  * Enabling cronjob snapshots:

examples:

  enable-snapshot -m 10 -H 4 -D "*" -M "*" -d "*" -N data/hosts/wheezy -t filesystem -k 7

Take a snaphot of filesystem data/hosts/wheezy every day at 4:10 am, keep 7 snapshots (here's days).

  enable-snapshot -m 21 -H 4 -D "*" -M "*" -d "*" -N data/hosts/gluster1 -t volume -k 30

Take a snaphot of volume data/hosts/gluster1 every day at 4:21 am, keep 30 snapshots (here's days).

  * Enabling cronjob replicas

examples:

  enable-replica -o data/hosts/comp -r baie3/data/hosts/comp -n 7 -s r720data4 -m 0 -H 5 -D "*" -M "*" -d "*"

Copy data from data/hosts/comp to baie3/data/hosts/comp, on r720data4 server, every day at 5:00 am, keep 7 snapshots

  * Mandatory

zfs on linux (see http://zfsonlinux.org/ )

smartctl (smartmontools)

mbuffer (mbuffer)

  * install GUI on "manager"

apt-get	install openjdk-7-jre openjdk-7-jre-headless

optional: apt-get install smartmontools mbuffer xbase-clients

create /opt/gZFS/

rsync from svn (rsync --exclude '.svn*') bin/ and jarjarbin/ to /opt/gZFS/

example: 

rsync --recursive --exclude '.svn*' -e ssh ~/home/project/gZFS/bin root@<manager>:/opt/gZFS/

rsync --recursive --exclude '.svn*' -e ssh ~/home/project/gZFS/jarjarbin root@<manager>:/opt/gZFS/

launch the GUI (user root):

java -jar /opt/gZFS/jarjarbin/gZFS-linux-x64.jar

See the GUI manual.

if manager also host zfs datasets that will be managed, see managed servers doc.

  * install tools on each "managed" servers :

apt-get install smartmontools mbuffer

rsync from "manager" :

example: rsync --recursive --exclude "infodisks.cache" --exclude "jarjarbin" -e ssh root@<manager>/opt/gZFS /opt/

create /opt/gZFS/replicas/ and /opt/gZFS/snapshots/

make symbolic links to scripts :

for i in $(ls /opt/gZFS/bin/); do ln -s /opt/gZFS/bin/$i /sbin/$i ; done

create cache :

get-disk-zpool > /opt/gZFS/infodisks.cache
