Re: [Linux-HA] SAPInstance does not start and asking for START_PROFILE
Hi Muhammad, please ask the SAP Guys what they have changed. Did they install the sapstartsrv or saphostagent? Threads should not stop with its working now, but I could not explain what we have changed :) This stops others to learn from this situation.

Re: [Linux-HA] Antw: SAPInstance does not start and asking for START_PROFILE
No only in very old versions there where two different profiles. One START profile and one instance profile. Today they are combined in the instance profile. The parameter name however could not be changed without hurding all installations outside. So its ok with a current NetWeaver, if the startprofile param points to an instance profile name. However if this is a very old SAP NetWeaver than your idea the right pointer. This is also why I asked for the SAP kernel version.

Where previously you used a script to start processes, you now have some script that acts like a web client to send some request to a java-based web server that in turn is expected to start the required processes. My guess is that this is W*d*ws-style so having GUIs which are using someting like rest-APIs to provide a system change instead of just starting a well-working start script (like sapstart was in the past). Ive' see cases where a started sucessfully did not mean anything, i.e. nothing was started. OK, that was off-topic, but I had to say. Yes that's unfortunately true and that's also why we recommend tom monitor the SAP instances to figure out real start error during the next monitor cycle. So regarding compatibility, you must make sure that the configuration files and related components match hte rest of your SAP infrastructure. My favorite is this: If you run a java stack that does nothing (is idle), it takes 6 minutes to shut down the SAP instance (while there is no I/O and no CPU activity). Only the best programmers (TM) can write such code. I had to increase timeouts several times to prevent machine fencing while waiting for the stop command to complete... off-topic again, sorry.

I have simple two-node cluster with virtual ip address and Postgres with streaming replication, created with this tutorial: http://clusterlabs.org/wiki/PgSQL_Replicated_Cluster I have two problems to solve: 1. I need some script, which will restart cluster on user demand. This script should stop postgres resource on both nodes and next restart them in that way, that postgres will be work without any additional operations (like removing lock files, cleaning resources etc). 2. I have a virtual model of this cluster working under VMWare. VMWare is restarted from time to time, and I have no control when master or slave will be restarted. I would like to create script, which will be called from runlevel 6 and will safely stop postgres resource. I tried to do it with: crm configure property stop-all-resources=true but after reboot I had to remove PGSQL.lock manually, and also master node has been changed. Do you have any idea how to do it ?

2) My problem :
When there is a network problem :
Ex :
a) first-node site lost internet connection ( and communication with
second-node at same time due to vpn on internet connection )
b) cluster stop openvpn on first node and launch it on second due to primitive
p_ping in config.
c) connection come back on first-node site
d) Problem : first-node and second-node don't bring back cluster, the don't see
each other and create a cluster on each node - split brain I think.
e) Each node has openvpn running which shouldn't happen
I don't have stonith running because I think without quorum it will be
problematic
Is there a way to say to corosync to recreate a ring ?
Or have someone another solution ?

Re: [Linux-HA] Funny messages from crm resource restart (SLES11 SP2 vs. SP3)
Hi, Did you run the ha update like a rolling update, so one node with current version online, the other down. Than updating the offline node, reentering the cluster again? In this case I would think the cluster is ok but still only supports the old options. Its different from the situation'when you would restart both nodes with only one system updated. If I got it corredctly only the first method is recommended.

The new setup preferred by _SAP_ is, that you use the saphostagent. This new menthod gives you the following benefits (you might not need today) 1.

For the resource agent the only change is, that the warning disappears. If you do not find the SAP docu (SDN, installation guides) about this topic I could try to sent you an URL, but as it is SAP documentation it could be that you need a SAP marketplace login for that. The former version is still supported (and working, I trust). Yes with at least one limitation: For Java (only) workloads the there must be at least one Java instance installed on a node, where DB should be able to run (the bootstrap files of the java framework are needed for monitoring the database). When you get a chance, you should install the SAP host agent as per the reference SAP note. (Which I can't look up, it seems.) I asked the SAP Consultant to install the SAPHostAgent. Perfect! The warning does not indicate an error, but tries to get your attention about improving your configuration during the next appropriate maintenance window. It seems that worked ;-) correct, cluster never shows any error when it runs/start the SAPInstance, though we found that whenever we run the SAPInstance from cluster SAP gives us errors while login via SAP Client(SAPGui). Which error? Could it be a license problem? A standard SAP license applies to one Hardware-Key only - your SAP consultatnt should be able to solve this. as a workarround, we stopped the SAPInstance from the cluster, let the cluster runs/start the other resources(IP, File Systems, and SAPDBInstance) and then manually started the SAPInstance(via sap way): startsap -i DVEBMGS00 -v pgtprd This should not be needed - there must a something wrong - which error message did you get when SAPInstance was controlled by cluster and you login via SAPGui? If you get a SICK message about 3.0 kernel please update to a current SAP Kernel (I could provide the SAP Note number if needed).

I asked the SAP Consultant to install the SAPHostAgent issue. See also the agents documentations: crm ra info SAPDatabase I read it and found nothing that help me fix this issue. The good news is that it still works despite of the warning. The RA is a good example how to do a simple thing with maximum complexity. According to my little understanding that SAPHostAgent is a web server running as root, launching the sap start script on demand. The RA in turn sends a HTTP request to the Host Agent to start the process. I did not care to examine how authentication works, because I want to be able to sleep at night ;-) Oh you could sleep at night, even when I explain it: The autorization is made by a file permission of a socket on the system. So the Linux/Unix file permissions are controlling the permission to sent a set of commands to sapstartsrv / saphostagent. (Others could also be sent without that file permission - the set if comamnds needing authorization is controlled by a SAP configuration.) There are 3 (or more?) methods to authenticate: a) without (for simple unproblematic commands) b) via socket/file permission c) with username/password c) of course could not be used by the RA without introducing a security problem (and so does not try it :) I could not join your statement about the resource agent. The interface HOW to start/stop databases and instances is given by SAP, so the author of the RA implemented it in a SAP preferred way. The reason for the Webservice and to force also the RA is using it that the Webserver is THE interafce for all methods to control SAPDatabase and SAPInstances from outside. Its used by - SAP MMC - SAPMC - sapcontrol and maybe even by more...

In this case the SAP Kernel should be updated. as a workaround I **only** stopped the SAPInstance from cluster(let the IP, File Systems, SAPDBInstance remain running via cluster) and start SAPInstance via command line startsap -i DVEBMGS00 -v pgtprd. SAP kernel version is 701, and we are running SAP on SLES 11 SP2 via Kernel 2.6 compatibility mode for SAP (SAP note 1310037) Yes the 2.6 compatibility environment was only inteded to be used as a bridge between the avaialblibity of Linux 3.0 kernel and the customer to be able to update to newest SAP Kernels like 720 PL 402 or so. Sorry, that I couldn't solve that problem via this list, it now gets very SAP and support specific - if you have already opened a ticket at SUSE, please reference to that thread (my colleague already has read it :) and than we could help you with professional support. In sum its that SAP also wants you to update to the newer SAP kernels and my guess is that this is exactly your problem. While starting/stopping the instance with login-user/shell will lead into the 2.6 compat environment, the RA still runs in 3.0. == solution is either to change one line in RA (NOT preferred) or to update SAP kernel to current version (very appreciated and preferred :) Regards, Muhammad Sharfuddin ___ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.19 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJRf8Y0AAoJEJ1uHhrzMvZR9/QIAIKZs1RyGLfZZ9aUlJZR7EGM V7thYcSldUGn0HivtW9N+kufxJHfapJ70L1o9wAw0kTbq5CaVgt42B177zB4Kq3q 5q6db1ouDh7ZufV+6Dprhff8mplEMrTCJKDPjYnna7COYzkWYPun2FBNPmAV1pGs rBmxDBH9enZ5Piacj357Rqqs2mFhmnBeSDOIDDqMX8BBG+MIuslYOoBfyzwUTilv ECJnkAHQZcT9CsRJ6wLkQCfFSD+HzpGp3tLZhYxi9ub7SPlthCI8vJOgp5HZhbLp SvR9SCp3RG71+HLWKuCBd+u/JWDuymFnZ8jIoyUDWFVJRdkT59jsha2T2qIqbRI= =nIwo -END PGP SIGNATURE- ___ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems

Unfortunately at least for SAP Workloads this is not an option, because all Instances must be killed to switch from a bind mount to an NFS mount and vice versa. This would decrease the availability of the Application level. The problem are already opened file handels which can't be shifted from the bind-Mount to the NFS-mount. For all files and directories which are only opened after the FS switch that might be OK, but again that would also mean to kill all application processes using the FS. I do not see that this would be a fissible solution. Kind regards Fabian ? Now when som program does a cd mountpoint and the NFS Server would move to another host, you'd have to kill all processes that use mountpoint to be able to unmount it. In contrast with the NFS solution, the client applications would be blocked until NFS server is running on the other node. Obviously this solution seems preferrable.

Re: [Linux-HA] why nodes cant see each other ?

As you are using Multcast (MCAST) - could it be the case that the
switch/LAN dropped all Multicast packages for some time? As lot of
switches which are managed are dropping MCAST by default (at least
I got that feedback from customers) it could be that your switch was
either reconfigured for a time period or there was a fireware update?
Just my thoughts abou things happened at customer side.

You might check the scoring if the resources after you have killed one side and check it with ptest -Ls (or an matching other call without ptest - sorry I do not remember the other comamnd). On SLES pstest -Ls will show you the scores in the Live situation and if crm_master is used it also will show you promote-scores.

Re: [Linux-HA] Setting up HA-Cluster with heartbeat and SAP
Do you still really need heartbeat v1???
There are some advanced SAP Resource-Agents for heartbeat v2, which
also include monitoring and service restarts.
The problem with your own(?) RA is it could damage your data, if the
unmounts are not work properly (failing due to open files). This could
cause dual mounted file systems - ugly!

[Linux-HA] Re: Configurating STONITH device (how to avoid reset each other)
Hi, for heatbeat 2.1.4 there is IMHO no out-of-the-box solution for that problem. I dont know, if the following method would be a valid method: Edit(!) the stonith script and add a sleep XX to the one of the nodes stonith script. This would cause one of the script to hang for some seconds. In consequence the resulting stonith actiond should not appear at the same time. Hopefully this does not work against haertbeat internal sleeps (did not test that so far). This method also causes, that teh cluster takeover action will run some seconds later (on the changed node), because the stonith action has to be fullfilled before other actions could be processed. @List: Would that be a valid work-arround?

Re: [Linux-HA] Heartbeat 2: failover of EVMS private container resources
Hi, please try either lower-cased host/node names or use the patch I sent yesterday. The problem is that heartbeat uses the lower-cased hostnames as nodenames and membership list in the CCM. EVMS compares case-sensitive. This means evms says your cluster node acquiring the private container is not allowed to do it, as the CCM has not the exact node name in its list. In you case the node names (CZVLabNode2) is not lower cased this is the cause of the problem. Either change both nodes to lower cased (uname -n must report correctly, hostname also), or apply the patch. After that you should use the following procedure to come out of the stored failuers of the evms_failover resource: 1. Cleanup the resource 2. Stop(!) the resource 3. Start the resource If the resource belongs to a group finaly delete the target_role of the evms_failover resource. Now everything should work fine. Best regards Fabian Am Freitag, den 23.11.2007, 11:16 +0100 schrieb Chris: Hi Yan, Thanks a lot for your help. I took out the evmsSCC resource from the scenario, but I did not see any difference in the system behavior, then I followed your suggestion and I manually tested the EVMS commands from the CLI while both the nodes where in stand-by, and I actually realized that the command: modify: gwcont,type=private,node=CZVLabNode2 was failing; was somehow not recognized as a valid command. The really weird thing is that the same command, avoiding the capital letters in the host name, was successful: modify: gwcont,type=private,node=czvlabnode2 This was true in both nodes, so I modified both the hostnames from: CZVLabNode1 -- czvlabnode1 CZVLabNode2 -- czvlabnode2 and now the fail over is working properly. like everything else. The reason why I tried to change the host names so to avoid any capital letter is that I noticed that, even if my host names were a mixture of normal and capital letters, in the hb_gui they were shown without capitals. As soon as I will have time for this, I will do some further test to verify if I can duplicate this again starting from scratch, so to verify if Heartbeat 2.1.2 and/or EVMS 2.5.5.-24.52 really have some issues with node names partially capitalized, I will update the list afterwards. Could also be that I modified something else in the system that I'm not fully aware of, or I simply or forgot it, as I did many different test on the same boxes.

I believe so... have you read the documentation below? http://wiki.novell.com/images/3/37/Exploring_HASF.pdf In my lab I can only start and stop the resource on the node that has the container assigned within evms, while if I shut down that node, the fail over does not occur as the evms_failover resource goes in time out; as soon as the other nodes comes up again it takes the resource back properly. This would indicate that evms_failover RA cannot assign the container to the new node. Do you see the resource failing? Have you checked failcount for the resources on that node? Some clues (from evms perspective): take a look in /dev/evms/.nodes When the private container is present on the node, a device file named after the container should appear there. TO test manually, the easiest is to start HB, then put both nodes on standby, then manipulate the evms devices manually. To deport the container (on resource stop) evms_failover issues commands to the evms command line tool: modify:$1,type=deported save exit where $1 is the value of the 1 parameter you've passed to evms_failover. You can try this yourself manually, to verify where the issue is (i.e. with evms or elsewhere). To import the container (when starting the resource), evms_failover does: modify:$1,node=$HOSTNAME,type=private save exit In my environment I created the following: I'm working using 2 VMWare boxes sharing one 4GB plain disk that works as SAN; EVMS: I created a private container (gwcont) on the shared disk using CSM plug-in and in it an EVMS Volume (gwvol); on the volume i make a reiserfs file system; I verified that the HA plug-in was working and that the node assigned to the container can manually mount it.

Am Freitag, den 30.11.2007, 12:19 + schrieb Yan Fitterer: First question: Are you interested in my patch (just 2-3 lines)? Most likely ;) Although I'm not completely sure how case is handled elsewhere. We might be case-sensitive on purpose! (although I can't see a good reason to do this for host names). Heartbeat handels case-sentive hostnames by lowercasing them. Thus the CCM only lists lowercased hostnames (see crm_mon, gui and others). But the nodes in ha.cf should written like uname -n responds (which is in oroginal letters thus with case. The problem using the evms-failover resource agent is that the hostname is given to evms in original (case sensitive) letters, evms check the string case sensitive (here is the original error I guess) against the CCM entries and claims, the parameter is illeal (evms means the hostname is not member of teh cluster, wile heartbeat says it is member of the cluster (just different string comparing). My patch just ignores upper/lowercases by lowercasing the local hostname. This seams to be compatible with the way heartbeat is doing it. And it is (fow now) much more easy to handle (for me) than to change the evms behaviour. Hope the patch is helpful Fabian Maybe send to the -dev list? Sorry I am not assigned to the dev list. So first I send the (very small) patch here. See attachment (only three line patch). Second: Any idea why I am not able to migrate the private container? Are there any typical pitfalls? The resource cannot run anywhere is nothing to do with the resource agent. It's the PE (Policy Engine) deciding that it is so. Likely you have either resource node failcounts that are too high, or failed starts. Resources that have failed to start on a node are not eligible to be started again on that node (at least on the SLES 10 2.0.8 version). I've heard this may change one day. To see failed starts, try crm_verify -VV To see failcounts, I usually grep the output of cibadmin -Q (much faster than issuing multiple crm_failcount commands...).

[Linux-HA] evms-failover resource agent does not handle case sensitive hostnames correctly
Hi, I have searched for some times, why my defined evms-failover resource does not work on any of my heartbeat 2.0.8 nodes (SLES10SP1, x86_64). I want to use a private evms container to avoid the (noc cluster) file system to be mounted twice by administrative error. But the resource was not started on any node. So I checked, what the re source agent have to do to start an private container resource and tried to do that by hand using the CLI. The CLI everytime told me a parameter was wrong (but not any useful information which parameter). Then I tried to aquire the private container but used the lower cased hostname (not the hostname sean running uname -n) and it worked. I wrote a small patch for that resource agent and than teh resource could be started on one cluster side but could not be migrated. The cluster says the resource xxx could not run everywhere.
