steeleye-lkHOTFIX-systemd-PL-6728-9.5.1-7154.noarch.rpm

Patch availability: General Availability
Product (s) Supported: This patch is valid only on LifeKeeper v9.5.0 and v9.5.1 running RedHat, CentOS or OEL OS versions (SLES is excluded as no issue exists on that OS platform).

NOTE: This patch must be removed before upgrading LifeKeeper to a newer version beyond v9.5.1


Issue(s) addressed by this patch:
PL-6728 - 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.


Patch description:
This patch provides the following improvement to the lifekeeper.service:

1) This patch prevents systemd from stopping the NFS subsystem before LifeKeeper stops.
