I can't seem to get Maximum block size = 1024K to work, I can't label the tapes either with btape or bconsole;When I revert it to 512K, the labeling works as expected, maybe the drive isn't capable of managing 1M block sizes? Whilst being in the btape CLI, I was running test and when Max block size is set to 512K I get the following; Doing Bacula scan of blocks: 1 block of 524224 bytes in file 1 End of File mark. 2 blocks of 524224 bytes in file 2 End of File mark. 3 blocks of 524224 bytes in file 3 End of File mark. 1 block of 524224 bytes in file 4 End of File mark. Total files=4, blocks=7, bytes = 3,669,568 End scanning the tape. We should be in file 4. I am at file 4. This is correct! The above Bacula scan should have output identical to what follows. Please double check it ... === Sample correct output === 1 block of 64448 bytes in file 1 End of File mark. 2 blocks of 64448 bytes in file 2 End of File mark. 3 blocks of 64448 bytes in file 3 End of File mark. 1 block of 64448 bytes in file 4 End of File mark. Total files=4, blocks=7, bytes = 451,136 === End sample correct output === If the above scan output is not identical to the sample output, you MUST correct the problem or Bacula will not be able to write multiple Jobs to the tape. When I removed the Max Block size property the sample and scan output are identical, should I be worried?
Hi Gilles, If the tape drive does not accept 1024K block size stay with 512K. The btape test looks all good to me. If you demand a block size of 512K the output cannot be identical to a sample 64K block size, right? The important parts are blocks per file, file count / EOF marks. HTH, Udo
