Eu tenho um servidor doméstico com um pool de três unidades, e o sistema operacional instalado em um pen drive, esse pen drive teve erros físicos e tive que reinstalar o sistema operacional, o pool LVM estava funcionando bem após o crash do pen drive, mas Eu acidentalmente selecionei uma das unidades para instalar manualmente o grub e as coisas deram errado.
Eu não sei como / porque essa unidade foi desanexada do pool e o LV parou de funcionar. Eu tentei por meses e segui guias e instruções diferentes, eu restaurei parcialmente a piscina, mas ainda não está funcionando.
O único indício que tenho agora sobre o motivo do erro é:
