 Posted: Sat Jun 28, 2008 4:16 pm Post subject: GFS on Gentoo |
 |
|
I want to have the same /home on several boxes and someone suggested I try GFS (Global File System). I looked up wikipedia page for it and its exactly what I was looking for, but I can't find any good guides for getting it to work in Gentoo.
I noticed a sys-fs/gfs in portage. That's what I need to install I'm guessing. But what do I need in terms of kernel options and how to use it once emerged?
Need n00b instructions 
Thx in advance. |

Sorry I can't provide you a direct howto, but since GFS is now on RedHat it might be a good starting point:
http://www.redhat.com/docs/manuals/csgfs/browse/rh-gfs-en/
Just to make sure, having the same /home on several boxes that comes from one server doesn't need GFS or some other cluster filesystem. If you just want to have one or more directories of one server exported to several clients, I suggest you stick with nfs. If you indeed have several servers and want to cluster their filesystems to one network storage, GFS might be the right choice. (I probably misunderstand "I want to have the same /home on several boxes ") |

lobstar,
Please explain exactly what you're trying to accomplish. Are you looking for similar functionality to DFS (in Windows)? |

PMFJI, but I think I have a similar wish, and perhaps this can clarify things, even in a negative fashion.
I'd like to keep /home coordinated/synchronized among several systems. Right now I've put /home on my nfs server, and mount it from my various desktops.
But what I'd really like is a tell-me-N-times filesystem. I'd like to have a copy of /home on each machine, and have writes from each machine routed to the others. That way it gives me local performance plus "network RAID-1" backup. I've looked a little at doing this, and one complexity is that my desktop machines aren't 24x7, so it can't be done simply. I'd be perfectly happy to have my server be a backup target, to cover that type of situation. But I see the need to dynamically attach/detach machines, and bring them up to date after boot as being one of the bigger problems. (Otherwise things like DRBD or RAID-1 over NBD ought to work.) Did I mention that I want writes to return immediately, rather than waiting for the networked write to complete? True local performance, etc.

GFS provides concurrent direct access to a single filesystem from multiple machines ... which means it is not what you want.
Look into AFS which provides a distributed, locally accessed filesystem ... |

I use AFS at work. It's a central-server filesystem, just like the NFS (V4) that I use at home. I was instead wishing for a truly distributed filesystem - the data all stays on client machines. There would likely have to be a server, but it would be a metadata server - telling which client contains the most up-to-date copy of each piece of data.
