Gluster users - Sep 2010 - [3.1 Beta]: raid 1 volume with gluster command and some other questions

Hi,

I am new to the list, because i am currently trying out the new 3.1  
beta glusterfs and cannot find informations on the web how i can  
create a volume with the new gluster command which is also replicated.

The second thing i don't know is how i can activate translators and  
authentication with the new gluster command.

Is there some "hidden" documentation somewhere?

Thank you for your help.

Regards,
Christian

You need to have 'glusterd' started before running any of the gluster
commands.
Sequence of commands looks like below:


bash#  glusterd  #<if its not a RPM install, add this command in rc
scripts>
bash#  gluster peer probe <Other Server IP>   # Do this for every storage
server
bash#  gluster volume create test-mirror replica 2 <brick1> <brick2>
...
<brickN>

Where, 'test-mirror' is volume name, (and it can be anything string)..
and
brick1 -> brickN are in the format, <server>:<export-dir> format,
and N
should be multiple of 2 (as we gave 'replica 2')

Then, you can start export processes using,

bash# gluster volume start test-mirror

You are ready to go... On any client machine (where there is FUSE) you can
do..

bash# mount -t glusterfs server:test-mirror /mnt/glusterfs

If one doesn't have fuse, and want to have NFS clients, do

bash# mount -t nfs server:/test-mirror /mnt/nfs

 I didn't understand the question clearly.. can you re-phrase it? What do
you mean by 'activating translator' and what is 'authenticating with
new
gluster command'?

Documentation is in progress and we intent to get everything upto the mark
soon. You can find 3.1 related docs here :

http://www.gluster.com/community/documentation/index.php/Gluster_3.1_Release_Notes:_Introduction

http://www.gluster.com/community/documentation/index.php/GlusterFS_3.1beta


And there is nothing 'hidden' if it gets written. The problem is
whatever is
in code/working is not yet penned down..

This should be actually the line I haven't found documented. But  
probably i just didn't search for it hard enough.
Is the argument "replica 2" already documented somewhere os should i  
browse the code in the meantime for all the possible arguments to  
gluster command?

Ok, i try it again. There therea are translators available in  
glusterfs (see [1]). How do i set the translaters in 3.1. E.g. the  
quota translater, how/where do i config it. I thought it should be  
possible to do this with the gluster command otherwise i have to  
manually configure glusterfsd.vol files on all nodes. How do you  
achieve translator configuration in Version 3.1? Or better: What is  
the best/recommended way in 3.1 to achieve this?

The second part of the question is about the authentication mechanism  
in glusterfs. IP based and user/password based. What's the best way to  
configure this feature in 3.1? In the previous version you had to  
manually change the glusterfsd.vol files.

Sorry for the missunderstanding, I meant 'hidden to me' in the sense I  
wasn't able to find documentation regarding my questions for 3.1
