[Pacemaker] [PATCH] pingd: set ICMP6 filter
Hi all,
I'm posting patch for pignd in Pacemaker 1.0 (changeset:6cf252e61e25).
This patch sets the filter of ICMP6 and fixed some bugs.
I hope they are helpful to you.
Regards,
Kazunori INOUE

[Pacemaker] fedora11: openais fails to start
Hi, I wanted to try pacemaker/openais on a fedora11. Packages from OSBS: # rpm -qa | grep ais\|pace pacemaker-1.0.5-4.1.i386 libopenais2-0.80.5-15.1.i386 pacemaker-libs-1.0.5-4.1.i386 openais-0.80.5-15.1.i386 pacemaker-mgmt-1.99.2-6.1.i386 When I start /etc/init.d/openais start - There are some entries in the log. Nothing what I could identify as an error. See: http://www.pastebin.org/41120 - openais-cfgtool -s stops at Printing ring status. Need to CTRL-C to stop. - No pacemaker process are really started: ps uax | grep crm is empty. Any ideas? Using corosync-1.0.0 from fedora11 is no option.

[Pacemaker] Access CIB/CRM via IPC/Library?
Hi All, after having understood the concepts (if not all details) of configuring Pacemaker (Configuration Explained does a good job) I started checking out how to actually create/activate a configuration. Seems that there's some GUI (wherever it is, it's not included in my packages, but we don't need it anyhow) and the command-line utilities crm and cibadmin. However what we really need is a more direct access in order to programmatically change the cluster configuration [without calling out to the command-line utilities from Python or C]. It also seems that crm and cibadmin use libcrmcommon to communicate via the Unix sockets in /var/run/crm. Is this library documented anywhere? Are there Python-bindings? Is there any other officially supported API? Thanks, Colin ___ Pacemaker mailing list Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker
Re: [Pacemaker] fedora11: openais fails to start
You could try the f12 rpms - we have tested these. We are in the process of making these available in f11/f10, but there is a bit of a lag because of fedora process. The f12 rpms are at koji.fedoraproject.org. From looking at your logs, it appears iptables is enabled and not configured properly. try service iptables stop.

Re: [Pacemaker] crm command syntax for defining multiple instance_attributes
Hi Andrew, According to the Pacemaker Configuration Explained, the meta attribute and instance attribute object can have rule inside of it. But cibadmin command does not accept it. Is it a documentation error or bug in software?

[Pacemaker] Recommended versions for the cluster stack?
Hello: I'm trying to set up a pacemaker/openais cluster on Gentoo, which requires building the entire stack from source. I have everything running, but the stack has some strange stability issues, (in particular during a reboot), that I'm sure are due to some version incompatibilities. What software versions comprise the recommended stack for Pacemaker? (I.E. what versions are currently tested and/or in production?) In particular, I am interested in the version numbers of: pacemaker openais libdlm drbd and ocfs2 If my software versions aren't too far off, I'll post my logs after the weekend. It's been a frustrating afternoon trying to get my cluster back up. Thanks! Jonathan -- J. deBoer Computer Consulting. 42 Birchmont Dr. Leduc, AB.

Re: [Pacemaker] Recommended versions for the cluster stack?
I do not know what the recommended versions are, but I wrote ebuilds for the pacemaker/corosync cluster stack with the latest versions that were available at the time. They are located here http://code.tjhsst.edu/vm-overlay/vm-overlay. I believe there might be a small bug in the permissions in the pacemaker ebuild, but I do not remember if I fixed it. We are currently using the ebuilds in a testing environment running semi-production services (secondary mailserver, nameserver). However, we do not have need of dlm, drbd, or ocfs2 yet. If you do use ebuilds, please respond with what you used, or if you modify mine, how you modified them. Thomas Georgiou P.S. Now I see you already have things installed. Did you install them by hand, or through ebuilds?
