Hi.
I'm planning an networker ugrade from 7.4.4 to 7.5.1 in our distributed
environment consisting of 5 storage nodes and some 500 clients. We're using
single data zone.
Acoring to documentation this is pretty easy.
it's recomended to run these commands
nsrim –X
nsrck –m
nsrck –L6
With 500 clients, this nsrck can take more than a day. This is a
quote from a letter I sent to this forum on November 18th, 2008:
" If you need to run to run nsrck -L6, I suggest that you will do that
in parallel. I use the following script (on Solaris) to get things to
run faster:
#!/bin/sh
cd /nsr/index
CLIENTS=`du -sk * | sort -nr | awk '{print $2}'`
for client in $CLIENTS
do
echo $client
at -s -qd now<<EOB
time nsrck -L6 $client
EOB
sleep 1
done
You need to add the third line to queuedefs for the above to work. It
runs 20 jobs (on a 24 threads T1000). Since this process is CPU bound
there is no point in doing much more than your processors (say five for
your typical quad core Intel CPU).
# cat /etc/cron.d/queuedefs
a.4j1n
b.10j2n90w
d.20j4n60w
With the above I was able to check 70Gb of index which took over 22
hours in under four hours."
upgrade the storage nodes first. After that,it's pretty much next-next-
finish.
Is anyone out there with experience doing an 7.5.1 upgrade? any issues? and
how where the issues resolved?
Last time I spoke with GlassHouse, they said that this upgrade is not
recommended and that I should stay at 7.4.4. I am, however, dissatisfied
with 7.4.4 which I why I wanted to upgrade. If you want to upgrade
because of stability, I think 7.4.4.4 might be a better option (if you
can get it). I will give a call to GH and see if I can get it from them.
