Configuring Packages and Their Services
Choosing Package Modules
Chapter 6294
This allows package startup to continue while mirror re-synchronization
is in progress.
vg Specifies an LVM volume group (one per vg, each on a new line) on
which a file system needs to be mounted. A corresponding
vgchange_cmd (see page 292) specifies how the volume group is to be
activated. The package script generates the necessary filesystem
commands on the basis of the fs_ parameters (see page 295).
cvm_dg Specifies a CVM disk group (one per cvm_dg, each on a new line)
used by this package. CVM disk groups must be specified whether file
systems need to be mounted on them or not. A corresponding
cvm_activation_cmd (see page 293) specifies how the disk group is to
be activated.
vxvm_dg Specifies a VxVM disk group (one per vxvm_dg, each on a new
line) on which a file system needs to be mounted. See the comments in
the package configuration file, and “Creating the Storage Infrastructure
and Filesystems with LVM and VxVM” on page 221, for more
information.
deactivation_retry_count Specifies how many times the package
shutdown script will repeat an attempt to deactivate a volume group
(LVM) or disk group (VxVM, CVM) before failing.
Legal value is zero or any greater number. Default is zero.
kill_processes_accessing_raw_devices Specifies whether or not to
kill processes that are using raw devices (for example, database
applications) when the package shuts down. Default is no. See the
comments in the package configuration file for more information.
concurrent_fsck_operations The number of concurrent fsck
operations allowed on file systems being mounted during package
startup.
Legal value is any number greater than zero. The default is 1.
If the package needs to run fsck on a large number of filesystems, you
can improve performance by carefully tuning this parameter during
testing (increase it a little at time and monitor performance each time).
concurrent_mount_and_umount_operations The number of
concurrent mounts and umounts to allow during package startup or
shutdown.
