Description

A new script to be used in Pacemaker to manage ZFS pools and Lustre targets.

This RA is able to manage (import/export) ZFS pools and Lustre Target (mount/umount).

pcs resource create <Resource Name> ocf:heartbeat:LustreZFS \ 
pool="<ZFS Pool Name>" \
volume="<ZFS Volume Name>" \
mountpoint="<Mount Point" \
OCF_CHECK_LEVEL=10

where:

• pool is the pool name of the ZFS resource created in advance
• volume is the volume name created on the ZFS pool during the Lustre format (mkfs.lustre).
• mount point is the mount point created in advance on both the Lustre servers
• OCF_CHECK_LEVEL is optional and enable an extra monitor on the status of the pool

This script should be located in /usr/lib/ocf/resource.d/heartbeat/ of both the Lustre servers with permission 755.

The script provides protection from double imports of the pools. In order to activate this functionality is important to configure the hostid protection in ZFS using the genhostid command.

Default values:

• no defaults

Default timeout:

• start timeout 300s
• stop timeout 300s
• monitor timeout 300s interval 20s

Compatible and tested:

• pacemaker 1.1.13
• corosync 2.3.4
• pcs 0.9.143
• RHEL/CentOS 7.2
