Eu tenho uma unidade criptografada que eu montei na minha instalação do Ubuntu 17.10. Quando eu primeiro descriptografar o contêiner e montar a partição, ele aparece como 'rw' na montagem (saídas detalhadas abaixo). Assim que tento escrever qualquer coisa, recebo um erro que diz que é um sistema de arquivos somente para leitura e é exibido como 'ro' no mount. Eu posso ler os arquivos na unidade muito bem.
Não tenho certeza se isso é importante, mas se isso acontecer, essa instalação do Ubuntu 17.10 está sendo executada dentro do Virtual Box. A unidade externa está sendo conectada à máquina por meio de um controlador de armazenamento virtual USB que acessa um disco .vmdk apontando para a unidade. A unidade não seria montada sem a opção 'Usar cache de E / S do host' selecionada.
Abaixo estão algumas informações do terminal, incluindo mount e fdisk. Eu mudei para root para pular digitando no sudo para cada comando. Não é assim que eu normalmente corro.
Agradecemos antecipadamente e deixe-me saber se há mais comandos de diagnóstico que eu devo mostrar.
Solução de problemas:
Conecte o disco rígido e use o utilitário 'Disks' para desbloquear a partição, mas não para montá-la. Eu recebo o seguinte (cortando as informações sobre os outros discos):
root@ubuntu-17-10-vm:~# fdisk -l

Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Neste ponto, "mount | grep luks" não retorna nada. Agora, seleciono o botão 'Mount Selected Partiton' no utilitário Disks e tentamos o fdisk e o mount novamente:

Eu tento criar um diretório e sou impedido:
root@ubuntu-17-10-vm:~# cd /mnt/3TB
root@ubuntu-17-10-vm:/mnt/3TB# mkdir Temp
mkdir: cannot create directory ‘Temp’: Read-only file system
Em seguida, vamos ver o mount novamente e a partição é somente leitura:
root@ubuntu-17-10-vm:/mnt/3TB# mount|grep luks
/dev/mapper/luks-3ac27466-39e7-49b9-875c-db8953433731 on /mnt/3TB type ext4 (ro,nosuid,nodev,relatime,data=ordered,x-gvfs-show)
A entrada fstab para este dispositivo é bastante genérica:
/dev/disk/by-label/3TB /mnt/3TB auto nosuid,nodev,nofail,x-gvfs-show 0 0
Alguma ideia? Alguma sugestão sobre o que mais copiar / colar aqui para ajudar a identificar o problema?

Aqui está o texto pertinente do arquivo syslog em vários pontos. Isso ocorre antes que a unidade USB esteja ligada após uma inicialização limpa.
