file systems will no longer be accessible on systems running older
versions of the software.
zfs
send streams generated from new
snapshots of these file systems cannot be accessed on systems running
older versions of the software.
In general, the file system version is independent of the pool version. See
zpool(8) for information on the
zpool
upgrade command.
In some cases, the file system version and the pool version are interrelated
and the pool version must be upgraded before the file system version can
be upgraded.
-V
version- Upgrade to the specified version. If
the
-V flag is not specified, this
command upgrades to the most recent version. This option can only be
used to increase the version number, and only up to the most recent
version supported by this software.
-a- Upgrade all file systems on all imported pools.
- filesystem
- Upgrade the specified file system.
-r- Upgrade the specified file system and all descendent file
systems.
