After being upgraded, these pools will no longer be accessible by software that does not support feature flags. VER POOL --- ------------ 28 tank 28 zfspool Use 'zpool upgrade -v' for a list of available legacy versions. Every feature flags pool has all supported features enabled. root@blackcube:~/bin # zpool upgrade -v This system supports ZFS pool feature flags. The following features are supported: FEAT DESCRIPTION ------------------------------------------------------------- async_destroy (read-only compatible) Destroy filesystems asynchronously. empty_bpobj (read-only compatible) Snapshots use less space. lz4_compress LZ4 compression algorithm support. multi_vdev_crash_dump Crash dumps to multiple vdev pools. spacemap_histogram (read-only compatible) Spacemaps maintain space histograms. enabled_txg (read-only compatible) Record txg at which a feature is enabled hole_birth Retain hole birth txg for more precise zfs send extensible_dataset Enhanced dataset functionality, used by other features. bookmarks (read-only compatible) "zfs bookmark" command filesystem_limits (read-only compatible) Filesystem and snapshot limits.
