A logical volume can be created in an LVM volume group, a Veritas VxVM disk group, or a Veritas
CVM disk group. Logical volumes can be entered in any order, regardless of the type of storage
group. The parameter explanations that follow provide more detail.
For an NFS-imported file system, see the discussion under fs_name (page 238) and fs_server
(page 238).
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 file systems, 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.
Legal value is any number greater than zero. The default is 1.
If the package needs to mount and unmount a large number of file systems, you can improve
performance by carefully tuning this parameter during testing (increase it a little at time and monitor
performance each time).
fs_mount_retry_count
The number of mount retries for each file system. Legal value is zero or any greater number. The
default is zero.
If the mount point is busy at package startup and fs_mount_retry_count is set to zero, package
startup will fail.
If the mount point is busy and fs_mount_retry_count is greater than zero, the startup script
will attempt to kill the user process responsible for the busy mount point (fuser -ku) and then
try to mount the file system again. It will do this the number of times specified by
fs_mount_retry_count.
If the mount still fails after the number of attempts specified by fs_mount_retry_count, package
startup will fail.
This parameter is in the package control script for legacy packages. See “Configuring a Legacy
Package” (page 289).
fs_umount_retry_count
The number of umount retries for each file system. Replaces FS_UMOUNT_COUNT, which is still
supported in the package control script for legacy packages; see “Configuring a Legacy Package”
(page 289).
Legal value is any greater number greater than zero. The default is 1. Operates in the same way
as fs_mount_retry_count (page 237).
