Configuring Packages and Their Services
Choosing Package Modules
Chapter 6 305
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.
Legal value is any number greater than zero. The default is 1.
If the package needs to mount and unmount 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).
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” on page 377.
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” on page 377.
Legal value is any greater number greater than zero. The default is 1.
Operates in the same way as fs_mount_retry_count (see page 305).
