Upgrade ZFS from 0.8 to 2.3.0 version

I’m going to upgrade an old server from ZFS 0.8 to version 2.3.0 and want to clarify a few key points before proceeding.

If anyone has experience upgrading from 0.8 to 2.3.0, I’d greatly appreciate your insights.

  1. Are there any particular steps in the upgrade process, both before and after, besides running zpool upgrade?
  2. Is it necessary to stop any load (read/write operations) on the filesystem during the upgrade?
  3. Have there been any failures when upgrading ZFS to version 2.3.0 (data loss or corruption)?

ZFS isn’t included in Fedora.

Whatever you do, have at least 2 backups before upgrading if the files are important to you

What version of Fedora are you running on? How did you install zfs capabilities?

Are you referring to zfs on root or a zfs data pool mounted on your Fedora server?
