[opensuse-ha] Samba AD domain + CTDB
by steve 08 Jul '14

08 Jul '14

13.1 nodes with drbd and ocfs2 from the ha-factory repo. Hi First time here so please be gentle. Aim: add second failover file server for our AD domain. First time here so please be gentle. We have drbd and ocfs2 up on 2 nodes. We want to add ctbd on top of that for failover. The documentation: https://ctdb.samba.org/samba.html makes no mention of AD. In particular, how to join the cluster to the domain. 1. What next? Do we go straight to configure ctdb? 2. Is the 13.1 ctdb OK? 3. Does it work in AD? 4. Do we have any openSUSE specific samba cluster stuff? Thanks, Steve -- To unsubscribe, e-mail: opensuse-ha+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-ha+owner(a)opensuse.org

[opensuse-ha] Support for the kdumpcheck STONITH plugin in HAE
by Ron Kerry 02 Apr '14

02 Apr '14

We have a customer that has requested that Novell provide full support for the kdumpcheck STONITH plugin in SLE-HAE. The plugin is documented in the SLE HAE manual in section 9.5 "Special Fencing Devices". http://doc.opensuse.org/products/draft/SLE-HA/SLE-ha-guide_sd_draft/cha.ha.… external/kdumpcheck This plug-in checks if a Kernel dump is in progress on a node. If so, it returns true, and acts as if the node has been fenced. The node cannot run any resources during the dump anyway. This avoids fencing a node that is already down but doing a dump, which takes some time. The plug-in must be used in concert with another, real STONITH device. For more details, see /usr/share/doc/packages/cluster-glue/README_kdumpcheck.txt. The plugin is also provided as part of the sle-ha pattern set of packages. However, the plugin requires a patch to mkdumprd that is not present in the SLES distribution. There is some history in SLES bugzilla associated with this plugin and mkdumprd. https://bugzilla.novell.com/show_bug.cgi?id=445870 Essentially, mkdumprd is a RHEL mechanism, so Novell will need to figure out the equivalent changes to enable use of this STONITH plugin. As it is, it is not usable despite being present and documented in the HAE Guide. Note that the real requirement here is some sort of robust mechanism to allow a crash dump to take place when HA is active with STONITH enabled. Is there some other supported way to do this? Can kdumpcheck be made to work in a SLES11 SP3 HAE environment? -- Ron Kerry -- To unsubscribe, e-mail: opensuse-ha+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-ha+owner(a)opensuse.org

[opensuse-ha] drbd and heartbeat (or others)
by Per Jessen 16 Jan '14

16 Jan '14

I'm setting up a pair of frontend nodes with a drbd device. The drbd will have LVM on top and the LVs will be shared out to other systems (backends) via iSCSI. I'm very new to drbd, although I did play with it some years ago. In order to make a node the primary, it seems I need heartbeat (or something else) to manage it? Presumably I can also add the lvm commands somehwere. The drbd website recommends pacemaker, which says it is built on corosync or heartbeat. My question is - this seems like quite a bit of work for just making sure one node is the primary, is there no simple approach? -- Per Jessen, Zürich (3.2°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse-ha+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-ha+owner(a)opensuse.org

[opensuse-ha] OpenAIS RPM missing in openSUSE 13.1?
by Thomas Schulte 26 Nov '13

26 Nov '13

Hi! Although this mailing list doesn't seem to be well-frequented, I'm hoping to get a hint here: I am (was) running a 2-node cluster with openSUSE 12.3. Pacemaker, Corosync, OpenAIS and so on. Everything was working almost fine. Today I set one node offline to migrate it to openSUSE 13.1. After successfully installing all packages and rebooting the system, I noticed that the openais RPM seems to be missing. It's not included in repo-oss, although it should be (as said on this page: https://en.opensuse.org/openSUSE:High_Availability). I switched to network:ha-clustering:Factory, but there's still no openais package found. Did the openais package got lost on it's way to openSUSE 13.1 or do I need to configure my cluster-node with different tools? I couldn't find any news about this in the release notes. Any hint is welcome. Regards, Thomas -- E-Mail: thomas(a)cupracer.de Web: http://www.mynakedgirlfriend.de

[opensuse-ha] multicast problems with cluster of KVM guests
by Tim Serong 27 Sep '13

27 Sep '13

Hi All, I spent quite some time last week bashing my head against a weird multicast problem. I have openSUSE 12.3 on my desktop, running a cluster of openSUSE 13.1 beta VMs, configured for multicast. After a while one then the other node would start spewing "corosync [TOTEM] Retransmit List: ..." to syslog, and the cluster would break. This seems to be the same issue discussed here: https://bugzilla.redhat.com/show_bug.cgi?id=880035 If anyone else hits this problem, you can work around it by running the following command on the host: # echo 1 > /sys/class/net/virbr0/bridge/multicast_querier Substitute your bride interface name for "virbr0" as appropriate. Alternately, configure the cluster to use udpu instead of multicast. I've also added this to the wiki page at http://en.opensuse.org/openSUSE:High_Availability Regards, Tim -- Tim Serong Senior Clustering Engineer SUSE tserong(a)suse.com -- To unsubscribe, e-mail: opensuse-ha+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-ha+owner(a)opensuse.org

Greetings, Welcome to opensuse-ha. This list is for discussion of high availability clustering on openSUSE. This includes: - The base cluster stack, i.e. corosync and pacemaker - Management tools such as crmsh and hawk - Clustered filesystems (e.g.: ocfs2) - Replicated storage (drbd) - Basically, anything in network:ha-clustering:* on OBS is on topic :) Please also see the wiki page at: https://en.opensuse.org/openSUSE:High_Availability Happy clustering!
