removing a service from service guard

[lawrenzo]

Hi all,

I dont have much experience with service gaurd and was looking for some assistance ....

does anyone have the procedure for removing an application / service from the configuration.

basically we have a server that is no longer on the network that was part of the cluster.

Many Thanks

Chris.

Hi Lawrenzo

cmdelete conf command helps you

cmdeleteconf - Delete either the cluster or the package configuration


Please look at man page

hi Chris,

This process can be performed on a running cluster if ServiceGuard A.10.10 or
later is the current version running. If older than version A.10.10, the
cluster will need to be halted before performing the cmapplyconf step.

1) Halt the package
# cmhaltpkg


2) For clusters running ServiceGuard version 10.10 and newer perform:

# cmdeleteconf -p

For ServiceGuard version older than 10.10:

Halt the cluster
# cmhaltcl

Re-apply the cluster and package configuration files WITHOUT listing the
package configuration file that will not be included in the new cluster.

# cmapplyconf -C -P ...

3) Release the resources used in the package for other uses:
- strings /etc/lvmtab > lvmtab.out
- vgexport the package volume groups on each server that could
activate them.
- On one server, pvcreate the disks that were in the Volume
Group(s) - to make them available to other VGs. See lvmtab.out
- rmdir mount points for file systems on each adoptive server.
- remove reference to relocatable IP/alias from hostname service files.
- remove the package directory from every server designated to operate it.

Sample process (version 10.10 and later):

# cmviewcl

CLUSTER STATUS
eon_ion up

NODE STATUS STATE
eon up running

PACKAGE STATUS STATE AUTO_RUN NODE
aclk up running enabled eon

NODE STATUS STATE
ion down halted

UNOWNED_PACKAGES

PACKAGE STATUS STATE AUTO_RUN NODE
remove.me down halted enabled unowned

# cmdeleteconf -f -p remove.me
Completed the package deletion.

# cmviewcl

CLUSTER STATUS
eon_ion up

NODE STATUS STATE
eon up running

PACKAGE STATUS STATE AUTO_RUN NODE
aclk up running enabled eon

NODE STATUS STATE
ion down halted
