Backup Central

Hi there.

I have a very cool Bacula installation on gentoo, backuping on a dell
PV 124T with LTO5 tape.
Everything works ok... almost.

I have no problem backuping and restoring over several volume.

However i get trouble when come the time to recycle tape. Bacula try
to recycle tape, and that's ok with me. But when it tries, i don't
know what's happening but it seems it detroys the tape header (with
the volume name on it).

For instance, a tape name is flagged to be recycled. so far i can read
the tape header using btape /dev/nst0 and:

-- flag as recycle, but not tried yet --
*readlabel
btape: btape.c:528 Volume label read correctly.

Volume Label:
Id : Bacula 1.0 immortal
VerNo : 11
VolName : 000017L5
PrevVolName :
VolFile : 0
LabelType : VOL_LABEL
LabelSize : 164
PoolName : AllIncrementals
MediaType : LTO-5
PoolType : Backup
HostName : gozer
Date label written: 21-Mar-2011 01:29

This tape is FLAGGED, but has not been tried to be reused yet.

Now here is a tape that has been tried to be reuse:

-- flag as recycle and tried to be --
*readlabel
06-Dec 12:07 btape JobId 0: Error: block.c:1002 Read error on fd=3 at
file:blk 0:0 on device "Batman" (/dev/nst0). ERR=Input/output error.
btape: btape.c:525 Volume has no label.

Volume Label:
Id : **error**VerNo : 0
VolName :
PrevVolName :
VolFile : 0
LabelType : Unknown 0
LabelSize : 0
PoolName :
MediaType :
PoolType :
HostName :
Date label written: -4712-01-01 at 00:00
*

Clearly, it seems that my bacula is erasing the label on the tape at
some point, and then is unable to reuse it.

What's wrong with me ?
So far, the only thing i've been able to do was to destroy the volume
completly in the database and create a new one with the same label, as
bacula just don't agree with relabeling a tape with a name which is
already in the DB. This is not really what i think about Automatic
recycling.

Please help me !

Are you using truncate after purge ?
http://www.bacula.org/5.2.x-manuals/en/main/main/New_Features_in_5_0_1.html#SECTION00910000000000000000

Could explain what you see on your tape
Truncate is usefull (if any) for File

Hi Bruno.

Nope, i don't use this option. My bacula version is 5.0.3.

Is ActionOnPurge=Truncate the default behavior ? i have no override
on this, so if it's default, it could be that.

I have several tape that are waiting for rotation because of the "bad
label" tape blocking issue, but the other seems to be not corrupted yet.
I guess, some of those tape should be reuse as well as soon the
situation is solved, but as i don't have any people working those day,
having the whole system blocked is a good opportunity to try solving
the problem correctly.

if i add ActionOnPurge=None on all my pool, will it propagate to my
"waiting to be recycle" volumes or will i have to do something special ?

How should i do a test run with that without waiting for the next
recycling problem, which can occurs in a month or so ?

Below is my pool conf file:

Pool {
Name = AllIncrementals
Label Format = "Incr"
Cleaning Prefix = "CLN"
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Storage = gozer-sd_on_Batcave
Volume Retention = 1 months
}

Pool {
Name = AllDifferentials
Label Format = "Diff"
Cleaning Prefix = "CLN"
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Storage = gozer-sd_on_Batcave
Volume Retention = 1 months
}

Pool {
Name = AllFulls
Label Format = "Full"
Cleaning Prefix = "CLN"
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Storage = gozer-sd_on_Batcave
Volume Retention = 2 months
Maximum Volume Jobs = 2
}

Pool {
Name = CatalogFulls
Label Format = "Full"
Cleaning Prefix = "CLN"
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Storage = gozer-sd_on_Batcave
Volume Retention = 2 months
}

# Default pool definition
Pool {
Name = Default
Pool Type = Backup
Recycle = yes # Bacula can automatically
recycle Volumes
AutoPrune = yes # Prune expired volumes
Volume Retention = 365 days # one year
}

# Scratch pool definition
Pool {
Name = Scratch
Pool Type = Backup
}
