Btw.: i've seen in the munin stats that the disk utilization for bricksdd1 on the healthy gluster servers is between 70% (night) and almost 99% (daytime). So it looks like that the basic problem is the disk which seems not to be able to work faster? If so (heal) performance won't improve with this setup, i assume. Maybe switching to RAID10 (conventional hard disks), SSDs or even add 3 additional gluster servers (distributed replicated) could help? _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx https://lists.gluster.org/mailman/listinfo/gluster-users
