Re: [MooseFS-Users] Lots of missing file in single server fault

[Piotr R. K. <pio...@mo...>]

Hi,

> By the way, in theory the chunks of a file whose goal is set to 2 are stored in different server or just different disk?

They are stored on different chunkservers. It is one of principals of MooseFS.
So e.g. if you want to store files in goal 4, you have to have minimum 4 different chunkservers.

Best regards,

But I discovered that though I set goal to 2 for every file, there still have some missing file when one server is down. So now I want to keep access to every file in single server fault, what should I config?
