rdist usage

RHA — Fri, 22 Jul 2005 04:55:50 GMT

Hi All,

I am migrating data (5 filesystems) on a HPUX 11 server, the source and target areas are NFS mounted on the HP box, from different resources.

I was planning to use rdist to do the initial copy and subsequent incrementals.

I wanted to know if it is possible, just using a command, rather than creating a rdist config file. I have included below my planned script to initiate the copy. Please advise me if this is correct.

rdist -hMRw
rdist -hMRw
rdist -hMRw
etc
etc

Any help would be appreciated.

Thanks

Hi,

have a look at this page:
http://docs.hp.com/en/B3921-90010/rdist.1.html
I think you can do it with the -c option.

greetings,

Michael

RHA,
I do not see any problem since the source and target are both on the same server after the nfs mount.

However since rdis is for remote distribution, I have always used a distfile and that makes life much easier

If you follow the example in th man page you will easily be able to accomplish what you want.

thanks

I use(d) rdist for my home directory and apparently it definitely *needs* a config file.

If You want a - in my experience - much better too for this job, look at rsync!

(but even cd inpath ; find -depth | cpio -pdm /outpath/ should work better)

You need a config..

Here's mine for a SAP id on a MC/SG cluster:

First, the cron entry:

# Copy prdadm across to the DR site.
05 01 * * * /app/admin/drp/update-binaries.sh

# cat /app/admin/drp/update-binaries.sh
#! /bin/sh

# Keep the DRP copy of the vgpadm up-to-date.
# Currently the files are in:
#
# /home/prdadm/DR
#
# See the rdist(1M) distfile for a list of exclusions.

DRPDIR=/app/admin/drp
DRPHOST=svr031

HOST=`/usr/bin/uname -n`
PRD=`cmviewcl |grep prddbci |awk '{print $5}'`
if [ "$HOST" = "$PRD" ]
then
mount | grep /home > /dev/null 2>&1
if [ $? -eq 0 ]
then
for vg in `ls -d /dev/vg5* |awk -F/ '{print $3}'`
do
/usr/sbin/vgexport -p -s -v -m /home/prdadm/DR/$vg.map /dev/$vg
done
cp -p /etc/cmcluster/PRDDBCI/prddbci.cntl /home/prdadm/DR/
cp -p /etc/cmcluster/PRDDBCI/prddbci.cntl.full /home/prdadm/DR/
cp -p /etc/cmcluster/PRDDBCI/prddbci.cntl.mountonly /home/prdadm/DR/
( su - prdadm -c "rdist -f $DRPDIR/distfile prdadm"; ) 2>&1 |\
tee $DRPDIR/drp.log 2>&1 |\
mailx -s "prdadm DRP rdist output" `cat /usr/local/mailadmin.list`
fi
fi

# cat /app/admin/drp/distfile
PRDDR = ( svr031 )

#
# File systems to be copied over to the DR host.
# Don't use -R in install - so as not to remove files on destination host
PRDADM = /home/prdadm

prdadm: ( ${PRDADM} ) -> ( ${PRDDR} )
install -w ;

Rgds...Geoff
