Hi, Attached is a patch for the users guide.
Also, I'm having an issue with sync performance. I have DRBD setup between two
hosts using SRP. Under optimal conditions I'm able to achieve a 500+ MB/s
write speed, but during the initial sync after the DRBD device is created the
sync proceeds at less than 100 MB/s. Below is the config file. Am I missing
anything needed to bump up the initial sync speed?
Also, all bytes on the drives on both side are zeros, so the limitation seems
to be in the crc32c processing.
Thanks,
Josh
