It sounds like your tape drive.  One of the tape heads is clogged.  There are 4 
tape heads, when one gets clogged, it writes using 3 tracks, instead of 4.  If 
your capacity is 200g, then with 3 heads it is 150g + compression.

So your tapes are full at that time.  Look up lt04 tape head clog.  I know I 
saw an article with that search before.

When it happened to me, I could not unclog the heads and needed a new drive  :(

Subject: [bareos-users] Tapes marked as full but they're not

I have a recurrent problem when running copy jobs to my LTO2 tape device.

At work I have a "WeeklyPool" on disk which is used to make full backups every 
Saturday.
The copy job copies then the last uncopied jobs to a "WeeklyCopyPool" on tape 
so I can take it off-site.
Currently a full backup takes ~180GB and our LTO2 tapes have a 200GB capacity.

When running the copy job, at some point Bareos marks the tape as Full and 
waits for another tape but the tape is not full.

This problem happened from time to time in the past. Purging the tape or using 
a different one and running the copy job again worked, but in the last weeks it 
has become worse and I can't complete any copy job without having the tape 
marked as Full.

I've already tried running the copy job on different tapes and cleaning the 
tape drive with the cleaning tape, but it didn't help.

Here the message I get when the tape is marked as full:

Is it a bug in bareos or a problem with my tapes/tape drive?
