need help setting up bareos and dell lto-8

[Savchik Victor]

Hello,
We have a Dell LTO-8 and 1 cartridge.
When setting up a backup, we get that we have 1 Volume that has the status Used. We cannot record further backups on tape.

Configs of our backup.

Client {
  Name = wiki-cl
  Description = "Client resource of the Director itself."
  Address = wiki.example.com
  Password = ""          # password for FileDaemon
  Maximum Concurrent Jobs = 6
}
FileSet {
    Name = "wiki-fs"
    Include {
        Options {
            Signature = MD5
            Compression = LZ4HC
            noatime = yes
            }
        File = "/var/opt/wiki-catalog"
        }
}

Job {
    Name = "wiki-jb"
    Description = "Backup the catalog database (after the nightly save)"
    JobDefs = "wiki-jd"
    Level = Full
    FileSet="wiki-fs"
    Schedule = "wiki-sc"

    Priority = 7
}
Job {
    Name = "wiki-jb"
    Description = "Backup the catalog database (after the nightly save)"
    JobDefs = "wiki-jd"
    Level = Full
    FileSet="wiki-fs"
    Schedule = "wiki-sc"

    Priority = 7
}
JobDefs {
  Name = "wiki-jd"
  Type = Backup
  Level = Full
  Client = wiki-cl
  FileSet = "wiki-fs"                     # selftest fileset                            (#13)
  Schedule = "wiki-sc"
  Storage = wiki-st
  Messages = Standard
  Pool = wiki-pl
  Priority = 12
  Write Bootstrap = "/var/lib/bareos/%c.bsr"
  Full Backup Pool = wiki-pl                 # write Full Backups into "Full" Pool         (#05)
  Differential Backup Pool = Differential  # write Diff Backups into "Differential" Pool (#08)
  Incremental Backup Pool = Incremental    # write Incr Backups into "Incremental" Pool  (#11)
  Allow Mixed Priority = yes
 
}
Pool {
  Name = wiki-pl
  Pool Type = Backup
  Recycle = yes                       # Bareos can automatically recycle Volumes
  AutoPrune = yes                     # Prune expired volumes
  Volume Retention = 5 hours         # How long should the Full Backups be kept? (#06)
  Maximum Volume Jobs = 1
  Maximum Volume Bytes = 200G          # Limit Volume size to something reasonable
  Maximum Volumes = 200               # Limit number of Volumes in Pool
  Label Format = "Full-$Client-$JobId"     # Volumes will be labeled "Full-<volume-id>"
  UseVolumeOnce = yes
  Volume Use Duration = 5 hours
}
Schedule {
  Name = "wiki-sc"
  Run = Full 1-31 at 1:30                   # (#04)
}
Storage {
  Name = wiki-st
  Address = backup.example.com                # N.B. Use a fully qualified name here (do not use "localhost" here).
  Password = ""
  Device = wiki-sd
  Media Type = LTO-8
}
Device {
   Name = wiki-sd
   Media Type = LTO-8
   Archive Device = /dev/nst1
   LabelMedia = yes
   Autochanger = no
   AutomaticMount = yes
   AlwaysOpen = no
}

after one successful backup, we receive the following messages the next time

bareos-sd JobId 85993: Warning: Director wanted Volume "Full-wiki-cl-85877".
Current Volume "Full-wiki-cl-85875" not acceptable because:
1998 Volume "Full-wiki-cl-85875" catalog status is Used, but should be Append, Purged or Recycle.

bareos-sd JobId 85993: Please mount append Volume "Full-wiki-cl-85877" or label a new one for:
Job: wiki-jb.2022-07-20_08.51.54_02
Storage: "wiki-sd" (/dev/nst1)
Pool: wiki-pl
Media type: LTO-8

How to do it correctly so that he continues to write on the tape. Without overwriting the previous Volume?

[Bruno Friedmann]

This is normal you configure it to behave like this

 Maximum Volume Jobs = 1

1 Job = Volume goes to Used.

[Savchik Victor]

by changing the settings to Maximum Volume Jobs = 0 and removing UseVolumeOnce = yes. Bareos is still trying to write a backup to the previous volume and I went back to the error above. What is volume in the Used status

also interested in the question 1 cartridge = 1 volume?

Yes one tape is a volume, a volume can hold many jobs you can list all jobs on a volume with

list jobs volume=volname

I would delete Maximum Volume Jobs completely and leave it the default,

Also then delete the volume and start over. Often (been a while my setup currently works) volumes when labeled get values from the pool and do not update when the pool value changes.

list volumes pool=wiki-pl

Or for more details

llist volume=volname

Should show things like retention values, and they might not match the current pool values. If you start over and relabel the tape you won’t have worries.
