- Ubuntu HA - Pacemaker Resource Agents Supportability
- Resource Agents: main Agents in this list are supported just like any other package available in main repository
– lvmlockd can work with lvmetad.
Note: targetcli-fb (Linux LIO) will likely replace tgt in future Ubuntu versions. Upstream Documentation The server guide does not have the intent to document every existing option for all the HA related softwares described in this page, but to document recommended scenarios for Ubuntu HA Clusters. You will find more complete documentation upstream at: • ClusterLabs – Clusters From Scratch – Managing Pacemaker Clusters – Pacemaker Configuration Explained – Pacemaker Remote - Scaling HA Clusters • Other – Ubuntu Bionic HA in Shared Disk Environments (Azure) A very special thanks, and all the credits, to ClusterLabs Project for all that detailed documen- tation. Ubuntu HA - Pacemaker Resource Agents Supportability After discussions among Ubuntu Developers, it was decided that Ubuntu project should focus in splitting all existing Pacemaker Resource Agents into different categories: • Resource Agents: main • Resource Agents: [universe] 272 • Resource Agents: [universe]-community • Resource Agents: [non-supported] • Resource Agents: [deprecated] Note: There is a current plan to split resource agents into different packages so supported agents can be installed independently. Resource Agents: main Agents in this list are supported just like any other package available in main repository would be. | RESOURCE AGENT | RESOURCE AGENT DESCRIPTION | | SUPPORT AGENTS |Delay|test resource for introducing delay| |MailTo|sends email to a sysadmin whenever a takeover occurs| |ClusterMon|runs crm_mon to a html page from time to time| |HealthCPU|measures CPU idling and up- dates #health-cpu attr| |HealthIOWait|measures CPU idling and updates #health-iowait attr| |HealthS- MART|measures CPU idling and updates #health-smart attr| || SERVICES (OCF, Systemd, SysV) | |apache|apache web server instance| |dovecot|dovecot IMAP/POP3 server instance| |dhcpd|chrooted ISC dhcp server instance| |mysql|MySQL instance| |mysql-proxy|MySQL proxy instance| |pgsql|pgsql database instance| |named|bind/named server instance| |nfsnotify|nfs sm-notify reboot notifications daemon| |nf- sserver|nfs server resource| |exportfs|nfs exports (not the nfs server)| |nginx|Nginx web/proxy server instance| |postfix|postfix mail server instance| |rabbitmq-cluster|cloned rabbitmq cluster instance| |remote|pacemaker remote resource agent| |rsyncd|rsyncd instance| |rsyslog|rsyslogd instance| |slapd|stand-alone LDAP daemon instance| |Squid|squid proxy server instance| |vsftpd|vsftpd server instance| | | STORAGE |Raid1|software RAID (MD) devices on shared storage| |iscsi|local iscsi initiator and its conns to targets| |iSCSILogicalUnit|iSCSI logical units| |iSCSITarget|iSCSI target export agent (implementation: tgt / lio)| |LVM|LVM volume as an HA resource| |LVM-activate|LVM activation/deact work for VGs (lvmlockd+LVM- activate OR clvm+LVM-activate)| |Filesystem|filesystem on a shared storage medium| |symlink|symbolic link| |ZFS|ZFS pools import/export| || LOCKING & RESERVATIONS |controld|distributed lock manager for clustered FSs| |clvm|clvmd daemon (cluster logical vol manager)| |lvmlockd|agent manages the lvmlockd daemon.| |mpathpersist|SCSI persistent reservations on mpath devs| |sg_persist|master/slave resource for SCSI3 reservations| || NETWORKING |Route|network routes| |iface-bridge|bridge network interfaces| |iface-vlan|vlan network interfaces| |IPaddr2|virtual IPv4 and IPv6 addresses| |ipsec|ipsec tunnels for VIPs| |IPsrcaddr|preferred source address modification| |IPv6addr|IPv6 aliases| |conntrackd|conntrackd instance| |SendArp|send gratuitous ARP for IP address| |VIPArip|virtual IP address through RIP2| |ifspeed|monitor action runs -> updates CIB with if speed| || 273 VIRTUALIZATION |VirtualDomain|manages virtual domains through libvirt (virtual machine only)| || CONTAINERS |lxc|allows LXC containers to be managed by the cluster| Download 1.27 Mb.
