OpenAFS 1.5.57 (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:
afs_config.exe on Windows was fixed. In Linux, a race during file truncation has been corrected. Linux 2.6.29 and MacOS 10.3 (fixed) and OpenBSD 4.4 are supported. The code was fixed to compile on newer OpenSolaris versions. On all client platforms, the userspace AFS library now supports large files when supported by the platform. Reconnection with Disconnected AFS works in more circumstances. On all server platforms, Salvager no longer attempts to recreate headers in the wrong partition. Volumes are properly marked in use on creation. On all platforms, the documentation was updated, and further race conditions in Rx were corrected. 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.
