Oh, same as over here. Perhaps we need to hear more about the history of your host.

"Oh joy. The #OpenZFS <https://soc.feditime.com/tag/openzfs> version in EL 9.x is really old. The pool was part of an 11.1 #FreeBSD <https://soc.feditime.com/tag/freebsd> release and had the com.klarasystems:vdev_zaps_v2 feature which isn't included. It is only a backup pool anyway so time to nuke and pave. #ZFS <https://soc.feditime.com/tag/zfs>"
