Gluster users - Dec 2009 - glusterfs-volgen in 3.0 broken?

Hi List,

somehow i fail to create volume files with glusterfs-volgen from the 3.0
release:

glusterfs-volgen --help
usage: glusterfs-volgen: -n <VOLUMENAME> -t <TRANSPORT> -p
<NUMBER> -a <AUTH> -r
<TYPE>

so i tried:

glusterfs-volgen -n test -t tcp -p 7777 -r 1 node01 node02

but only get

Error: no servers provided, please provide atleast one server

Does someone know why?

Also in the glusterfs-volgen from 2.0.8 there was a feature raid10 - this seems
missing - can i still use my old volume files from 2.0.8?

Somehow glusterfs-volgen from 3.0 does not work as expected - a manpage or more
verbosive usage-output would be nice!

Hi Wiessner,

You have to provide <server>:<exportpoint> with glusterfs-volgen as
of now.
So your command should look like:

glusterfs-volgen -n test -t tcp -p 7777 -r 1 node01:/export/mirror
node02:/export/mirror


Regards,
Amar

replicate should work fine, but it will be added in glusterfs-volgen only after
the team tests and certifies the configuration. Currently, only the configs
which are tested will be generated from glusterfs-volgen.

Confirmed - i tried replicate + stripe, stripe + replicate and replicate +
distribute and all works fine, though i found out that with 4 nodes the setup
like this performs best, giving me about 80mb/sek write, 100mb/sek read with
gbit connection:

volume mirror-0
    type cluster/replicate
    subvolumes node01 node02
end-volume

volume mirror-1
    type cluster/replicate
    subvolumes node03 node04
end-volume

volume stripe-0
    type cluster/stripe
    subvolumes mirror-0 mirror-1
end-volume
