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 mean-

ing may change in the future releases of HP-UX.
