This is a way +to refer to multiple resources at once without creating any +colocation or ordering relationship between them. For example, you +could add all resources related to the database to a db tag, and +then stop or start them all with a single command. + +---- +tag db drbd:Master fs sql-db +---- + +It is also possible to refer to tags in constraints. + +== Wildcards in show/edit + +The configure show and edit commands can now use glob-style +wildcards to refer to multiple resources: + +---- +configure edit db-* +---- + +== Nvpair references + +Sometimes, different resources name the same parameters with different +names. For example, an IPAddr2 may have an ip parameter that should be +the same as a web servers server_ip parameter. By using nvpair +references, it is possible to configure the ip in a single location. + +Note that this is a new feature in Pacemaker 1.1.12 and up. + +---- +primitive vip IPAddr2 params $my-ip:ip=192.168.0.1 +primitive www apache params @my-ip:server_ip +---- + +== New ACL syntax + +The support for Access Control Lists has been revised in Pacemaker +1.1.12, and this release of crmsh supports the new syntax. Two new +commands have been added: `acl_target` and `acl_group`. For more details, +see the documentation. + +Thank you, + +Kristoffer and Dejan + |
