Hi *,
The following script uses rsync over LAN to mirror a

raid1 array. If anyone has a better method for

performing the task, I'd be interested in knowing

about it or my method is OK but the script could use

some improvements, etc. Please don't be sensetive with

your comments. I really like having my ass handed to

me.
The problem with rsync mirror occurs when the source

is lost and rsync mirrors nothing. The mirror is

supposed to be a backup. I'll read the rsync man page

but maybe someone knows an appropriate solution.
#!/bin/bash

#rsync; mirror studioagig:~/clients/$remLABEL (remote

removable media) /media/clients/$locLABEL (local) if

device LABELs match

#write labels with /sbin/tune2fs -L fsb /dev/sda1

#root priveleges are required to run dumpe2fs
#find label for remote scsi device

for arg in `ssh root@studioagig ls /dev/sd[b-d][1-16]`

do

   echo `ssh root@studioagig /sbin/dumpe2fs -h $arg

|grep Filesystem\ volume\ name` >

~/.bin/RemoteSyncInclude

done
#find label for local mirror device

for arg in `ls /dev/sd[a-f][1-16]`

do

   echo `/sbin/dumpe2fs -h $arg |grep Filesystem\

volume\ name` > ~/.bin/LocalSyncInclude

done
remLABEL=`cat ~/.bin/RemoteSyncExclude |sed

's/Filesystem volume name:\ //'`

locLABEL=`cat ~/.bin/LocalSyncExclude |sed

's/Filesystem volume name:\ //'`
if [ "$remLABEL" == "$locLABEL" ]; then

    rsync --rsh=ssh --times --perms --owner --compress

--delete --recursive --partial --temp-dir=/tmp

--bwlimit=0

studio@studioagig:/home/studio/clients/$remLABEL/

/media/clients

fi

exit
Thanks,
Ron
