SIOS Product Descriptions
LifeKeeper for Linux
The LifeKeeper product includes fault detection and recovery software that provides high availability for file systems, network addresses, applications and processes running on Linux. LifeKeeper supports the configuration and switchover of a given application across multiple servers. The servers on which the application is configured are assigned priorities to determine the sequence in which the application will move from server to server in the event of multiple failures.
LifeKeeper for Linux provides switchover protection for a range of system resources. Automatic recovery is supported for the following resource types:
- Processes and Applications
- Shared Storage Devices (Including VMWare virtual hard disks)
- File Systems (ext3, ext4, vxfs, xfs and nfs) Note: btrfs is not currently supported by the SIOS Protection Suite for Linux. For detailed information see LifeKeeper Core – Known Issues / Restrictions.
- Communication Resources (TCP/IP)
- Database Applications
DataKeeper for Linux
The SIOS DataKeeper product:
- Provides volume-based synchronous and asynchronous data replication.
- Integrates into the LifeKeeper Graphical User Interface for administration and monitoring.
- Automatically resynchronizes data between source and target servers at system recovery.
- Monitors the health of underlying system components and performs local recovery in the event of failure.
- Allows manual resource switchovers and failovers of mirrored volumes.
- Can be easily upgraded to provide high availability clustering and automatic failover and recovery using a license key to enable new functionality.

|
Install | The -s option for saving the current setup configuration has been added to the setup command. |
RHEL7.6 also does not support DataKeeper’s asynchronous mode. The warning message is output by setup. | |
DataKeeper | Wait For Previous Source for multi-target mirrors. For a multi-target mirror DataKeeper keeps track of the last server, aka previous source, that had the mirror in-service. When there is a failover, the bitmap from the previous source is required to keep all of the targets in-sync. DataKeeper will now automatically wait for the previous source to join the cluster before resuming replication to any target. This allows the bitmap from the previous source to be merged so that only partial resyncs are necessary. |
Unnecessary synchronization is avoided in the environment with three or mode nodes. | |
Add updated messages for “wait for source” in GUI and mirror_status. | |

Hot Fixes and Add-on Support Packages
The patches are located here.
steeleye-lkHOTFIX-SAP-PL-6050-9.5.0-7075.noarch.rpm | Split brain created during comm_up processing when migrating the ERS hierarchy. | This patch prevents ERS hierarchy migration during LifeKeeper comm_up processing. With ERS v2 the goal is to have the ERS hierarchy running on a non-central services node but can run on the same node when a viable node is not available. When a viable target becomes available LifeKeeper will migrate the ERS hierarchy to the available target. In certain circumstances the migration would overlap with comm_up actions resulting in a split brain. This patch prevents that overlap from occurring. NOTE: This patch must be removed before upgrading LifeKeeper to a newer version beyond v9.5.0 |
steeleye-lkHOTFIX-systemd-PL-6728-9.5.1-7154.noarch.rpm | Addresses a possible hang when stopping LifeKeeper during a system shutdown or reboot. LifeKeeper depends on the NFS service in some configurations and if that service is stopped by systemd before LifeKeeper completes its shutdown a hang can occur. This patch updates the lifekeeper.service file to add a dependency on NFS to ensure NFS shuts down after LifeKeeper. | This patch prevents systemd from stopping the NFS subsystem before LifeKeeper stops. |
steeleye-lkHOTFIX-core-PL-6780-9.5.0-7075.x86_64.rpm | lkscsid core dumps: segmentation fault | This patch addresses a bug in the LifeKeeper core SCSI recovery kit where lkscsid will not properly handle the threads it starts to check devices. New threads are created instead of reusing those already started. These threads will eventually cause the process/system to run out of file descriptors and will eventually core dump. |
steeleye-lkHOTFIX-core-PL-6847-9.5.0-7075.noarch.rpm | Resource hierarchy ends up out of service on all nodes after rebooting the source node. | This patch prevents the quorum_isp logic from running on comm up events to a node for which no resource equivalencies exist. This prevents a hierarchy migration from being attempted incorrectly. Other hotfix interactions: On systems with the SAP ARK installed the hotfix rpm steeleye-lkHOTFIX-SAP-PL-6050-9.5.1-7154.noarch.rpm must be installed prior to this patch and removed after removing this patch. For more information and to download the PL-6050 patch go to the ftp link http://ftp.us.sios.com/pickup/SAP-rpm-PL-6050. |
steeleye-lkHOTFIX-IP-PL-7858-9.5.0-7075.noarch.rpm | The physical IP address is set to 0.0.0.2/0 via a restore or recover of a protected virtual IP address when the restore or recover occurs after running the command “ifdown “ where is NIC on which the virtual IP resource is attached. | This patch prevents the physical address from being set to 0.0.0.2/0 during a restore or recover of a virtual IP resource. The incorrect setting of the physical IP address only occurs if the command “ifdown “ is run prior to the restore or recover operation. |
HOTFIX-PL-9146-raid1_data_integrity_patch/ | The md/raid1 kernel driver that causes failed writes not to be reported. As a result, DataKeeper was unable to rewrite the failed data blocks when a mirror was resynchronized, causing the target to be out of sync with the source. |

Client Platforms and Browsers
The SPS web client can run on any platform that provides support for Java Runtime Environment JRE8 update 51. The currently supported browsers are Firefox (Firefox 51 or earlier) and Internet Explorer running on Linux, Windows Server 2008 R2, Windows Server 2012 R2, Windows Server 2016, Windows 7, Windows 8 or Windows 10 with JRE8 update 51. Other recent platforms and browsers will likely work with the SPS web client, but they have not been tested by SIOS Technology Corp. In addition, particular features of each browser have not been tested.
You should specify all the hostnames and addresses in your cluster in the client machine’s local hosts file (usually /etc/hosts or C:\windows\system32\drivers\etc\hosts). This minimizes the client connection time and allows the client to connect even in the event of a Domain Name Server (DNS) failure.
Installation and Configuration
See the SIOS Protection Suite Installation Guide for complete installation and configuration information.
Upgrades
LifeKeeper can be upgraded to Version 9.5.x from either LifeKeeper Version 9.3.x or Version 9.4.x. If upgrading from a version other than 9.3.x or 9.4.x, the older version will need to be uninstalled and SIOS Protection Suite for Linux will have to be reinstalled. An alternative to uninstalling the older version would be to upgrade from the older version to 9.3.x or 9.4.x, then perform the upgrade to 9.5.x.
Storage and Adapter Options
For a list of the disk array storage models and adapters currently supported by SPS in shared storage configurations as well as their type of certification, see the Storage and Adapter Options topic. Details about driver versions and other configuration requirements for these arrays and adapters are listed in the Storage and Adapter Configuration topic.
Technical Notes
We strongly recommend that you read the Technical Notes section concerning configuration and operational issues related to your SPS environment.
Known Issues
See Known Issues and Restrictions in the Troubleshooting section of SIOS Protection Suite for Linux Technical Documentation and the DataKeeper Troubleshooting section.
