Hi List
I have had some fairly regular job failures that I have pinpointed to be
caused by tape status type error mismatches. The most common is that the
tape status does not match that of the catalogue in a number of ways.
The first is that if the catalogue reports the volume status to be
error, used or full and I manually change the status of the volume using
*update -> Volume parameters -> Volume status -> Pool -> PoolName -> Append
How can I be sure that the volume/tape has been updated as well as the
catalogue?
How can I read the status of a volume/tape without referring to the
catalogue, to see the true tape status?
The second mismatch issue involves the catalogue reporting a different
file count than the volume actually contains, this is a typical error:
27-Feb 23:05 backup-sd JobId 514: Error: Bacula cannot write on tape
Volume "Wednesday1" because:
The number of files mismatch! Volume=103 Catalog=0
How can I avoid an error like this halting a job?
The third mismatch is reported by the status of the storage daemon by
user intervention. Often when I manually unmount a volume the storage
daemon reports back the the device is BLOCKED due to user intervention.
I'm not 100% sure but this error the causes a job to fail, even when I
use a script to automatically umount then mount just before the job starts.
Is there a way to eliminate old BLOCKED messages so they do not prevent
a legitimate job?
Here is a cut down copy of my bacula-dir.conf
Director {
Name = backup-dir
DIRport = 9101
QueryFile = "/etc/bacula/query.sql"
WorkingDirectory = "/var/bacula/working"
PidDirectory = "/var/run"
Maximum Concurrent Jobs = 1
Password = "******"
Messages = Daemon
}
Job {
Name = "holly"
Type = Backup
Level = Full Client = holly
FileSet = "holly"
Storage = LTO-2
Pool = Default
RunBeforeJob = "/etc/bacula/scripts/runbefore.sh"
Write Bootstrap = "/var/lib/bacula/holly.bsr"
Schedule = "WeeklyCycle"
Messages = Standard
Priority = 7
Max Start Delay = 22h
Max Run Time = 30m
}
FileSet {

Include {

File = /export/home/dir
}
Exclude {
}
}
Client {
Name = holly
Address = holly
FDPort = 9102
Catalog = MyCatalog
Password = "*****" # password for FileDaemon
File Retention = 30 days # 30 days
Job Retention = 6 months # six months
AutoPrune = yes # Prune expired Jobs/Files
}
Pool {
Name = Wednesday
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 6 days }
