Re: [Bacula-users] LTO-5 Tapes full after between 30-130gb Dell PV-124T

2013-01-16 Thread lst_hoe02 

Zitat von bdoran bill.do...@concordia.ca:

 Hi,

 I'm using a Bacula setup in conjunction with a Dell PV-124T which  
 has 16 LTO-5 tapes. The system works correctly except that the tapes  
 become extremely quickly. There is no consistency between the amount  
 written to each tape though it is generally in the range of 30-130gb  
 - far less then the expected volume.

Check if you are really using LTO-5 media. Test with a known working  
tape loaded. Bacula simply writes to tape until the tape-drive reports  
a write error, this is used as tape-full marker.

Regards

Andreas

Why do you have commented out Maximum Spool Size? And I could not find
any Spool Data directive.

In case of LTO-5, I'm not currently sure about the needed minimal tape
write speed, but you should expect it somewhere among 40-70 MB/s, and
it is almost impossible to do it without data spooling.

[Bacula-users] LTO-5 Tapes full after between 30-130gb Dell PV-124T

2013-01-15 Thread bdoran 
Hi,

I'm using a Bacula setup in conjunction with a Dell PV-124T which has 16 LTO-5 
tapes. The system works correctly except that the tapes become extremely 
quickly. There is no consistency between the amount written to each tape though 
it is generally in the range of 30-130gb - far less then the expected volume.

I'm not getting an error messages in either dmesg or kern.log, there are no 
errors when swapping between tapes bacula simply gets back a -1 from the tape 
drive:


bacula-sd End of Volume Tape13 at 3:8729 on device LTO5-Drive1 (/dev/nst0). 
Write of 1048576 bytes got -1.

bacula-sd Re-read of last block succeeded.

My dir:

Pool {
  Name = LTO5
  Pool Type = Backup
  Recycle = yes   # Bacula can automatically recycle Volumes
  AutoPrune = yes # Prune expired volumes
  Volume Retention = 45 days  # one year
}

Storage {
  Name = LTO5
  Address = localhost# N.B. Use a fully qualified name here
  SDPort = 9103
  Password = password
  Device = PV-124T
  Media Type = LTO5
  Autochanger = Yes
}

Client {
  Name = bacula-fd-local
  Address = localhost
  FDPort = 9102
  Catalog = MyCatalog
  Password = password  # password for FileDaemon
  File Retention = 45 days# 30 days
  Job Retention = 6 months# six months
  AutoPrune = yes # Prune expired Jobs/Files
}
JobDefs {
  Name = DefaultJob
  Type = Backup
  Level = Incremental
  Client = bacula-fd-local
  Messages = Standard
  Pool = LTO5
  Priority = 10
  Write Bootstrap = /var/lib/bacula/%c.bsr
}
Job {
  Name = HeritageJob
  JobDefs = DefaultJob
  FileSet = HeritageSet
  Schedule = WeeklyCycle2
  Storage=LTO5
}

My sd:

Storage { # definition of myself
  Name = bacula-sd
  SDPort = 9103  # Director's port
  WorkingDirectory = /var/lib/bacula
  Pid Directory = /var/run/bacula
  Maximum Concurrent Jobs = 20
  SDAddress = 127.0.0.1
}

Device {
 Name = LTO5-Drive1
 Drive Index = 0
 Media Type = LTO5
 Device Type = Tape
 Archive Device = /dev/nst0
 Changer Device = /dev/sg4
 AutomaticMount = yes;   # when device opened, read it
 AlwaysOpen = yes;
 RemovableMedia = yes;
 RandomAccess = no;
 AutoChanger = yes;
 Maximum File Size = 10G
 #Maximum Spool Size = 50G
 #Maximum Job Spool Size = 20G # will need this is there are concurrent jobs
 Maximum Block Size = 1024k
 Spool Directory = /home/bacula/tapehold

 Alert Command = sh -c 'tapeinfo -f %c |grep TapeAlert|cat'
   }

Autochanger {
Name = PV-124T
Device = LTO5-Drive1
Changer Command = /etc/bacula/scripts/mtx-changer %c %o %S %a %d
Changer Device = /dev/sg4
}

If anyone could suggest any possible routes to a solution or perhaps mistakes 
I've made in config I would greatly appreciate it.

Thanks,

Bill
