Large
Cluster
Support
LifeKeeper supports large cluster configurations, up to 32 servers. There are many
factors other than LifeKeeper, however, that can affect the number of servers
supported in a cluster. This includes items such as the storage interconnect and
operating system or storage software limitations. Refer to the vendor-specific
hardware and software configuration information to determine the maximum
supported cluster size.
International-
ization and
localization
LifeKeeper for Linux v5.2 and later does support wide/multi-byte characters in
resource and tag names but does not include native language message support.
The LifeKeeper GUI can be localized by creating locale-specific versions of the
Java property files, although currently only the English version is fully localized.
However, many of the messages displayed by the LifeKeeper GUI come from the
LifeKeeper core, so localization of the GUI will provide only a partial solution for
users until the core software is fully localized.
See also Language Environment Effects under Restrictions or Known Issuesfor
additional information.
LifeKeeper
MIB File
LifeKeeper can be configured to issue SNMP traps describing the events that are
occurring within the LifeKeeper cluster. See thelk_configsnmp(8)man page for
more information about configuring this capability. The MIB file describing the
LifeKeeper traps can be found at/opt/LifeKeeper/include/LifeKeeper-MIB.txt.
Watchdog
LifeKeeper supports the watchdog feature. The feature was tested by SIOS
Technology Corp. on Red Hat EL 5.5 64-bit, Red Hat EL 5.6 32-bit and Red Hat EL
6 + softdog.
STONITH
LifeKeeper supports the STONITH feature. This feature was tested by SIOS
Technology Corp. on SLES 11 on IBM x3550 x86_64 architecture and RHEL5.5
64-bit.
XFS File
System
The XFS file system does not use the fsck utility to check and fix a file system but
instead relies on mount to replay the log. If there is a concern that there may be a
consistency problem, the system administrator should unmount the file system by
taking it out of service and run xfs_check(8) and xfs_repair(8) to resolve
any issues.
IPv6
SIOS has migrated to the use of the ip command and away from the ifconfig
command(for more information, see theIPv6 Known Issue).
