Adding Samba to an existing NFS-Cluster

Hello!
Currently we are running a cluster consisting of two nodes which provide two NFS servers (one for each node). Both nodes are connected to an 6140 Storage array. If one of the nodes fails, the zpool is mounted on the other node, all works fine. The NFS servers are started in the global zone. Here is the config of the current cluster:
# clrs status
Cluster Resources ===
Resource Name        Node Name            State     Status Message
fileserv01            clnode01            Online    Online - LogicalHostname online.
                      clnode02            Offline   Offline
fileserv01-hastp-rs   clnode01            Online    Online
                      clnode02            Offline   Offline
fileserv01-nfs-rs     clnode01            Online    Online - Service is online.
                      clnode02            Offline   Offline
fileserv02            clnode02            Online    Online - LogicalHostname online.
                      clnode01            Offline   Offline - LogicalHostname offline.
fileserv02-hastp-rs   clnode02            Online    Online
                      clnode01            Offline   Offline
fileserv02-nfs-rs     clnode02            Online    Online - Service is online.
                      clnode01            Offline   Offline - Completed successfully.Now we want to add two Samba servers which additionally share the same zpools. From what I read in the "Sun Cluster Data Service for Samba Guide for Solaris OS" this can only be done using zones, because I cannot run two Samba services on the same host.
At this point I am stuck. We have to failover both NFS and Samba services if a failure occurs (because they share the same data) and have therefore to be in the same resource group. But this will not work because the list of nodes for each service is different ("clnode01, clnode02" vs. "clnode01:zone1, clnode02:zone2").
I can mount the zpool from the global zone using "mount -F lofs", but I think I need a real dependency for the storage.
My question is: How can we accomplish this setup?

Hi,
You can run multiple Samba services on the same host or global zone in your case. For example, suppose you had smb1 and smb2, you could run smb1 within your fileserv01 RG and smb2 within your fileserv02 RG.
The only restriction is if you also require winbind, as only one instance of winbind is possible per global or non-global zone. In this regard if deploying smb1 and smb2 as above, if winbind is also required you would also need a scalable RG to ensure that winbindd gets started on each node.
Please see http://docs.sun.com/app/docs/doc/819-3063/gdewn?a=view in particular Restrictions for multiple Samba instances that require Winbind, also please note the "note" within that section, which indicates that "... you may also use global as the zone name ..."
Alternatively, please post the restriction from the docs.
Regards
Neil

  • Set samba on NFS cluster

    Hi,
    I have a two nodes cluster running HA NFS on top of several UFS and ZFS file systems. Now I'd like to have samba sharing those file systems using the same logical hostname. In this case, do I need to create a separate samba RG as the user guide suggested, or I can just use the same RG for the NFS and only create a samba resource through samba_register?
    Thanks,

    Thanks Neil for spending time on this issues on the weekend.. I should have thought about these two things when I did the testing Friday.
    I just corrected the config file and re-run the test. It still failed. I notice it complained the faultmonitor user as well as the RUN_NMBD variable.
    For the first complaint, I did verify the fmuser as the manual suggested through the smbclient command.

  • Issue in adding Space to the existing Virtual Machine from added repository

    Hi,
    I'm facing issue in adding Space to the existing Virtual Machine (Guest OS) from added repository.
    Environment details :
    VM Server : /OVS => 130GB
    /OVS/935970F2CC2D4B4391701397517F1001/ => 512 GB
    Things I have done :
    •     I created a VM (Guest OS) in the VM Server with 120 GB
    •     After creating the VM (Guest OS) , When I tried adding a VIRTUAL DISK of size 150 GB , I got an error “Maximum available Disk space is only 10GB”.
    My query :
    •     Will I be able to add space to Existing VM from the added Repository ( /OVS/935970F2CC2D4B4391701397517F1001/ ) , whose system.img is stored in path /OVS/running_pool/34_rhel/ .
    Kindly help me out in this.
    Thanks in advance.

    Hi all,
    I checked with Oracle on the above and got the info currently , the we can utilise only the space available in the existing repo and cannot extend to additional repo.
    Work around is : Clone it to the other repo , or Use Symbolic link .
    Thanks,
    Sri.

  • Adding Index server to existing farm, "Server Farm Product and Patch Status" returned 34 Missing Locally required products and patches

    Once I connected my new server to my farm's config db, it returned all of the following missing locally. I stripped out any redundancies and Headings, and I'm left with 43. I'm looking for a efficient strategy. Should I start with the lowest version number

  • Adding portal to an existing domain

    Hi I have a JSP/Servlet web applicatin and
    I want to make it a portal application.
    I was following Weblogic Portal Development
    Guide 7.0. I found the section
    "Adding portal to an existing domain" is very incomplete
    or confusing and I cannot do it. Is there any better document
    for this?

    Judging from the dates between these two entrries and no answers, I'd
    guess that there isn't anyone from BEA monitoring this group? I am in a
    similar situation. What I want to understand is how one can "portalize" an
    existing web app. I understand there are implications to some of the
    presentation, but specifically, I want to deploy a Servlet based app that
    uses EJBs and deploy this as an EAR in the same domain as the portal
    (perhaps under the /applications directory). I can make everything work
    except the webflow where I reference the Servlet.
    Specifically, I have a presentation page that is defined to be my servlet.
    When I try to build a webflow URL referencing this event, I get errors from
    the portal because it presumes it may be located somewhere else or in a
    different namespace. It leads me to believe that I can't reference a
    servlet unless it is under the /framework or /portal directories under the
    portal web-app directory. I'm convinced there must be a way to reference
    other web components that aren't specifically part of the portal web app,
    but can't figure out how to propagate the webflow element to the actual
    servlet I want.
    Any ideas from the community at large? This must be something other
    people have wrestled with since I can't imagine that only new apps will be
    put into portals.
    Thanks,
    Mark

    I'm facing similar problems too. I have an ear file in an existing domainthat

    What's BEA's recommended way to expose an existing Weblogic application asa portal

  • Adding replication to an existing database.

    I am looking at adding replication to an existing database. This database has lots of existing containers many of them are 1G in size. How will this be handled when the master and client initially start? Will the master just start sending to the client? Is there another option?

    Yes. This, and the alternatives, are described in the Ref Guide, on the page entitled "Initializing a new site".

    thanks

    The only thing you want "cloned" is the base OS install... The GI home directory, the oraInventory and a whole lot of other stuff is configured at addNode time or cluster install time. I would say that proceeding with your current plans will corrupt your clusterware. You really need to STOP LISTENING to the SA's and START reading the documentation on how to add a node to a cluster. Simply changing the hostname IS NOT a supported "feature".
    Start with a CLEAN OS. Configure shared devices, networks, /etc/hosts, memory and packages.
    Follow the instructions for addNode.
    Doing this any other way has the potential to corrupt your entire cluster.

  • Question on adding new server to existing pool in OVM 2.2 environment

    I have an existing iscsi based server pool with one server attached to the pool. I am adding a second ovm server. I have configured the iscsi and multipath modules and can see the repository lun.
    I then added the server to the pool via ovm manager, but the server is not fully participating as the agent did not create a mount point for /OVS so I can't see the repos directiories from the new server. A "df" does not show the device as it does on the first server.
    The manager gui does show the server as part of the pool even though we received an error.
    In the ovm manager log, we see the following messages.
    Check prerequisites to add server (ovm2.highlinehosting.com) to server pool (san_pool1) succeed
    During adding servers ([ovm2.domain.com]) to server pool (san_pool1), Cluster setup failed: (OVM-1011 OVM Manager communication with ovm1.domain.com for operation HA Setup for Oracle VM Agent 2.2.0 failed: errcode=00000, errmsg=Unexpected error: <Exception: ha_check_cpu_compatibility failed:<Exception: CPU not compatible! {'ovm1.domain.com': 'vendor_id=GenuineIntel;cpu_family=6;model=44', 'ovm2.highlinehosting.com': 'vendor_id=GenuineIntel;cpu_family=6;model=46'}> )
    I'm not sure why it's complaining about cpu compatibility as we are not using any HA features at this time, and both servers are identical in make and model. They are both equipped with the same cpu type and speed.
    I checked ocfs2 network connectivity by executing the command "nc -zv nodename 7777", which ran successfully from both nodes. The manager was able to propagate a valid cluster.conf file to both servers. I restarted the ovs-agent service on the new server.
    Are there any other configuration steps that I need to take on the new server before trying to add it to the pool? I do need to tread carefully as I have live guests running in the pool.
    Thx

    Bob Weinmann wrote:
    If I have to go the route of using a separate pool for each server, do you have any suggestions on how I would be able to access the repos of server1 from server2 if server1 were to go down hard? I don't mean to access it as a repos for running the vms, but just to be able to copy the vm files over to the running server.This would be possible if you were using NFS for your storage, but not if you're using FC or iSCSI, as the LUN is formatted with the OCFS2 cluster ID of each pool, so probably wouldn't be able to be mounted by another pool. Your best bet is to upgrade to Oracle VM 3.0 so that you can create a pool that contains both servers: you won't have live migration, but HA will still work just fine.

    1. just use one alter diskgroup command, rebalance would be executed just one time
    2. on node 2, do you see the disks as on node 1?
    select GROUP_NUMBER,NAME,PATH,HEADER_STATUS,MOUNT_STATUS from v$asm_disk order by name;3. try this:
    ALTER DISKGROUP DATA_GRP01
    ADD DISK '/dev/asm_disk65' name DATA_GRP01_0017,
                   '/dev/asm_disk66' name DATA_GRP01_0018
    REBALANCE POWER 5;

  • Existing SQL Cluster: Easiest Method to Move to new Datacenter

    Although there are a few questions similar to mine, I didn't find anything with these special circumstances, so I'll try a new thread:
    We have an existing SQL 2008 Cluster with shared storage in a data center and we're moving this to a new data center.  It's quite a bit of data (400GB+), and I'm looking for a way to move it over without extended downtime.  Is there a way to
    add a third node perhaps to the cluster that's read only but syncs the data?  As a systems administrator (this company just lost their DBA, so I'm short filling the role), I may be approaching this the wrong way, but anyway.
    Any ideas?
    Thanks!

    Hi VintageDon,
    According to your description, personally，if you choose to use log shipping after adding a third node, you will need to manually transfer things like logins, linked servers, SQL jobs, etc. Even if you can failover the databases and recover
    them, however, this still causes SQL Server downtime due to the bit of data. Microsoft added live migration to Hyper-V in Windows Server 2008 R2, and Windows Server 2012. The management feature helps reduce planned downtime and provides a foundation for the
    dynamic data center by allowing you to move virtual machines (VMs) between Hyper-V hosts with no downtime at all.
    A memory synchronization process occurs where the target VM is updated with the user’s changes to the source VM. After the memory is synchronized, the user is cut over to the VM running on the target Hyper-V host. The VM on the new host can immediately access
    its virtual hard disk (VHD) files stored on Cluster Shared Volumes (CSVs). For more information, see:
    http://windowsitpro.com/windows-server-2012/windows-server-2012-shared-storage-live-migration

  • Adding new fields to existing cube

    Hi all,
    We have a cube with data, now we added 2 new fields to the datasource. And want to add two more fields in the Cube to correspond to the new fields. What would be the impact on the data that is already there in the cube? Can I go ahead and add the fields in the cube and start extracting data? What I want to know is what would be the implications in such a scenario?
    Any insight or help would be appreciated and fully rewarded.
    Thanks,
    Mav

    Hi,
    At least from the experience I had there were no performance issues. The only issue would be in terms of the time taken to transport. The larger the amount of data ,longer the transport time.
    You can continue extraction of data for those 2 fields from that point on. No need to empty the data from the cube and reload again. Only thing is that the data in the past for these 2 fields may not be mapped to the existing data in the cube. If you want to do that dump the cube and reload. Otherwise the data will be mapped from the time you start extracting the new fields with the data in the cube.
    Cheers,
