vxfs_ifree_timelag(5) vxfs_ifree_timelag(5)

(Tunable Kernel Parameters)

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.

Minimum

None

Maximum

None

Default

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 parame-

ter 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 HP-UX Release Notes at
