Hi everyone, I'm having some problemas with LTO-2 (200/400GB) tapes. The least I expect is that this tapes can record the 200GB off uncompressed data. I need to create monthly tapes that uses approximately 180GB but I'm not able to create this tape because they acuse they are full. With GZIP compression enable in bacula, the tape stop recording at 120GB. Without GZIP compression, they go to 160~170GB and request another tape. Other tapes that were working well on daily backups started going to the same way. I can't figure it out what is going on. I use this tow commands below before labeling a tape:
mt -f /dev/st0 rewind mt -f /dev/st0 weof I tried using "mt -f /dev/st0 erase" to, but I get the same problem. I saw some people talking about enabling tape compression with "mt -f /dev/st0 compression" or "mt -f /dev/st0 defcompression 1" but this commands didn't work with me. I also tried to use btape do rewind the tape. No success too. Here is my Storage Daemon configuration: Storage { Name = dataprom-sd Address = 192.168.1.27 SDPort = 9103 Password = "password" Device = HP_LTO-2 Media Type = LTO-2 Autochanger = no } Here is the error I got when the tape was marked as full: 31-Mai 19:27 dataprom-sd JobId 21030: Fim do Volume "Mensal09" em 147:6546 no dispositivo "HP_LTO-2" (/dev/st0).

Why the tape was marked full before getting to its capacity limit? Is there another way to format these LTO-2 tapes? Thanks for your help!
