Solaris 11: Log de Pools do ZFS

Solaris 11: Log de Pools do ZFS

Quando foi criado um Pool do ZFS? Quando tivemos problemas no espelhamento?

Toda a vida de um Pool ZFS pode ser verificada pelo comando zpool history, desde sua criação, até parâmetros alterados e manutenções executadas.
Se utilizado com um Pool como argumento do comando, retorna apenas dados deste Pool. Caso contrário, retorna de todos.
