Hello, i'm testing DRDB 0.6.1-pre7, and i've some questions
first one, does anybody have update the run.sh script for benchmark ?
i've try to update it ... i think it's good ... but i've strange result
two nodes are exactly the same but i've very different result.

i've add -k options on the script (for all "net" command) because if i don't add it, the secondary node crash when the script unload the module and nodes are in SycingAll state (just at the end of the "Drbd connected (writing on node1)" part)
so i've no result for the node2 without -k option
but where it's really strange ... when i suppres "-k" options, node1 has about 5MB/sec for protocol A B and C instead of 2MB/sec.

here are reports for a test with "-k", and another without "-k"
i've also attached my modified run.sh

Thanks

Anthony Hinsinger
