OpenAFS 1.5.50 (Development branch)
AFS is a distributed filesystem which offers a client-server architecture, transparent data migration abilities, scalability, a single namespace, and integrated ancillary subsystems. License: IBM Public License Changes:
Unicode character set support, improvements in layering and garbage collection in SMB code, substantial documentation updates, a new NSIS installer instead of a VC runtime, fixes for spurious VNOVOL errors with volser and recloned volumes on all platforms, and updated TSM X/Open API support. The Demand Attach fileserver will no longer crash due to accesses during volume cloning. Support was added for updates to OpenSolaris. Linux RPM packaging materials were updated for the 1.5 release series and 2.4 kernels. This release is the recommended production release for all Microsoft Windows environments.Image

VLDB.DB0(5)							AFS File Reference						       VLDB.DB0(5)

NAME

       vldb.DB0, vldb.DBSYS1 - Contain the Volume Location Database and associated log

DESCRIPTION

       The file vldb.DB0 contains the Volume Location Database (VLDB), which tracks the location of all AFS volumes stored on file server machines
       in the cell. The Volume Location (VL) Server (vlserver process) provides information from the database to Cache Managers when they need to
       access AFS data.

       The file vldb.DBSYS1 is a log file in which the VL Server logs each database operation before performing it. When an operation is
       interrupted, the VL Server replays the log to complete the operation.

       Both files are in binary format and reside in the /var/lib/openafs/db directory on each of the cell's database server machines. When the VL
       Server starts or restarts on a given machine, it establishes a connection with its peers and verifies that its copy of the database matches
       the copy on the other database server machines. If not, the VL Servers call on AFS's distributed database technology, Ubik, to distribute
       to all of the machines the copy of the database with the highest version number.

       Always use the commands in the vos suite to administer the VLDB. It is advisable to create an archive copy of the database on a regular
       basis, using a tool such as the UNIX tar command.
