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 linux. Currently primarily targeting 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::snapshot-pruning

Complements the auto-snapshot recipe by providing a mechanism (via attributes) for controlling how many snapshots are retained on a daily basis. Action is only taken if attributes like the following are set:

"zfs": {
  "filesystems": [
    {
      "zfsfilesytem1": {
        "zpool": "zpool1",
        "snapshot_retention": {
          "monthly": "3",
          "weekly": "2",
          "daily": "15"
        }
      }
    },
    ...
  ]
}

The retention values (each are optional) dicate the number of the most recent snapshots to keep. So in the example above, each day the snapshots of zpool1/zfsfilesystem1 will be evaluated and only the 15 most recent daily snapshots will be kept, etc. For any given snapshot type you can set the value to "0" to have all snapshots of that type deleted.

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
