O comando “zfs share” do Ubuntu Xenial (16.04) não funciona para compartilhamentos SMB

Meu problema com o ZFS no Ubuntu Xenial (16.04)

Eu venho executando o ZFS há anos no site zfsonlinux.org do mantenedor de pacotes. As coisas foram boas. Mas recentemente eu atualizei para o Ubuntu 16.04 quando ele foi lançado. Fiquei empolgado por ter o ZFS integrado. Até agora, tudo está funcionando bem, exceto uma coisa.

zfs share -a e zfs share filesystem não funcionam e, por isso, sempre que reinicializo o sistema, zfs-share.service não ativa meus compartilhamentos SMB configurados no ZFS. Eu não tive esse problema com o Debian 8.x ou versões mais antigas do Ubuntu com os pacotes do zfsonlinux.org.

Eu enviei isso como um bug com o ZoL e o Ubuntu. Eu não tenho ideia de quão longe isso irá. Eu não sei se é um bug ou um problema com o Ubuntu ou comigo. Então eu também espero que alguém aqui tenha uma ideia ou possa confirmar isso como um problema que eles estão tendo também.

Informações de depuração

Sem compartilhamentos! Eu também verifiquei em vários computadores clientes - foi assim que o problema foi descoberto.

Os conjuntos de dados são 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 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 o / etc / dfs / sharetab, mas o Linux / Samba não (após a inicialização) link 

root@igor:~# cat /etc/dfs/sharetab 
/pool2/home     -       smb     on
/pool2/Media    -       smb     on

strace -y zfs share -a Parece que o ZFS não pode tentar compartilhar os conjuntos de dados porque os encontra em / etc / dfs / sharetab, mas eu poderia estar interpretando mal isso.

A única maneira de obter os conjuntos de dados compartilhados é redefinir a propriedade sharesmb para on

%pre%

Minha pergunta

Eu sei que posso consertar isso adicionando essas entradas em /etc/rc.local

%pre%

E eu vou. Mas alguém sabe por que zfs share -a não funciona como deveria (como sempre)? Alguém mais experimentou isso? Talvez isso afete todas as instalações do Ubuntu Xenial ou talvez seja apenas eu. Mesmo que não haja conserto e seja um bug, eu gostaria de saber.

Obrigado!

Encontrei a minha resposta e, infelizmente, não é bom

Eu recebi uma resposta no sistema de tickets do ZoL. Aparentemente, esse problema é conhecido e de alguma forma fez com que o Ubuntu e o Ubuntu o deixassem voar:

Well known problem I'm afraid. The SMB implementation that's currently in ZoL is seriously broken! I've rewritten it completely, but there is no interest what so ever to getting it merged.

Embora seja declarado como um problema bem conhecido, não parece tão bem conhecido para mim. Na verdade, estava funcionando há alguns meses e não consegui encontrar nenhum ticket para ele ou para os resultados do Google.

Falatório pessoal - pare de ler aqui se estiver satisfeito com a resposta.

Eu não sei como o Ubuntu lida com bugs como este. Eu me lembro de quando eu costumava gerenciar sistemas RedHat e eles realmente consertavam bugs no código de outras pessoas. Foi ótimo. Ter um bug "bem conhecido" no Ubuntu LTS realmente me incomoda e me faz pensar sobre todos os outros pacotes e quais outros bugs conhecidos estão sendo ignorados.

Os comentários feitos por um desenvolvedor neste relatório de bug no github são bastante interessantes. A ZoL está deixando intencionalmente bugs em seus softwares quando eles têm patches disponíveis. Patches que estavam em versões anteriores! Isso é muito decepcionante para mim. E me surpreende que o Ubuntu não aplique os patches em si, em vez de fingir que o software está funcionando e estável em sua nova versão do LTS.

Recentemente me deparei com isso depois de atualizar uma das minhas caixas de armazenamento de 14.04 para 16.04

Curiosamente, eu não encontrei isso na primeira caixa que eu atualizei, embora isso tenha sido uma re-instalação limpa, e não uma atualização distinta.

Eu achei que o principal problema era que apesar de todos os parâmetros do sharemb = on serem definidos, não havia entrada para o usershare em / var / lib / samba / usershares /

Então, acabei de criar um manualmente usando o arquivo da outra caixa como modelo, reiniciei o samba e voila, tudo funciona de novo.

Muito kludgy, embora.
