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 LifeKeeper 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.

Bug Fixes
The following is a list of the latest bug fixes and enhancements.
| PL-4739 | Fixed a bug that could cause /etc/default/LifeKeeper to be 0 bytes after forced shutdown. |
| PL-7770 | The lklicmgr utility now shows the correct description for an SAP HANA Recovery Kit license. |
| PL- 9226 | Fixed an issue where /dev/vgname/lvname could not be specified as a device in DataKeeper resource operations using LKCLI. |
| PL-9280 | The SAP Recovery Kit will now log an error message if it detects that a protected ERSv1 instance is running on multiple cluster nodes. |
| PL-12315 | The LifeKeeper startup will now start after the AWS cloud-init process completes. |
| PL-12620 | When using storage quorum functionality in ‘aws_s3’ mode, qwk_storage_init now verifies that s3:GetObject permissions are granted. |
| PL-12621 | When using storage quorum functionality in ‘aws_s3’ mode, an error message is now logged when the S3 object becomes inaccessible. |
| PL-12623 | When using storage quorum functionality, an error message is now logged when the QWK object of the remote node has size 0 bytes. |
| PL-12624 | In a situation where errors are continuously occurring while reading/writing a QWK object, repeated error messages of the same type are suppressed from being output to the log file. This prevents the log file from being filled with the target error message and makes it easier to identify the problem. |
| PL-12625 | A message is now logged when the acquisition status of a QWK object changes. |
| PL-12934 | The SAP and SAP HANA Recovery Kits will now detect the appropriate NFS version and protocol for a required shared file system without requiring the user to manually add entries to the /etc/default/LifeKeeper file. |
| PL-12940 | When the QWK object storage type is “block”, log an error if the device node does not exist. |
| PL-13141 | Storage quorum (qwk_storage_init) error messages are now easier to understand. |
| PL-13245 | Emergency log messages from LifeKeeper may now be temporarily disabled by setting appropriate LifeKeeper flags. |
| PL-13248 | When an IP address has been manually associated to a network interface using the wrong network mask, the IP Recovery Kit will now log an error when bringing the resource in-service and successfully remove the IP address when bringing the resource out of service. |
| PL-13260 | Fixed a memory leak related to the lkvmhad process. This is a VMware only issue. |
| PL-13355 | Users are now notified via email and/or SNMP when a DataKeeper mirror resynchronization completes. |
| PL-13460 | The LifeKeeper GUI now correctly shows the process names in the resource properties panel for an SAP Recovery Kit resource protecting an ERSv1 instance. |
| PL-13589 | Fixed an issue where an SAP resource may fail to come in-service after a machine failover if there is a running process on the new host server whose PID conflicts with PIDs stored in the sapstart.log file. |
| PL-13748 | Oracle Linux 8.5 RHCK users can now use DataKeeper without additional steps. |
| PL-13953 | Fixed bug in LB Health Check Kit where Gen LB restore failed if Gen LB daemon is already running. |
| PL-14238 | Fixed bug in LB Health Check Kit where Gen LB’s check_exist_process could fail to reboot in some cases. |
| PL-14247 | Fixed bug in LB Health Check Kit where lkstop -f also stopped the Gen LB daemon. |
| PL-14388 | Disable LVM auto_activation_volume_list in lvm.conf to allow the SCSI check daemon to open/close the device without causing a failure. |
| PL-14401 | The NetworkManager-initscripts-updown package is installed with LifeKeeper on RHEL8.6 or later. |
| PL-14795 | QSP can now protect Samba and Postfix services. |

Note: This patch must be removed before upgrading LifeKeeper to a newer version beyond v9.6.2 |
| steeleye-lkHOTFIX-NFS-PL-12327-9.6.2-7477.noarch.rpm | NFS resource hierarchy switchover hangs when exportfs hangs. | This patch will wait up to 30 seconds for the exportfs command to complete before aborting the action. A notification will be provided to the user that the process appears to have hung and may require a system reboot to clear the hang. |

See the LifeKeeper for Linux Installation Guide for complete installation and configuration information.
Upgrades
LifeKeeper can be upgraded to Version 9.6.2 from either LifeKeeper Version 9.4.x, Version 9.5.x or Version 9.6.x. If upgrading from a version other than 9.4.x or 9.5.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 9.4.x or 9.5.x, then perform the upgrade to 9.6.x.
