NAME
vxfs_ifree_timelag — VxFS inode free time lag (specifies the minimum time to be spent on a freelist)
SYNOPSIS
/usr/bin/kctune -s vxfs_ifree_timelag={value}
VALUE
Specify an integer value.
DESCRIPTION
In VxFS, the unused inodes are put on a freelist. The memory space for this
unused inode is freed if it stays on the freelist for a specified amount of
time. The
vxfs_ifree_timelag
tunable specifies the minimum amount of time should spend on a freelist
before its memory space is freed. The time is specified in seconds.
vxfs_ifree_timelag
is a dynamic tunable. Any changes to
vxfs_ifree_timelag
take effect immediately.
EXAMPLES
Change the value of
vxfs_ifree_timelag
to 2400 seconds:
# kctune -s vxfs_ifree_timelag=2400
WARNING
Incorrect tuning of
vxfs_ifree_timelag
may adversely affect system performance.
All HP-UX kernel tunable parameters are release specific.
This parameter may be removed or its meaning may change in
the future releases of HP-UX.
Installation of optional kernel software, from HP or other vendors,
may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or
recommended values. For information about the effects of
installation on tunable values, consult the documentation
for the kernel software being installed.
For information about optional kernel software that was
factory installed on your system, see
