[clug] Effects of hacking on md

[Michael James]

We're having major grief on a server
 with md software raids rebuilding continuously.

I'm beginning to suspect attempts at hacking.

What would happen to a software mirror
 if somebody tried to bust out of a chroot jail
 by accessing the disks directly?
They'd dirty the mirror and trigger a rebuild
 wouldn't they?

And how does a mirror rebuild anyway?
I mean, I have 2 pieces of data, they're different.
Which is right?

It's all too much like a duck, only in this case,
 one of its legs are both a bit different.
