    I have a Linux dedicated server with 1and1. The secondary drive on their RAID1 went bad, and they replaced with a new one. They've sent me the instruction (http://faq.1and1.com/dedicated_servers/root_server/linux_recovery/10.html), but the values don't match with what I have, and I don't wanna do anything I'm not so sure about, as it could wipe my good drive.

    1and1 hasn't been very helpful, so I'm turning to you experts for help. Please tell me what I should do.

    Here's the info:

    Excuse me, but can someone tell me how this question relates to the Plesk?

    I'm sorry, my host service runs on Plesk 11.0.9 Update #32, CentOS 6.3. I think I might've figured it out though, so please remove this thread.

    Sorry for the fiasco.

    Maybe we could have a Non-Plesk-specific section in the forum for generic technical questions, hints and tips? I know there are other forums for such things, but I suppose it might be useful to have one here too.

    Such issues are rare, and I think that we can solve them within the current structure of the forum.
