    I am using two drives as mirrored drives (raid1) on two RH9 servers. On both
    servers, the raid setup has lost a device. I don't belive the drives are
    faulty, in fact I can boot with either and see data on the drives, however,
    it is older on one of them. I believe the drives have become out of sync doe
    to a crash at some stage.

    [root@loki root]# dmesg |grep raid
    raid1: md1, not all disks are operational -- trying to recover array
    raid1: raid set md1 active with 1 out of 2 mirrors

    [root@loki root]# cat /proc/mdstat
    Personalities : [raid1]
    read_ahead 1024 sectors
    md1 : active raid1 hda3[0]
          116093632 blocks [2/1] [U_]

    How do I resync them? There doesn't seem to be much literature out there on
    this that is current.

An experiment I want to run is to get a 4200 rpm SATA laptop drive and 10,000 RPM SATA Raptor of similar size and compare the responsiveness of the same install on the same hardware on different drives and then figure out what mountpoints should go on a CF card in a DMA capable IDE adapter to achieve similar speed, my hunch is I should put at least /var and /home on the harddrive and the rest on the CF card. ... RAID is not a substitute for backup anyway, it's meant to be a tool to increase availability by adding redundancy, in this case I could slap in a new drive, do a reinstall, rebuild my RAID1 array, and I'm back up without having to do all that tedious mucking about with DDS tapes but even if your data is hosed you can restore from backup and your fine. ...

The one think that RAID1 'was' in my mind always useful for was data protection so I'm thinking there must be a way whereby I can install all four drives so that only two are visible and the other two are a mirror image set so that at the end of the day, or maybe twice a day, some software would back up the main visible drives to the 'invisible' back-up drives. ...

No advantage in throughput, this is the simplest data redundancy configuration (one half of the mirror set can fail, the other set takes over as primary, replacement drives are automatically synchronised - which may hit performance). ...
