Hi together. Every now and then "bad" or "unusual" configuration is blamed for - slower than expected sync speed - frequent disconnects/reconnects - triggering bugs like the sendmsg() problem unusually often I'm talking DRBD 8 here btw. Is there a set of recommended configurations for typical situations, as in "best practice guideline"? I assume that our usage pattern is very common for DRBD8: - dedicated GBit connection between 2 nodes - "TCP Offload Engine" of network card not trusted - 1 heavy-load drbd resource mirrored - discs backed by RAID ctrl. with lots of cache, and batteries Any links or suggestions? If someone is willing to take a recommendation flowchart (or assistant) a step further, here are ideas for variables: - "TCP Offload Engine" of network card trusted or not - discs battery-backed or not - n drbd resources mirrored (n = say 1, 10, 100). - connection speed (100 MBit, GBit) - connection distance & realiability (as in local vs. near vs. far away) TIA, regards, Christoph
