GBROWSE...S_SLAVE(1p)

✨ NAME ✨

gbrowse_sync_aws_slave.pl — bestie, this is the little script that syncs your local file system over to your GBrowse slave volume 💖 (it lives in section 1p of the User Contributed Perl Documentation, iykyk)

🌸 SYNOPSIS 🌸

% sudo gbrowse_sync_aws_slave.pl --conf     /etc/gbrowse2/aws_balancer.conf \
                                 --mysql    /var/lib/mysql \
                                 --postgres /var/lib/postgresql

syncing data....done
data stored in snapshot(s) snap-12345
updated conf file, previous version in /etc/gbrowse2/aws_balancer.conf.bak

like... it literally prints that back at you when it's done, so satisfying fr fr ✨

🦋 DESCRIPTION 🦋

okay so. This script runs in conjunction with Amazon Web Server-based GBrowse render slave load balancing — the whole thing is described way more in the manual page for gbrowse_aws_balancer.pl, so go read that if you want the full lore.

The gbrowse_sync_aws_script.pl script should be run on the GBrowse master machine every single time you add a new database to an existing data source, or if you add a whole new data source. no skips. What it does is prepare a new Amazon EBS snapshot containing a copy of all the data the GBrowse slave needs to run. That snapshot then gets attached to new slave instances. main character energy honestly 👑

After running, it updates the conf file with the current versions of the slave AMI and the data snapshot(s).

% sudo gbrowse_sync_aws_script.pl --conf     /etc/gbrowse2/aws_balancer.conf \
                                  --mysql    /var/lib/mysql \
                                  --postgres /var/lib/postgresql

The --conf argument is required — no --conf, no party 🙈 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've created mysql or postgres databases, you must also give the paths to their database file directories, as shown in the example above.

⚠️ heads up bestie!! Note that ALL your mysql and postgres data files located on the master machine will be copied — not just those used for track display. like, all of them. every last one. 💀
