Movendo LVM para outro sistema Linux. 1 – Desmontar o file system Inicialmente devemos desmontar os sistemas de arquivos que estão sob o VG que será migrado. Assim, você garante que nada tentará escrever na área que será movimentada. # unmount /data/www 2 – Mark the volume group inactive Vamos marcar o VG como inativo removendo ele do kernel, isso é para prevenirmos que quaisquer atividades tentem ativá-lo novamente. # vgchange -an webdata vgchange — volume group “webdata” successfully deactivated 3 – Exportar o VG It is now necessary to export the volume group. This prevents it from being accessed on the “old” host system and prepares it to be removed. Nesta etapa é necessário exportar o VG para ser levado ao novo servidor. O servidor antigo também “fica preparado” para sua remoção. # vgexport webdata vgexport — volume group “webdata” successfully exported Na próxima vez que o sistema operacional for reiniciado, os discos poderão dês desconectados e ...
