Não é possível acessar o Windows Share no Netapp a partir do Xubuntu 14.04 usando o Samba

Question

desde que eu costumava montar o compartilhamento de samba no Netapp com um comando como:

mount -t cifs //netapp.dns.name/myshare /home/myhome/myshare --verbose -o credential=/home/myhome/.credential,sec=ntlm,iocharset=utf8,dir_mode=0777,file_mode=0666,nounix,noserverino

Na semana passada, estava tudo bem, mas na segunda eu recebi este erro:

domain=MYDOMAIN
mount.cifs kernel mount options: ip=10.nnn.nnn.nnn,unc=\netapp.dns.name\my.login,sec=ntlm,iocharset=utf8,dir_mode=0777,file_mode=0666,nounix,noserverino,user=olivier.savoye,,domain=MYDOMAIN,pass=********
mount error(5): Input/output error
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Aqui estão as mensagens do syslog:

Não vejo nada que possa afetar minha montagem cifs, exceto (talvez) o pacote libgcrypt11.

Eu não tento removê-lo para um mais velho porque não tenho certeza se ele pode ajudar.

Alguém poderia me dar algum conselho?

    

Answer 1

Eu tenho o mesmo problema com um compartilhamento ONTAP.

Eu acho que isso está relacionado a esse bug: link

Usar o fusível com o kernel 3.13.0-36 funciona bem.

Usar o fusível ou mount.cifs com o kernel 3.13.0-35 funciona OK.

Portanto, parece que há um problema no kernel 3.13.0-36 com o cifs-utils.

Eu tentei o kernel 3.13.0-37.44 do link da Canonical Kernel Team sem sorte. O mesmo erro.

Como solução alternativa, alterei o kernel padrão para 3.13.0-35 com este guia: Defina o kernel "mais antigo" como entrada padrão do grub

    

Answer 2

Eu enfrentei o mesmo problema esta semana, com a mesma mensagem de saída, assim como a que você encontrou no syslog. Eu não uso um Netapp, mas um simples NAS mundial do Western Digital My Book.

Em paralelo, eu tenho um Synology NAS DS414 que eu posso montar seus compartilhamentos cifs sem qualquer problema.

Eu também fiz algumas atualizações recentes. Como parte deles: o kernel; uma atualização de 3.13.0-35-genérico para 3.13.0-36-genérico.

Eu recuo meu sistema com o kernel 3.13.0-35-genérico e tudo funcionou bem novamente.

Ainda não entendi por que consegui montar os compartilhamentos da Synology, e não os da Western Digital. Só que meu Western Digital usou uma versão antiga do samba. Versão de compatibilidade? Regressão do kernel? Eu não sei !!!

    

Answer 3

Resolvido com o linux-image-3.13.0-37-generic.
