Hi David and Joaquin, Actually, the config is this (my previous description may be a little confusing): ---------------- Computer OS Disk (failed) AMCC 9650SE-2LP Raid Controller (SATA II, PCI-e) 3Ware - 2 Disks mirrored (OK) ]______|-- Linux striped the 2 mirrors AMCC 9650SE-2LP Raid Controller (SATA II, PCI-e) 3Ware - 2 Disks mirrored (OK) ]______| (mounted as /home/Data) ---------------- Naturally, the controllers can only do Raid 1 or 0. I mirror 2 HD's on each controller. If one disk in the 2 mirrors fail, I can rebuild it with the HW raid controller. If 2 on the same controller mirror fail, I have a problem. The chance of this double failure on the same controller is slight. I have not yet in the last 6-7 years have a 3Ware controller failing. Not sure what will happen when one controller fails. I assume I can just replace the controller and it will pick up the config from the disks. Anyone know if a controller replacement will pick up the mirror? The 4 port 3Ware controllers (9650SE-4LPMLRaid Controller) do work if replaced, because the raid config is also on the disks, as far as I can hopefully recall correctly. I have not had a 3Ware fail yet, thus I lack the experience. I am considering replacing the 2x2 Ports with a 1x4 Port to have a HW-raid 10 without needing a Linux soft raid, for more safety; I just have to scratch the money together first. I will try with the openSUSE Live CD as Joaquin suggests, to make another backup of the raid (to be sure), and do a new install of the OS as David suggests. Thanks for the tips. :-) Al -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
