state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not support
the features. See zpool-features(5) for details.

zpool upgrade
Re: zpool upgrade
root@pveh:~# 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.
embedded_data
Blocks which compress very well use even less space.
bookmarks (read-only compatible)
"zfs bookmark" command
filesystem_limits (read-only compatible)
Filesystem and snapshot limits.
large_blocks
Support for blocks larger than 128KB.
large_dnode
Variable on-disk size of dnodes.
sha512
SHA-512/256 hash algorithm.
skein
Skein hash algorithm.
edonr
Edon-R hash algorithm.
userobj_accounting (read-only compatible)
User/Group object accounting.
encryption
Support for dataset level encryption
project_quota (read-only compatible)
space/object accounting based on project ID.
device_removal
Top-level vdevs can be removed, reducing logical pool size.
obsolete_counts (read-only compatible)
Reduce memory used by removed devices when their blocks are freed or remapped.
zpool_checkpoint (read-only compatible)
Pool state can be checkpointed, allowing rewind later.
spacemap_v2 (read-only compatible)
Space maps representing large segments are more efficient.
allocation_classes (read-only compatible)
Support for separate allocation classes.
resilver_defer (read-only compatible)
Support for deferring new resilvers when one is already running.
bookmark_v2
Support for larger bookmarks
The following legacy versions are also supported:
VER DESCRIPTION
--- --------------------------------------------------------
1 Initial ZFS version
2 Ditto blocks (replicated metadata)
3 Hot spares and double parity RAID-Z
4 zpool history
5 Compression using the gzip algorithm
6 bootfs pool property
7 Separate intent log devices
8 Delegated administration
9 refquota and refreservation properties
10 Cache devices
11 Improved scrub performance
12 Snapshot properties
13 snapused property
14 passthrough-x aclinherit
15 user/group space accounting
16 stmf property support
17 Triple-parity RAID-Z
18 Snapshot user holds
19 Log device removal
20 Compression using zle (zero-length encoding)
21 Deduplication
22 Received properties
23 Slim ZIL
24 System attributes
25 Improved scrub stats
26 Improved snapshot deletion performance
27 Improved snapshot creation performance
28 Multiple vdev replacements
