> > please reproduce it without heartbeat... "by hand" > Thanks. Lars, I actually experienced that fast then slow condition actually without heartbeat. (I was wondering what had been happening originally and was manually starting the drbd processes on each box). Anyways, after setting up NTP and resyncing the clocks (and a reboot), I was able to achieve pretty good throughput speeds. However, now I'm noticing I may have too much of a bottleneck between running a software RAID 1 on each box PLUS the drbd raid of those raid 1 volumes. I'm running some iozone tests first to see if I get noticeable improvements in performance. (Basically, I had apache logging via NFS to this pair of boxes, and the box ended up scaling out of control with load --- that is, the apache box went up to like a load of 20 whereas the nfs box went up to maybe a 2). Anyways, I was thinking to improve performance, it may make sense to switch the shared (drbd shared) drives to be based on a raid0 volume versus the raid 1. (I was also thinking it may be wiser to either pipe the apache logs to write to both spots, or simply do a regular rsync interval for the logs). Any thoughts on this? And, can anyone recommend an easy way to convert a raid 1 into a raid 0? doing partition management during install is easy with disk druid, but i'm lousy at disk management when it comes command line. Never had to deal with it that much. Thanks, Travis
