yumリポジトリ設定が異常で更新できなかっただけで、
正常化した所普通に更新できました。

[root@xfs ~]# zpool upgrade
This system supports ZFS pool feature flags.

All pools are formatted using feature flags.


Some supported features are not enabled on the following pools. Once a
feature is enabled the pool may become incompatible with software
that does not support the feature. See zpool-features(5) for details.

POOL  FEATURE
---------------
tank
      redaction_bookmarks
      redacted_datasets
      bookmark_written
      log_spacemap
      livelist
      device_rebuild
      zstd_compress

新機能は詳しく見てないですが、互換性を見る限り使うべきか不安になる感じです。
まあ、次はUbuntuかなと思っており、UbuntuもOpenZFSなので大丈夫そうな気はしますが。

でせっかくバージョン変わったので、
HDDの入れ替え時のパフォーマンスの測定とかしたいけど、
アップデートの直前に全台のHDDの入れ替えが終わったとこなので今からは流石に無理。。
1台あたり47時間くらいかかったので。
