Estou executando o Fedora Server Edition 26 e tenho duas unidades USB externas com uma partição em cada uma que combinei no RAID1. Meu arquivo / etc / fstab tem essa linha para automontar a matriz:
UUID=B0C4-A677 /mnt/backup-raid exfat uid=strwrsdbz,gid=strwrsdbz,umask=022,windows_names,locale=en.utf8,nobootwait,nofail 0 2
No entanto, quando a inicialização é concluída, a matriz em / mnt / backup-raid não é montada. Se eu verificar os logs do diário, vejo

Portanto, parece que ele é montado no primeiro bloco de log, mas depois é desmontado porque está aparecendo como degradado. Mas assim que terminar a inicialização, posso executar sudo mount -a e as montagens da matriz sem problemas. O conteúdo aparece corretamente em / mnt / backup-raid e verifica / proc / mdstat mostra
Personalities : [raid1]
md0 : active raid1 sdc2[0] sdb2[2]
485345344 blocks super 1.2 [2/2] [UU]
bitmap: 0/4 pages [0KB], 65536KB chunk
unused devices: <none>
tudo parece saudável. Caso isso ajude, meu /etc/mdadm.conf contém
ARRAY /dev/md0 level=raid1 num-devices=2 metadata=1.2 name=hostname:backup-raid UUID=6c8bf3df:c4147eb1:4c3f88d8:e94d1dbc devices=/dev/sdb2,/dev/sdc2
Eu encontrei este tópico de e-mail que parecia estar lidando com um problema semelhante situação, mas parece-me que apenas ficou em silêncio. Me desculpe se a resposta está nesse segmento de e-mail e eu perdi, mas fica um pouco densa demais para eu seguir.
