Amanda::Changer::disk

NAME

DESCRIPTION

This changer operates within a root directory, specified in the changer string, which it arranges as follows:

  $dir -|
        |- drive0/ -|
        |           | data -> '../slot4'
        |- drive1/ -|
        |           | data -> '../slot1'
        |- current -> slot5
        |- slot1/
        |- slot2/
        |- ...
        |- slot$n/

The user should create the desired number slot$n subdirectories, and the changer will take care of dynamically creating the drives as needed, and track the ``current'' slot using the eponymous symlink.

Drives are dynamically allocated as Amanda applications request access to particular slots. Each drive is represented as a subdirectory containing a 'data' symlink pointing to the ``loaded'' slot.

TODO

 - better locking (at least to work on a shared filesystem, if not NFS)
 - manpage
