Hello.

That's my first cluster setup! Let me describe what i did!

1- Installed Fedora 4 on 3 partitions:

/dev/hda2 - > /boot 150mb
/dev/hda3 - > / 16.000mb
/dev/hda5 - > LVM 10.000mb

2- Runned some commands after a search on the web. Seems i created a
group called group1!.

>pvcreate /dev/hda5
>vgcreate group1 /dev/hda5
>lvcreate -L1G -nmy_logical_volume group1
>vgchange -a y group1

Now, if i am right, i have to create the filesystem on this group, but
all the commands now go wrong. Tried mkfs_gfs ..., mount -t gfs,... but
everything goes wrong.
Found on the net too, references about a file
"/etc/cluster/cluster.conf" but this file does not exists on fedora.
Even the directory /etc/cluster.

What's up next? What do i have to do?

Thanks.

It would have really really helped if you had posted the exact
error messages, even if they don't tell you much they would have
told us lots about the problem.

Random guess, you don't have the needed support for GFS in your
kernel and need to install ~gfs-kernel package or however it's
called.

Ok. Thanks for your reply.

Fedora 4 as i read on the web has complete support for gfs. I know too
that it has a tool called lock_dlm that does the locking stuff.

I didn't posted the messages cause i didn't know if i am on the right
way...lol...

So i have now to create the file system and the tool for that is
gfs_mkfs?

Let me describe some tries:

>gfs_mkfs -p lock_dlm -t myclust -j 8 /dev/group1/my_logical_group
locktable error: missing colon in the locktable

>mount -t gfs /dev/group1/my_logical_group /mnt
GFS: not a GFS filesystem
mount: wrong fs type, bad option, bad superblock on
/dev/group1/my_logical_volume

That doesn't appear to be the proper syntax, see 'man gfs_mkfs'
"EXAMPLE".

[..]

BTW
If you are replying from google groups do not use its default way
which does not quote the text you are replying to. This makes it
harder for people not using google groups to help you while at
the same time annoying regulars on a daily basis. IIRC there
is an option to show text and then you can use the reply button
at the bottom. Please use that, thx.

Ok. I tried now the example and got success! Here goes the command:

>gfs_mkfs -t mycluster:mygfs -p lock_dlm -j 1 dev/group1/my_logical_volume

Device: /dev/group1/my_logical_volume
Blocksize: 4096
Filesystem Size: 229332
Journals: 1
Resource Groups: 8
Locking Protocol: lock_dlm
Lock Table: mycluster:mygfs

Syncing....
All Done

Now, let me ask:
Why the filesystem size is not 10.000mb as the partition was?
What is this journals? How many of then i have to use?
Resource Groups is the max number of computers i can have in a
group?

After the success command, i tried to mount and then got error.
Please, look:

>mount /dev/group1/my_logical_group /mnt -t gfs

GFS: Trying to join cluster "lock_dlm", "mycluster:mygfs"
lock_dlm: cannot get cman reference -107
lock_dlm: init_cluster error -107
GFS: can't mount proto = lock_dlm, table = mycluster:mygfs, hostdata =
mount: Transport endpoint is not connected

Now let me answer, try the docu first:

http://www.redhat.com/docs/manuals/csgfs/

"Red Hat GFS 6.1 Administrator's Guide" should answer your
question and hopefully enable you to get things working.

Good luck

BTW
Doesn't seemed to have worked with quoting, but thy for trying
anyway.
