Meu problema com o ZFS no Ubuntu Xenial (16.04)
Há anos que executo o ZFS no site zfsonlinux.org do mantenedor do pacote. As coisas têm sido boas. Mas recentemente atualizei para o Ubuntu 16.04 quando foi lançado. Fiquei empolgado por ter o ZFS integrado. E até agora tudo está funcionando muito bem, exceto uma coisa.
zfs share -a
e zfs share filesystem
não funcionam e por conta disso, sempre que reinicio o sistema, zfs-share.service
não habilita meus compartilhamentos SMB configurados no ZFS. Não tive esse problema com o Debian 8.x ou versões anteriores do Ubuntu com os pacotes do zfsonlinux.org.
Enviei isso como um bug com ZoL e Ubuntu. Eu não tenho ideia de quão longe isso irá. Não sei se é um bug ou um problema com o Ubuntu ou comigo. Portanto, também espero que alguém aqui tenha uma ideia ou possa confirmar isso como um problema que está tendo.
ZoL: https://github.com/zfsonlinux/zfs/issues/4999
Ubuntu: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1615405
Veja na parte inferior a minha pergunta real.
Informações de depuração
Sem compartilhamentos! Também verifiquei em vários computadores clientes - foi assim que o problema foi descoberto.

Os conjuntos de dados estão configurados corretamente
root@igor:~# zfs get sharesmb pool2/Media
NAME PROPERTY VALUE SOURCE
pool2/Media sharesmb on local
root@igor:~# zfs get sharesmb pool2/home
NAME PROPERTY VALUE SOURCE
pool2/home sharesmb on local
Mesmo quando eu compartilho manualmente nada acontece
root@igor:~# zfs share -a
root@igor:~# net usershare list
root@igor:~# ls /var/lib/samba/usershares/
root@igor:~#
Mensagem já compartilhada quando compartilho um sistema de arquivos específico
root@igor:~# zfs share pool2/home
cannot share 'pool2/home': filesystem already shared
O código ZFS usa /etc/dfs/sharetab, mas o Linux/Samba não (após a inicialização) https://github.com/zfsonlinux/zfs/issues/190
root@igor:~# cat /etc/dfs/sharetab
/pool2/home - smb on
/pool2/Media - smb on
strace -y zfs share -a Parece que o ZFS não está tentando compartilhar os conjuntos de dados porque os encontra em /etc/dfs/sharetab, mas posso estar interpretando mal isso.

A única maneira de obter os conjuntos de dados compartilhados é redefinir a sharesmb
propriedade paraon
root@igor:~# zfs set sharesmb=on pool2/home
root@igor:~# net usershare list
pool2_home
root@igor:~# zfs set sharesmb=on pool2/Media
root@igor:~# net usershare list
pool2_home
pool2_Media
Minha pergunta
Eu sei que posso corrigir isso adicionando essas entradas em /etc/rc.local
zfs set sharesmb=on pool2/Main
zfs set sharesmb=on pool2/home
E eu vou. Mas alguém sabe por zfs share -a
que não funciona como pretendido (como sempre funcionou)? Alguém mais experimentou isso? Talvez isso afete todas as instalações do Ubuntu Xenial ou talvez seja só eu. Mesmo que não haja correção e seja um bug, gostaria de saber.
Obrigado!
