Andriy Gapon bdc44f62ff 7431 ZFS Channel Programs ... illumos/illumos-gate@dfc115332c dfc115332c https://www.illumos.org/issues/7431 ZFS channel programs (ZCP) adds support for performing compound ZFS administrative actions via Lua scripts in a sandboxed environment (with time and memory limits). This initial commit includes both base support for running ZCP scripts, and a small initial library of API calls which support getting properties and listing, destroying, and promoting datasets. Testing: in addition to the included unit tests, channel programs have been in use at Delphix for several months for batch destroying filesystems. The dsl_destroy_snaps_nvl() call has also been replaced with For reference, the new zfs-program manpage is included below. ZFS-PROGRAM(1M) 1M ZFS-PROGRAM(1M) NAME zfs program – executes ZFS channel programs SYNOPSIS zfs program [-t timeout] [-m memory-limit] pool script DESCRIPTION The ZFS channel program interface allows ZFS administrative operations to be run programmatically as a Lua script. The entire script is executed atomically, with no other administrative operations taking effect concurrently. A library of ZFS calls is made available to channel program scripts. Channel programs may only be run with root privileges. A modified version of the Lua 5.2 interpreter is used to run channel program scripts.
