Better than that, mirror the disk. Then when one drive fails Linux will automatically use the other disk. You can go one step more and define a third disk as a "hot spare" then after Linux detects the drive failure and switches to the surviving twin it will also bring up the hot spare and begin building a replacement for the dead twin. You can then swap out the dead drive with no need to power down the server and declare the new drive as the new "hot spare" I would mirror the read-only patition also It you truely want "5 nines" you have to set things up so that you can do normal maintanance (swapping out drives, power supplies and the like without powering down. > > It's probably possible to do it with another distro too but astlinux > is > already pretty much finished :) And the cost of 512 Mb or 1 GB ATA > flash > is not much more than a McDonalds meal anyways (1GB is about USD 100 > now) > > For voicemail I could also use a microdrive but I'm not sure what > will > happen if it breaks and * tries to read/write from it.
