Estou trabalhando em um servidor Ubuntu de 64 bits. Eu montei um nfs como rw, mas sempre que tento editar qualquer coisa no ponto de montagem em questão, recebo um erro do sistema de arquivos somente leitura
meu etc/fstab
diz:

Arquivos no mnt são muito bem, mas sempre que tento alterar alguma coisa, recebo um erro:
touch: cannot touch '/mnt/nfs2/path/to/test_file.txt': Read-only file system
Eu posso me conectar ao nfs em questão de outros servidores e ler e escrever muito bem. O único problema está neste servidor. Eu tentei mount -o remount,rw vnxnfs1.company.com:/NFS2 /mnt/nfs2
como as respostas para perguntas relacionadas sugerem, mas sem sucesso.
Desculpe pelo despejo de dados, tentei incluir algo que pudesse gerar dicas.
EDITAR:
mais detalhes
Eu testei do usuário root
na máquina com problemas, e escrevendo para o nfs funciona de root
, bem como user
do outro servidor (nfs-write-is-working).
do servidor de trabalho: ls -la /mnt/nfs2/
