I am working on a server. The server is normally in a remote location, not outside accessible by network, and there is no easy method to do backups on it. It is running Fedora 14 It has 2 hard drives at present, and there are 5 partitions on each. From this we have 3 RAID1 md devices. These are for /boot, /data and / I wish to add a 3rd disk, for enhancing the safety of the data. There is no space to add a 4th disk. Things I thought of doing include: Add 3rd disk to make a 3 disk RAID1 Make a RAID10, missing one disk. Which do you think is the better means to enhance data safety / chances of surviving a hardware problem? One of the above, or an other configuration? And, assuming I want to preserve the existing data, what is the best way to do this? -- Cheers, Maurice Hilarius eMail: /mhilarius@gmail.com/
