.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This script is run in conjunction with Amazon Web Server-based GBrowse
render slave load balancing, which is described in more detail in the
manual page for gbrowse_aws_balancer.pl.
.PP
The gbrowse_sync_aws_script.pl script should be run on the GBrowse
master machine each time you add a new database to an existing data
source, or if you add a whole new data source. What it does is to
prepare a new Amazon \s-1EBS\s0 snapshot containing a copy of all the data
needed for the GBrowse slave to run. This snapshot is then attached to
new slave instances.
.PP
After running, it updates the conf file with the current versions of
the slave \s-1AMI\s0 and the data snapshot(s).
.PP
.Vb 3
\& % sudo gbrowse_sync_aws_script.pl \-\-conf     /etc/gbrowse2/aws_balancer.conf \e
\&                                   \-\-mysql    /var/lib/mysql \e
\&                                   \-\-postgres /var/lib/postgresql
.Ve
.PP
The \-\-conf argument is required. The script will create a snapshot of
the appropriate size, mount it on a temporary staging instance, and
rsync a copy of your gbrowse databases directory
(e.g. /var/lib/gbrowse2/databases) to the snapshot. If you have
created mysql or postgres databases, you must also give the paths to
their database file directories, as shown in the example.
.PP
Note that \s-1ALL\s0 your mysql and postgres data files located on the master
machine will be copied; not just those used for track display.
