If there is information in the sbdutil -v view from old nodes that have been removed from the cluster, you can run sbdutil -i to initialize the view. Enter nssmu to open the NSS Utility, then select Software RAIDS. Select the software RAID 1 for the SBD partition you want to delete. However, it does no harm to verify that the NCS: Shared Disk Flag attribute is enabled. have a peek here
To avoid this double fencing, add the pcmk_delay_max parameter to the configuration of the STONITH resource. Stop Novell Cluster Services by entering the following on each node: rcnovell-ncs stop Delete the mirrored software RAID that you used for the SBD partition. For example: On HP hardware, this is the hpwdt driver. For systems with an Intel TCO, the iTCO_wdt driver can be used.
Limitations Again, the sbd device must not use host-based RAID. However, YaST | \ Partition Manager has this in its table: /dev/evms/CLSTR_TEST Can't activate the pool with either nssmu or iManager. You can initialize the device by using NSSMU or the Storage plug-in to iManager. Starting the SBD Daemon The SBD daemon is a critical piece of the cluster stack.
mason ! Select the member segment you want to delete, then select Delete to remove the segment. Should you wish to try reattach to the device right now, you can send a SIGUSR1 to the SBD parent daemon. A.4.3 Return Value If the command succeeds, it prints the partition name to the screen and returns "0".
The file /var/log/messages has lines like this: [Date+time] oesclstr2 kernel: Pool "CLSTR_TEST" - MSAP activate . . . [Date+time] oesclstr2 kernel: pool "CLSTR_TEST" - Watching pool. . . . [Date+time] oesclstr2 If necessary, you can use fdisk to set the sectors for the device (such as /dev/sdx) to 32: fdisk -H 64 -S 32 /dev/sdx Home Skip to Content Attachmate Borland Micro During the 'Cluster Services (NCS) Configuration' step, I am unable to create an SBD parition. You can use fdisk to check for valid CHS values before you initialize and share the device.
If you need to re-create the SBD for a cluster, delete its existing SBD first. Before you start, make sure the following requirements are met: IMPORTANT: Requirements The environment must have shared storage reachable by all nodes. If the SBD partition is mirrored, you delete the software RAID device instead of deleting the two partitions separately. You cannot present an existing NSS software RAID 1 device to the utility.
You can create a mirrored SBD by supplying more than one device with multiple instances of the -d option. Upon receipt of a message, the daemon immediately complies with the request, such as initiating a power-off or reboot cycle for fencing. This can be done without any issues while the cluster is running. -v View the SBD partition. -d
While using nssmu to create a clustered pool on it, 'Error 20896 Operation on a shared device is rejected' always appears. http://juicecoms.com/failed-to/failed-to-find-listtemplate-tag-corresponding-to-id.html If you change the timeout for watchdog, the other two values (msgwait and stonith-timeout) must be changed as well. NSS prefers at least 32 sectors per track. For more information refer to the man page modules-load.d.
If you need to specify multiple devices here, use a semicolon to separate them (their order does not matter): SBD_DEVICE="/dev/sbd;/dev/sde;/dev/sdc" If the SBD device is not accessible, the daemon will fail Linux High Availability Clustering is needed to ensure the availability of mission critical resources. The High Availability Extension uses the SBD daemon as software component that feeds the watchdog. http://juicecoms.com/failed-to/failed-to-reboot-client-to-recovery-partition.html Is it possible to do it through the gui?
run: /opt/novell/ncs/bin/sbdutil -c -n Test_Cluster -d sda -d sda NCS install failed to create SBD partition I get no error when I create the cluster without specifying the 'Optional device for Select (enable) the NCS: Shared Disk Flag check box, then click OK. However, SBD will not fence the other side while only one mirror leg is available, since it does not have enough knowledge to detect an asymmetric split of the storage.
About 4 MB of space that is used to store its shareable state information. The software component (usually a daemon) regularly writes a service pulse to the watchdog—if the daemon stops feeding the watchdog, the hardware will enforce a system restart. Besides being a trainer, he is also an author, having written more than 20 books and hundreds of technical articles. Content is available under Creative Commons Attribution-Share Alike 3.0.
I've got two computers running OES Linux. Stop Novell Cluster Services by entering the following on each node: rcnovell-ncs stop As the root user, enter the following at the terminal console of a Linux cluster server: sbdutil -c Tks n rgds, Richard White Mason County, Washington Reply With Quote « Previous Thread | Next Thread » Bookmarks Bookmarks Twitter Facebook Google Digg del.icio.us StumbleUpon Posting Permissions You may not http://juicecoms.com/failed-to/failed-to-collect-inventory-for-virtual-i-o-server-in-partition.html as did the SBD partition. (Go figure.) So now I used nssmu to create the pool on the shared drive.
Each side believes the other has failed, and forms its own cluster view that excludes the nodes it cannot see. Please try the request again. The shared storage segment must not use host-based RAID, cLVM2, nor DRBD*. págs.168 páginas  Exportar citaçãoBiBTeXEndNoteRefManSobre o Google Livros - Política de Privacidade - Termosdeserviço - Informações para Editoras - Informar um problema - Ajuda - Sitemap - Página inicial doGoogle [prev in list]
Otherwise, no partition name is printed out, and a non-zero error code is returned. IMPORTANT:If a cluster SBD partition already exists, do not create another one. Modern systems support a hardware watchdog that needs to be tickled or fed by a software component. Delete the SBD partition.
If you have more than one node in the cluster, use one of the following methods to create a new SBD partition: Section 9.14.3, Creating a Non-Mirrored Cluster SBD Partition Section You must also initialize and share a second device if you plan to mirror the SBD. In this case, there are two cluster partitions, one with quorum because of being the majority (B, C), and one without (A). SBD Fencing From Linux-HA Jump to: navigation, search Contents 1 Requirements 2 Configuration 2.1 How many devices should I use? 2.1.1 One device 2.1.2 Three devices 2.1.3 Two devices 2.2 Initialize
You can initialize the device by using the Novell Storage Services (NSS) Management Utility (nssmu(8)) or the Storage plug-in to iManager. You might also need to delete and re-create an SBD partition if the SBD becomes corrupted or its device fails. Stop Novell Cluster Services by entering the following on each node: rcnovell-ncs stop Delete the SBD partition. You can check the output with sbd: sbd -d /dev/SDB dump ==Dumping header on disk /dev/sdb Header version : 2.1 UUID : 619127f4-0e06-434c-84a0-ea82036e144c Number of slots : 255 Sector size :
If you want to use more than one device for SBD, provide the devices by specifying the -d option multiple times, for example: sbd -d /dev/SBD1 -d /dev/SBD2 -d /dev/SBD3 create Make the best start with HA clustering with Pro Linux High Availability Clustering at your side. This can be connected via Fibre Channel, Fibre Channel over Eterhnet, or even iSCSI. This configuration is suitable for more complex scenarios where storage is not restricted to a single array.
