Re: [Bacula-users] New tape drive
Hello,My experience is that the larger the block size one uses the more prone the drive is to errors especially when the drive is dirty. A number of years ago I had the chance to speak to a Quantum tape expert and he recommended a max of 500K -- at that time we were talking about an LTO-5. Since then tape technology has improved significantly, but just the same at some point when increasing the block size more errors will occur. I recommend testing various block sizes to see what the performance gains really are as I suspect from my own testing that performance increases quickly become minimal. Unless there are some spectacular performance increases, I would not recommend block sizes of more than 1-2 megabytes on LTO-6 and above and 1 megabyte max for LTO-5.Best regards,KernSent from my Samsung Galaxy smartphone.

Re: [Bacula-users] Tape issue: less size than before for LTO-4 tapes
Hello,From the error message printed by Bacula (in German) I would strongly suspect that something caused a reset on the drive or the auto changer. This can happen if two processes are using the changer at the same time and someone is issuing a smartctl or another such program.I would recommend that you enable Bacula's TapeAlert code, which is not on by default. It will keep a record of any tape alerts, which could help you track down the problem.I would also recommend that you do two cleanings of each drive. One cleaning is not always sufficient (or more correctly said, one cleaning did not resolve a tape proble I had on an LTO-4 drve).Best regards,KernSent from my Samsung Galaxy smartphone.
