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

Installs & configures zfs on Ubuntu.


Ubuntu 12.04+



Just include zfs_linux in your node's run_list:

  "run_list": [


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).


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.


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




  • :create: Creates a snapshot of the dataset
  • :prune: Deletes a datasets snapshots down to a specified number of snapshots
  • :purge: Deletes all snapshots for a dataset

Attribute Parameters

  • dataset: Name of the zpool/fileset. Defaults to the resource name.
  • prefix: String to prefix the snapshot name. Defaults to zfs-chef-snap. When pruning/purging snapshots, used to filter the list of snapshots to be deleted (set to nil to disable the search filter).
  • snaps_to_retain: The number of snapshots to retain (only applies to the :prune action). Defaults to 31
  • append_timestamp: Boolean to determine whether a timestamp (in the form of -YY-MM-DD-HHmm) is appended to the snapshot prefix. Defaults to true


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

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

# 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
