Hi all, For the second time this year I have experienced backups failing due to tapes filling up:
06-Feb 22:16 bacula_sd JobId 42315: Writing spooled data to Volume. Despooling 5,368,719,418 bytes ... 06-Feb 22:17 bacula_sd JobId 42315: End of Volume "LTO-W20141230A" at 1417:11071 on device "Quantum LTO-4 HH" (/dev/nst0). Write of 64512 bytes got -1. 06-Feb 22:17 bacula_sd JobId 42315: Re-read of last block succeeded. 06-Feb 22:17 bacula_sd JobId 42315: End of medium on Volume "LTO-W20141230A" Bytes=1,391,739,503,616 Blocks=21,573,342 at 06-Feb-2018 22:17. 24-Jul 22:20 bacula_sd JobId 44771: Writing spooled data to Volume.

What I'm puzzled with is the exact moment a tape fills up. LTO-4 cartridges are supposed to offer 1.6TB capacity but report as full much earlier (at 1.39 and 1.20 TB respectively). Is the capacity dynamic, i.e. decreases with the number of writes as tapes age and wear down? It could make sense as the tape from February was put in service in 2014 and the one from July in 2011. Can somebody explain it? Is it possible to anticipate when a tape is going to fill up? Is it time for me to retire and replace the oldest tapes?
