Re: [kde-linux] Kmail

We all learn now And I thank you - My experience with mirroring is I
admit to high end servers where you physically had to disengage the dud
drive...but thats a log time ago.

Thanks very much. I might configure my server as such when I upgrade to
new software soon.

Merry Christmas

Scott

Using RAID 1 is a good idea, however you need to be comfortable in

first HDD fails you will not have too much trouble utilising its mirror..
RAID 1 is easy to create, however in the event you need to use the
mirror partition solely comes the time for knowing exactly what to do.

No, Scott, that is not much of a problem. Even using software
raid, if one drive dies, the raid just fails the drive, and boots it out
and continues to run on the one remaining drive.

Its so smooth, you run the risk of missing the failure entirely.

When you add the new replacement drive, the raid just rebuilds
the array automatically.

I don't think any of the hardware raid controllers offer much
unless you are talking big enterprise level servers.
Software raid under linux is so reliable, and servers are
usually so un-loaded (cpu utilization hovering around 3%)
that the cost for the controller is better spent on ram.
