Esperando que alguém possa me ajudar.
Estou tentando exportar meu pool do ZFS para que eu possa atualizar meu Ubuntu de 14.04 para 15.10.
Eu tentei fazer o-release-upgrade e perdi meu pool, ao descobrir instruções, reverti para o backup e tentei exportar o pool primeiro.
No entanto, estou recebendo este erro:
# sudo zpool export -f mynas
umount: /mynas: target is busy
(In some cases useful info about processes that
use the device is found by lsof(8) or fuser(1).)
cannot unmount '/mynas': umount failed
Então, tentei usar o fusor e obtive uma pilha de IDs de usuário usando o pool.
# sudo fuser -c /mynas
/mynas: 3519m 3521m 3535m 3560m 3562m 3565m 3566m 3567m 3568m 3569m 3571m 3582m 3670m 3715m 3719m 3727m 3737m 3754m 3755m 3759m 3794m 3796m 3798m 3858m 3859m 3912m 3945m 3947m
Eu tentei matar todos eles, mas isso mata até mesmo minha sessão ssh, e quando eu reinicio a sessão, eu ganho uma pilha mais ids '
Alguma ideia? Muito obrigado.
[Editar]
Além disso, eu tentei matar id's usando lsof / mynas para id proceces, todos exceto ssh ids, mas ainda recebo a mesma mensagem de erro / falha: (
