Hi! This is my first post and im not that familiar with UNIX but I'll try to explain my problem..
I have a server here at work running Open UNIX Release 8.0.0
It has a special application on it that I'm trying to run a database backup on. For the last 2 weeks this has failed.. Usually the backup takes 1 hour to run but now it failes after 8 hours (often have to reboot the machine in the morning for the users to be able to access the application again)
I have the backup log that i can attach but its very large.. And im not sure it will say anything...
I have some CPU and Disk activity output for you.. But my question is basicly is there some way i can see what is happening.. What the system is trying to write where? To find out why it failes?
The backup has been running for 1h 45min as i write this and it have some heavy disk activity on the c0b0t0d0s1 "slice?" all the time.. Is this /dev/root partition/slice?

BACKUP_DBVERIFY(8) AFS Command Reference BACKUP_DBVERIFY(8)NAME
backup_dbverify - Checks the integrity of the Backup Database
SYNOPSIS
backup dbverify [-detail] [-localauth]
[-cell <cell name>]
[-help]
backup db [-d] [-l] [-c <cell name>] [-h]
DESCRIPTION
The backup dbverify command checks the integrity of the Backup Database. The command's output indicates whether the Backup Database is
damaged (data is corrupted) or not. If the Backup Database is undamaged, it is safe to continue using it. If it is corrupted, discontinue
any backup operations until it is repaired.
CAUTIONS
While this command runs, no other backup operation can access the Backup Database; the other commands do not run until this command
completes. Avoid issuing this command when other backup operations are likely to run. The backup savedb command repairs some types of
corruption.
OPTIONS-detail
Reports the number of orphaned blocks found, any inconsistencies, and the name of the server machine running the Backup Server that is
checking its copy of the database.
-localauth
Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The backup command interpreter presents it to
the Backup Server, Volume Server and VL Server during mutual authentication. Do not combine this flag with the -cell argument. For more
details, see backup(8).
-cell <cell name>
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see backup(8).
-help
Prints the online help for this command. All other valid options are ignored.
OUTPUT
The command displays one of the following two messages:
Database OK
The database is undamaged and can be used.
Database not OK
The database is damaged. You can use the backup savedb command to repair many kinds of corruption as it creates a backup copy. For
more detailed instructions, see the OpenAFS Administration Guide chapter about performing backup operations.
The -detail flag provides additional information:
o The number of orphan blocks found. These are ranges of memory that the Backup Server preallocated in the database but cannot use.
Orphan blocks do not interfere with database access, but do waste disk space. To free the unusable space, dump the database to tape by
using the backup savedb command, and then restore it by using the backup restoredb command.
o Any inconsistencies in the database, such as invalid hostnames for Tape Coordinator machines.
o The name of the database server machine on which the Backup Database was checked, designated as the "Database checker". For a detailed
trace of the verification operation, see the /var/log/openafs/BackupLog file on the indicated machine. You can use the bos getlog
command to display it.
EXAMPLES
The following command confirms that the Backup Database is undamaged:
% backup dbverify
Database OK
The following command confirms that the Backup Database is undamaged and that it has no orphan blocks or invalid Tape Coordinator entries.
The Backup Server running on the machine "db1.abc.com" checked its copy of the Database.
% backup dbverify -detail
Database OK
Orphan blocks 0
Database checker was db1.abc.com
PRIVILEGE REQUIRED
The issuer must be listed in the /etc/openafs/server/UserList file on every machine where the Backup Server is running, or must be logged
onto a server machine as the local superuser "root" if the -localauth flag is included.
