MP-RAS file size limitations
Hello,

Here is the question. We have 2 identical boxes (see below), one is functioning as production second is being built as backup. Backup was
built by 'osa' restore (image taken from production). Problem is..the max filesize on production is 2147481600 bytes and the max filesize on backup
is 6144 bytes smaller at 2147475456 (yes..the max filesize on this OS is 2 gig). How can two images of one box be different ? Where can I find out how to check/set the filesize (thinking there is an inconsistency btwn the two boxes)?

Thanks in advance,,,I am primarily a DBA and need help figuring this out.

NCR MP-RAS v3.2 UNIX (32bit OS) on NCR3520 (DellT410) 64bit 4 core 8 CPU Pentium Pro.

to clarify further the smaller filesize limit (6 mb) on the backup is preventing critical
replication tasks that move large files over from production

bdb.db0

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

NAME

       bdb.DB0, bdb.DBSYS1 - Contain the Backup Database and associated log

DESCRIPTION

       The bdb.DB0 file contains the Backup Database, which records configuration information used by the AFS Backup System along with cross-
       indexed records of the tapes created and volumes dumped using the Backup System commands.

       The bdb.DBSYS1 file is a log file in which the Backup Server (buserver process) logs each database operation before performing it. When an
       operation is interrupted, the Backup 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 database server machine that runs the Backup
       Server.	When the Backup Server starts or restarts on a given machine, it establishes a connection with its peers and verifies that its
       copy of the bdb.DB0 file matches the copy on the other database server machines. If not, the Backup Servers use AFS's distributed database
       technology, Ubik, to distribute to all of the machines the copy of the database with the highest version number.

       Use the commands in the backup suite to administer the Backup Database. It is advisable to create a backup copy of the bdb.DB0 file on tape
       on a regular basis, using the UNIX tar command or another local disk backup utility.
