Control: forwarded -1 https://github.com/openzfs/zfs/issues/12430 Control: tags -1 + upstream
Hi Andreas, aron and I did some investigation. The -1 reported by zfs_umount is actually -EPERM. This has been discussed by upstream issue #12430. You may want to try (as workaround): 1. skip pam_zfs_key when pam_systemd is used, as #12430 suggests; or, 2. use `zfs allow` to grant `mount` permission to yourself. Thanks, Shengqi Chen
