Roberto, what would the advantage(s) be with your setup, ie one RAID1 array for everything but /boot compared to what I had done, ie three RAID1 arrays for /boot/efi RAID1, /boot RAID1 and one LVM-RAID1 for / and /home? As a naive user it would seem to me that the setup I did would be more resilient if a disk fails, or? _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
