Command
To stop all processes from accessinga file system:
As root, list all the processes accessing the file system
# Fuser-cu mount_point
2. Kill all processes accessing the file system.
# Fuser-ck mount_point
3. Verify there are no processes accessing the file system.
# Fuser-c mount_point
4. Unmount the file system.
# Umount mount_point
