I'm using 3 Redhat6.0 boxes, which have been running happily for a couple of years. One box is an NIS server, and all three machines cross-mount drives via NFS using an automounter. However, in the last couple of days the automount performance has degraded. Sometimes automounting is very slow (10 to 20 seconds), and occasionally it times out and fails. Once automounting has taken place disk performance is normal.
The /etc/auto.master file from one of the machines is:
# $Id: auto.master,v 1.2 1997/10/06 21:52:03 hpa Exp $
# Sample auto.master file
# Format of this file:
# mountpoint map options
# For details of the format look at autofs(8).
#/misc /etc/auto.misc --timeout 60
/import /etc/auto.misc --timeout 60
and the /etc/auto.misc file is:
$Id: auto.misc,v 1.2 1997/10/06 21:52:04 hpa Exp $
auton_data -rw,rsize=8192,wsize=8192 auton:/auton_data
auton_user -rw,rsize=8192,wsize=8192 auton:/auton_user
lydat_data -rw,rsize=8192,wsize=8192 lydat:/lydat_data
lydat_user -rw,rsize=8192,wsize=8192 lydat:/lydat_user
Neither of these files have been altered in the last few days. ping is not detecting any network problems or lost packets. Any clues??
