All of my servers are hardware RAID-6 with 8x300GB SAS 15K (some servers with 600GB) A rebuild of a single disk in a 6x600GB SAS RAID-6 takes exactly 22 hours. This with 15K SAS disks. Now try with 2TB (more than twice the size) SATA 7200 (less than half speed) _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-users
