Backups

backup.osgeo.org (aka osgeo5, mirror)

This was the OSUOSL VM used for backups starting in 2010/04 and is now upgraded to dedicated hardware (very) early in 2014. It is used for Bacula backups of OSU OSL VMs and Rsync backups of the public space at "download.osgeo.org".

Admins: Frank Warmerdam (rsync), Martin Spott (bacula), Sandro Santilli (bacula)
access is via SAC shell group.
download.osgeo.org rsync mirroring runs nightly and is externally available at download2.osgeo.org.
/backup/bacula/ contains the Bacula storage device
/backup/rsync/ is for rsync backups
/backup/longterm/ is for long term backups of static material (ie conference web sites)
/backup/pgdump/ contains PostgreSQL dumps of the Bacula director database
/etc/bacula contains Bacula configuration, is under local git repo

Hardware

CPU: Intel Xeon E3-1220v2, 3.1GHz (4-Core, 8MB Cache, 69W) 22nm

Controller: 2 Ports 6Gb/s SATA, and 4 Ports 3Gb/s SATA via Intel C216 Chipset
PCIe 3.0 x16: No Item Selected
PCIe 2.0 x4 (x8): No Item Selected
NOTE: Drives will be connected to onboard SATA controller unless otherwise specified
Hot-Swap Drive - 1: 3TB Seagate Constellation ES.3 (6Gb/s, 7.2K RPM, 128MB Cache) 3.5-inch SATA
Hot-Swap Drive - 2: 3TB Seagate Constellation ES.3 (6Gb/s, 7.2K RPM, 128MB Cache) 3.5-inch SATA
Hot-Swap Drive - 3: 3TB Seagate Constellation ES.3 (6Gb/s, 7.2K RPM, 128MB Cache) 3.5-inch SATA
Hot-Swap Drive - 4: 3TB Seagate Constellation ES.3 (6Gb/s, 7.2K RPM, 128MB Cache) 3.5-inch SATA
Optical Drive: Blanking Panel, No Optical Drive
Front Input: Blanking Panel - No Front Inputs
Power Supply: Redundant 500W Power Supply with PMBus - 80 PLUS Platinum Certified
Rail Kit: 1U Sliding Rail Kit
OS: No Item Selected
Warranty: Standard 3-Year Warranty
Notes:
New quote with redundant power supply. Can I get a 2.5 inch spinning
disk instead of SSD in the Front Input slot (500 GB Seagate
Constellation 6 GB/s 2.5")?

OS installation

Create an empty partition at the beginning of every hard drive, use "Reserved BIOS boot area" on GPT-partitioned disks (typical with 2 GByte disks or bigger) or just "Unused" on DOS-type partition tables. By tradition I reserve 10 MByte on each disk, maybe 1 MByte would be sufficient as well, but these 9 MByte of difference don't cost that much and you're on the safe side ....
Create a second partition on every disk - for use by MD - allocating all the remaining disk space
MD RAID5 over all the 'second' partitions for use by LVM - 8 TB usable space
LVM volume group on top of the MD physical volume
Volumes
- "boot" (256 MByte, Ext2, /boot/),
- "root" (20 GByte, XFS, /root/),
- "swap" (8 GByte),
- "var" (20 GByte, XFS, /var/)
Install the base operating system, don't forget to set up SSH ;-)
Volumes
- "backup" (2 TByte, XFS, /backup/),
- "mirror" (1 TByte, XFS, /mirror/)

osgeo3 & osgeo4

See: Infrastructure Transition Plan 2010

download.osgeo.org

As noted in Download Server the contents of download.osgeo.org are rsync'ed to osgeo2.

ProjectsVM

Bacula - we need details.

??? How does it work?

svn.osgeo.org

As noted in Subversion the subversion repository is mirrored using svn mirroring and does not need to be backed up otherwise.
