LVM HOWTO
Logical volume management provides a higher-level view of the disk storage on a computer system than the traditional view of disks and partitions. This gives the system administrator much more flexibility in allocating storage to applications and users. Storage volumes created under the control of the logical volume manager can be resized and moved around almost at will, although this may need some upgrading of file system tools. The logical volume manager also allows management of storage volumes in user-defined groups, allowing the system administrator to deal with sensibly named volume groups such as "development" and "sales" rather than physical disk names such as "sda" and "sdb". One of the difficult decisions facing a new user installing Linux for the first time is how to partition the disk drive. With logical volume management, the whole disk would be allocated to a single volume group and logical volumes created to hold the / /usr and /home file systems. His options are not good:

Examples: Grant read access (r) to a file to all members of your group (g): chmod g+r file-name Grant read access to a directory to all members your group: chmod g+rx directory-name Note that "execute" permission is required in order to read a directory. View file, directory and device permissions: Permissions may be viewed by issuing the command: ls -l file-name File can be written by youself and members of the group. Format:
