Hey, good news! I got my speed back! :) When I moved Bacula onto the new server-box I changed the cable as well, cause the new server was a bit far away from the tapelibrary. Cable length was ~2m. Should be ok, though.
Now I plugged back the old cable and .... tadada .... Wrote blk_block=5000, dev_blk_num=4999 VolBytes=322,495,472 rate=14658.9 KB/s Back in business, phew. I did check a few more things that changed during the last two days: - kernel module: aic7xxx vs. aic7xxx_old -- both running at full speed now - block size : 0 or 1024 or ... -- full speed now - stoptions : -- just made it worse when not all set Oh and I changed from 1.38.2 to 1.38.3. Have a nice day, me off for a beer. ;) Michael On Tue, 10 Jan 2006 - 12:31pm, Michael 'buk' Scherer wrote: >Hey. > >Quick test with 1.38.3 still shows: >Begin writing Bacula records to tape ... >Wrote blk_block=5000, dev_blk_num=4999 VolBytes=322,495,472 rate=3193.0 KB/s >Wrote blk_block=10000, dev_blk_num=9999 VolBytes=645,055,424 rate=3193.3 KB/s > >So not much improvement on my side. :o\ > >Any other ideas? > >Greetings, > > Michael > >On Tue, 10 Jan 2006 - 11:20am, Arno Lehmann wrote: > >> Hello, >> >> On 1/10/2006 10:58 AM, Michael 'buk' Scherer wrote: >>> Good morning. >>> >>> Just to let you know: >>> I ran into the exact same problems as Chris after upgrading to 1.38.2 and my >>> yearly backup runs for 2 days now at ~3MB/s. >>> Before that I had rates around ~12-14MB/s which was what I would expect. >>> >>> I did the bfill tests before as well and got rates around 3MB/s as well. >>> The box has nothing to do except for the Bacula stuff, no other load. >>> >>> I _THINK_ it occured after I did the defblksize thingy but couldnt verify it >>> yet, because I need my backups to finish before. *sigh* >>> I also executed the other option command which I didnt do before, on the old >>> box. >>> >>> I'll keep you informed. >> >> Oh shit. >> >> It took me a while to notice a little part of the above text... something >> Chris >> mentioned earlier, IIRC, too. >> >> My advice: upgrade to 1.38.3 >> >> I had the same throughput problem with 1.38.2, but it went away once I >> started >> using 1.38.3. >> >> I feel really stupid that I didn't think about that earlier... after all, I >> spent quite some time because of this problem. >> >> Arno >> >> > > > -- I love deadlines, especially the sound they make as they go whooshing by. ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
