Hello, I have started building my first cluster with 3 nodes using CentOS 5.4. Two nodes have disk mirrored using DRBD, and third node is accessing it using GNBD. We're still not in production, but I wanted to test backup procedures. All web files will be copied to the remote server using rsync. There are about 3 milion files, mostly small. Rsync is very slow in creating file list, little faster than 100files/s. I have added: <dlm plock_ownership="1" plock_rate_limit="0"/> <gfs_controld plock_rate_limit="0"/> to cluster.conf. Also tried to manually add options to gfs_controld in cman init script. Nothing made rsync faster :( Is there any other tuning I can use to make GFS2 faster in this scenario? Does anyone use rsync in similar scenario, and how fast is file list created? I assume it has something to do with locking, but I couldn't find suitable settings, except plock_ownership and plock_rate_limit, which have already been included in cluster configuration file.
