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

  • 772

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 -ae zfs share filesystemnão funcionam e por conta disso, sempre que reinicio o sistema, zfs-share.servicenão 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 sharesmbpropriedade 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 -aque 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!

  1. Best Answer

    Eu encontrei minha resposta e infelizmente não é boa

    Recebi uma resposta no sistema de tickets da ZoL. Aparentemente, esse problema é conhecido e, de alguma forma, chegou ao Ubuntu e o Ubuntu o deixou voar:

    https://github.com/zfsonlinux/zfs/issues/4999

    Problema bem conhecido, receio. A implementação do SMB que está atualmente no ZoL está seriamente quebrada! Eu o reescrevi completamente, mas não há nenhum interesse em fundi-lo.

    Embora seja declarado como um problema bem conhecido, não parece tão conhecido para mim. É fato que estava funcionando há alguns meses e não consegui encontrar nenhum tíquete para ele ou resultados do Google.

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

    Não sei como o Ubuntu lida com bugs como esse. Lembro-me de quando costumava gerenciar sistemas RedHat e eles realmente corrigiam bugs no código de outras pessoas. Foi ótimo. Ter um bug "conhecido" no Ubuntu LTS realmente me incomoda e me faz pensar sobre todos os outros pacotes e quais outros bugs conhecidos estão lá que estão sendo ignorados.

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

  2. Recentemente, descobri isso depois de atualizar uma das minhas caixas de armazenamento de 14.04 para 16.04

    Curiosamente, não encontrei isso na primeira caixa que atualizei, embora tenha sido uma reinstalação limpa e não um dist-upgrade.

    Descobri que o principal problema era que, apesar de todos os parâmetros do sharemb=on estarem 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 pronto, tudo funciona novamente.

    Muito kludgy, embora.
