[Linux-cluster] Performance of ES3+GFS6.0+GNBD+LOCK_GULM

[Hong Zheng]

Today, I tried the configuration with lock_nolock. I configured one GFS
node with lock_nolock and the performance acts as a local drive. But
here is the question, I still want to make it as a cluster at least a
active-passive cluster. Since for active-passive cluster every time
there is only one active node, I assume the data will be consistent when
the backup node takes over. I'm not sure if this is a compromise way to
keep the better performance and data consistence.

Thanks, Kevin.

 

Actually I did try the way you recommend. I configured one GFS
application node with software iscsi initiator and two lock_gulm
servers, the data transfer speed just improved a little bit, but for our
application the performance is about the same. Do you know if there is a
way to tune GFS performance?
