Online reconfiguration of modular CFS package parameters
You can reconfigure existing modular CFS packages online, i.e., even when the package is running.
Online reconfiguration of modular CFS packages involves addition, removal, and/or modification
of CVM/CFS parameters for disk group, mount point, checkpoint, and snapshot packages. For
steps on how to reconfigure a package, see “Reconfiguring a Package” (page 310).
The following table lists the parameters that can be reconfigured online for the various modular
CFS packages:

cvm_activation_modecvm_disk_groupcvm_disk_groupDisk group
NOTE: Modifying this parameter
typically works as an offline
operation. When you modify
cvm_activation_mode, the
changes are reflected only when
the package is restarted on a
given node or when a new node
is added. This is due to the
limitation that changing CVM
parameters while they are in use
is not supported by Symantec.
If a mount point is associated with
a disk group, when you modify
cvm_activation_mode, the
cfs_mount_options may be
incompatible with the new disk
group. In such a case, the
package could fail on restart. You
must manually validate that this
change is compatible with the
mount points.
