[lustre-discuss] "zpool upgrade -a" command for upgrade from lustre-2.12 to lustre 2.15 needed?

[Bernd Melchers]

Hi All,
for the process of update from CentOS-7 / lustre-2.12.9 / zfs-0.7 to
Alma-8 / lustre-2.15 / zfs-2.1 we would like to know if the zfs pools
have to be upgraded (with "zpool upgrade -a"). This will make newer zfs
features available to lustre, but with the disadvantage that there is no
way back to zfs-0.7 and lustre-2.12. Which zfs level does lustre-2.15
need?

Mit freundlichen Grüßen
Bernd Melchers
