[ovirt-users] two node replicated gluster
Hello List, i have a Two Node replicated Gluster. I am running about 15 vm on each host so that in case one node fails the other one can take over. My question is how the GlusterFS self-healing-daemon works. I disconnected the two nodes on purpose and reconnected them again. So that the self-heal-daemon jumps it. It looks like it would transfer all the file. Does the self-heal-deamon of glusterfs not just copy the missing increments? Thanks, Mario ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Does the self-heal-deamon of glusterfs not just copy the missing increments? self-heal daemon just syncs regions of files that need to be updated and the process of identification of regions to be updated involves comparison of a rolling checksum of various regions in the files. You can find more details about Gluster's replication and the self-healing algorithm in the Recovering from failures (Self-heal) section of this document [1]. -Vijay [1] https://github.com/gluster/glusterfs/blob/master/doc/features/afr-v1.md ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
