I want to add monitoring nfs file systems back into the 4.2 sunos client, but don't want the whole client to hang if nfs hangs. I changed the scripting to the df test to kill the hanging df and display "&red - df $1 check failed" message, if the df does not complete in 3 seconds. That part seems to work OK. The only thing I think I need is get the hobbit server to change the "disk" status to red or yellow.
- What do I need to change to get "disk status" to change color?
- Is there any down side to what I am trying to do?
I changed df test in hobbitclient-sunos.sh to the following:
echo "[df]"
Get df header
FSTYPESH=/bin/df -n -l|awk '{print $3}'|egrep -v "^proc|^fd|^mntfs|^ctfs|^devfs|^objfs|^nfs"|sort|uniq
set $FSTYPESH
/bin/df -F $1 -k | head -1
All of this because Solaris df cannot show multiple fs-types, or
exclude certain fs types.
#FSTYPES=/bin/df -n -l|awk '{print $3}'|egrep -v "^proc|^fd|^mntfs|^ctfs|^devfs|^objfs|^nfs"|sort|uniq
FSTYPES=/bin/df -n|awk '{print $3}'|egrep -v "^proc|^fd|^mntfs|^ctfs|^devfs|^objfs"|sort|uniq
if test "$FSTYPES" = ""; then FSTYPES="ufs"; fi
set $FSTYPES
while test "$1" != ""; do
( /bin/df -F $1 -k | grep -v " /var/run" | tail +2 ) & cmdpid=$!
timeout=3
(sleep $timeout; echo "&red - df $1 check failed" ; kill -9 $cmdpid
/dev/null 2>&1) & watchdogpid=$! wait $cmdpid # wait for command kill $watchdogpid >/dev/null 2>&1 shift done
During a df hang the web page source shows the following:
Filesystem kbytes used avail capacity Mounted on <IMG SRC="/hobbit/gifs/red.gif" ALT="red" HEIGHT="16" WIDTH="16" BORDER=0> - df nfs check failed /dev/dsk/c0t0d0s0 2052750 1407222 583946 71% / /dev/dsk/c0t0d0s3 2052750 184667 1806501 10% /var /dev/dsk/c0t1d0s0 5038454 3349374 1638696 68% /opt2 /dev/dsk/c0t0d0s4 2052750 1757484 233684 89% /opt /dev/dsk/c0t0d0s5 1015542 724217 230393 76% /tmp
The Client data df section shows the following raw data: [df] Filesystem kbytes used avail capacity Mounted on &red - df nfs check failed /dev/dsk/c0t0d0s0 2052750 1407222 583946 71% / /dev/dsk/c0t0d0s3 2052750 184667 1806501 10% /var /dev/dsk/c0t1d0s0 5038454 3349374 1638696 68% /opt2 /dev/dsk/c0t0d0s4 2052750 1757484 233684 89% /opt /dev/dsk/c0t0d0s5 1015542 724217 230393 76% /tmp
