Chiron FS - A FUSE based replication filesystem

Quote:
Chiron FS is a FUSE based filesystem which implements replication at the FILESYSTEM LEVEL like RAID 1 does at the DEVICE LEVEL.
The replicated filesystems may be of any kind you want the only requisite is that you mount it.
No need for special configuration files, the setup is as simple as one mount command (or one line in fstab).


latest RC9 package download:
http://www.axxium.us/users.zenwalk.org/ ... 6-50.1.dep
http://www.axxium.us/users.zenwalk.org/ ... 6-50.1.md5
http://www.axxium.us/users.zenwalk.org/ ... 6-50.1.tgz
http://www.axxium.us/users.zenwalk.org/ ... s/ZENBUILD
http://www.axxium.us/users.zenwalk.org/ ... hironfs.sh
http://www.axxium.us/users.zenwalk.org/ ... /build.log


Please visit http://code.google.com/p/chironfs/ for more info


Testing Chiron FS:


After install,

Step 1: Create 3 directories, one for the virtual filesystem and two for the replicas

        mkdir /virtual /real1 /real2

and do the mount with the commands;

        chironfs /real1=/real2 /virtual

Step 2: Confirm they are correctly mounted with the command:

        df

You should see a line like this:

        /real1=/real2  138456396 130613500    809640 100% /virtual

Step 3:Try to create/modify/delete some files in /virtual and check for the reflections in /real1 and /real2.

At this point you may be convinced that you have everything you need to start replicating your files. So umount it with the command:

        fusermount -u /virtual

;)

well, I package this because I probably need it for ZUT, but for general purposes, maybe you can get some ideas from the official website:

http://www.furquim.org/chironfs/about.html

Basically, it groups any two (or more) folders and make them functions like RAID1. Which means:

1. Real time backup
2. Auto fail-over if data on one folder is missing
3. The folders can actually come from NFS, sshfs ... etc. So real-time file redundancy across several machines is made possible ;)
4. It's perfect for clustering or web hosting ... or for anyone that wants a lazy backup solution.

I think it's very useful in many cases, for ZUT it means I can merge several local repo into one. ;)

:o

I suddenly noticed that this software only releases under GPLv3 !

Can I still package it into extra repo?

::)

:D ok! Thanks! I was just worrying about the license issues ...

Does anyone like to try it and report test results please?

:)

Hello

I am the author of the software and I am very happy to hear that it is being useful for
you \!D/ . If you have any questions/suggestions/reports etc, feel free to contact me.

I will be publishing the 1.0-RC9 in the next days. It will fix the security bug reported at
http://code.google.com/p/chironfs/issues/detail?id=8 . I delayed that publishing because
I am writing a test software to automate the test of the security by performing a set of
operations both in a Chiron FS subtree and in a real filesystem (non ChironFS) subtree
and checking if the results are different.

Thank you for your attention

Hi luisfurquim:

First of all, I'd like to thank you for the great idea and the effort of coding devoted to this project. I found it when I was searching solutions of file system fail-over for the two clusters in the place I work. although eventually we didn't deploy it because some other guy had wrote an cron-backup script to copy everything in real-time (... Yeah, I know ... That is ...) but I really like the concept and the simplicity of the project.

IMO, Zenwalk Linux also focuses on simplicity and provides an OS with unique design and taste. That's a big reason I built the package. For my personal purposes, I'm planing to use it on a little script I wrote for Zenwalk.

Thank you again for dropping by. I am looking forward to the RC9 release. 

Oh and, just wondering, any chances that you can become a Zenwalk user as well?  ;D

Best regards,

infwonder

Hello infwonder:

Glad to hear it! I just downloaded the Zenwalk Standard. I will try it this night  X!! . Three things I notice that
are of great interest for me: It runs light on old machines, it has multimedia support and development
support out of the box  ;) !

Best Regards

Luis Otavio Furquim

I got an email from the developer (luisfurquim) said he had the latest RC9 released which fix some security issues. This version has been out for a week or so and so far no bug report at all! He think this should be a rather stable release but still want it to be widely tested before removing the "RC" tag.

Let's help him!


Testing Chiron FS:


After install,

Step 1: Create 3 directories, one for the virtual filesystem and two for the replicas

        mkdir /virtual /real1 /real2

and do the mount with the commands;

        chironfs /real1=/real2 /virtual

Step 2: Confirm they are correctly mounted with the command:

        df

You should see a line like this:

        /real1=/real2  138456396 130613500    809640 100% /virtual

Step 3:Try to create/modify/delete some files in /virtual and check for the reflections in /real1 and /real2.

At this point you may be convinced that you have everything you need to start replicating your files. So umount it with the command:

        fusermount -u /virtual

latest RC9 package download:

Hello

First of all, I would like to thank you for the attention with
ChironFS!  ;D

As I told to Infwonder, this version is a strong candidate to
be the stable version. But to be sure that it really is,
feedbacks are essential!

So I would appreciate any help you could provide: tests,
suggestions, etc.  H!!!

Again, thank you!

Best Regards

Luis Otavio Furquim
