Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

zfs_linux Cookbook

Gitter

Installs & configures zfs on Ubuntu.

Requirements

Ubuntu 12.04+

Usage

zfs_linux::default

Just include zfs_linux in your node's run_list:

{
  "name":"my_node",
  "run_list": [
    "recipe[zfs_linux]"
  ]
}

zfs_linux::auto-snapshot

Installs the zfs-auto-snapshot package, which automatically sets up rotating snapshots (hourly snapshots kept for a day, daily snapshots kept for a month, etc).

zfs_linux::auto-scrub

Uses cron.d (via the cron cookbook) to setup cron jobs on Sunday morning for each zpool. If greater than 4 zpools are present, runs the checks once a month on the first Sunday.

zfs_linux::source

This recipe was developed to allow the deployment of ZoL from a specific commit. Apply it to your node to pull down the ZFS revision from git (specified in your node's attributes).

WARNING: On Debian-family systems, the current build method will disable automatic updates for your kernel because the ZoL packages will be built for the kernel that is running at the time of compilation. Do not apply this without a process in place for monitoring security updates and applying them manually in the following manner: 1. Update your system kernel packages 2. Disable the auto-start of any services that depend on your ZoL-mounted volumes 3. Reboot into the new kernel 4. Delete the zfs & spl directories in /var/chef/cache/ 5. Perform a chef-client run 6. Enable auto-start again for your node's services 7. Reboot

Examples

# Create a snapshot with a specific name
zfs_linux_snapshot 'tank/mydataset' do
  prefix 'myweeklysnapshot'
  append_timestamp false
end

# Delete all snapshots that match 'weekly'
zfs_linux_snapshot 'tank/mydataset' do
  prefix 'weekly'
  action :purge
end

# Remove all but the last 6 monthly snapshots
zfs_linux_snapshot 'tank/mydataset' do
  prefix 'zfs-auto-snap_monthly'
  snaps_to_retain 6
  action :prune
end
