Re: [OSR-users] rpms for ocfs2+rhel5

(sorry, I accidentally posted this to -devel the first time)

Hello --

I am a Xen developer and I would like to experiment with
open-sharedroot on rhel5+ocfs2 on Xen but I am having some
network problems and have not been able to download the
3.6G DVD iso.  Is there any way I can download just the
necessary .rpm files? (i386 only is OK for now)

Also, I have ocfs2 v1.4.1-1, not 1.3.9-0.1.  Will the
specific versions of the rpms listed in the how-to
work also with ocfs2 1.4.1 or will I need newer versions
of the coomonics rpms?

And is the rpm listed in the document (and below)
as "el6" a typo?

Thanks,
Dan

List of rpms from the how-to:
# comoonics-pythonosfix-py-0.1-1
# comoonics-bootimage-listfiles-1.3-6.el5
# SysVinit-comoonics-2.86-14.atix.1
# comoonics-cluster-py-0.1-12
# comoonics-cdsl-py-0.2-11
# comoonics-bootimage-1.3-32
# comoonics-release-0.1-1
# comoonics-cs-py-0.1-54
# comoonics-bootimage-initscripts-1.3-5.el6
# comoonics-bootimage-extras-ocfs2-0.1-1
# comoonics-bootimage-extras-xen-0.1-3 (Only needed for xen Guest)

Normally it should work. I didn't test it with these versions. On thing that 
comes into my mind is if you are using ocfs2 via openais (this will not work 
out of the box) or via the oracle cluster stack (that is supposed to be 
working).

I hopefully will release in the next days a new version of the comoonics rpms 
that are also validated against RHEL5 with ocfs.

Re: [OSR-users] rpms for ocfs2+rhel5

[Dan M. <dan...@or...>]

Finally got the rpms and installed.  One other typo on
the rhel5/ocfs2 webpage:

comoonics-bootimage-1.3-33 (not -32)

as comoonics-bootimage-extras-ocfs2-0.1-1 depends
on -33.

On to the next step! :-)

Do I need a redhat cluster.conf file other than to
have the ocfs2 cluster.conf file created from it?
In other words, can I just start with my own
/etc/ocfs2/cluster.conf file?  Or will the other
installation steps require /etc/cluster/cluster.conf?

Thanks,
Dan

Thanks. I fixed both typos. You might want to check if those are ok now.

Yes, this is something I don't like either but as I had no customer willing to 
pay for it I took the simplest way ;-).

That means up to now you need a /etc/cluster/cluster.conf based on redhat 
cluster. And on the other side it wasn't possible to extend the ocfs 
cluster.conf with attributes.

So in the current state you will have to create a cluster.conf. This will be 
the base for the /etc/ocfs2/cluster.conf which will be automatically 
generated by com-queryclusterconf convert ocfs2. To validate the output you 
can use the command. It should return something like below:

[root@generix3 ~]# com-queryclusterconf convert ocfs2

node:
        ip_port = 7777
        ip_address = 10.10.10.83
        number = 3
        name = generix3.local
        cluster = clu_generix

node:
        ip_port = 7777
        ip_address = 10.10.10.82
        number = 2
        name = generix2.local
        cluster = clu_generix

node:
        ip_port = 7777
        ip_address = 10.10.10.84
        number = 4
        name = generix4.local
        cluster = clu_generix

cluster:
        node_count = 3
        name = clu_generix

Does that help and make sense?

Marc.

Thanks, yes.  But I would like to test the process by
creating and booting a one-node (or at most two-node)
cluster and then "grow" it later to a larger cluster.
Is this possible?  If so, what parts/scripts of the
howto will I have to re-do when I am ready to grow
it from one-node (or two-nodes) to many?

Thanks,
Dan

Re: [OSR-users] rpms for ocfs2+rhel5

[Dan M. <dan...@or...>]

OK, I've finished the howto, trying to reasonably substitute
where necessary for the fact that I am going to boot the
osr as a xen guest (running 2.6.28 as the guest kernel).

Note that I am running the howto in a Xen EL5 guest booted
with 2.6.28 and with an ocfs2 filesystem mounted in the
guest as a second disk "/extra"... so wherever I see
/mnt/newroot, I am substituting /extra.

All seems to go smoothly until I get to the last step...
the mkinitrd complains loudly and lengthy.  It can't find
a list of rpms and skips:
- comoonics-cs-xml
- kmod-gfs
- gfs-utils
- cman
- openais
- lvm2-cluster
- OpenIPMI-tools
- xen
- xen-libs
- libvirt

Then the /boot disk fills and I get cpio errors.  It appears
that an intird...img.tmp file is created that is 78MB in size.

Oh dear... it also looks like the grub part of the howto has
changed /boot/grub on my running system, not on the /extra
disk?!  And now I can't boot that guest anymore at all!

When I have a chance, I will restart with a fresh EL5u2
guest and document every step from the beginning, but
if you see any obvious solutions, please let me know.

Thanks,
Dan

That should not be a problem. BTW. I also made the howto for nodes running in 
XEN with EL5. So that should fit.

You can ignore those. These are only warnings (I don't like them either and 
they will go away in the future) for rpms not to be found. Most are related 
to GFS and RedHat Cluster or xen Dom0. You can siltently ignore then.

Yes. It might be that the boot disk is too small. A workaround would be to 
first create the initrd in /tmp. I.e mkinitrd /tmp/initrd_sr... and then 
copy/move it to boot. I've done this whenever the bootdisk was too small.

Yes, the bootdisk normally resides on a special disk and therefore must be 
handled specially. See above for a workaround.

If possible let the /boot be 1G.

If ocfs2 does support it we do as well. I think you just need to add a node to 
the /etc/cluster/cluster.conf build a new initrd and then boot the new node.
Additionally you need to have the hostdependent files ready for that node as 
well. Those will be found at /cluster/cdsl/<nodeid>. Best if this directory 
is not there it to either copy /cluster/cdsl/default 
to /cluster/cdsl/<nodeid> and then adapt the hostdep. files.

Hope that helps
