Descobri um problema estranho ... se eu tenho DMGs (arquivos de imagem de disco) que residem em um compartilhamento NFS somente leitura, não consigo abri-los no Mac OS X 10.7.5. Os mesmos arquivos abrem bem quando acessados pelo AFP. No entanto, tentar abri-los usando hdiutil attach
o compartilhamento NFS resulta em "falha na conexão - sistema de arquivos somente leitura":
bash-3.2# /usr/bin/hdiutil attach /Volumes/nfs_share/Some.dmg
hdiutil: attach failed - Read-only file system
Mesmo que o compartilhamento AFP seja somente leitura, posso anexar essas mesmas imagens. Mas, por algum motivo, um compartilhamento NFS somente leitura não funciona.
Em última análise, o que eu quero fazer é anexar as imagens com um arquivo de sombra , para montar as imagens somente leitura como leitura e gravação. Mas isso também falha da mesma maneira:
bash-3.2# /usr/bin/hdiutil attach /Volumes/nfs_share/Some.dmg -mountpoint /Somewhere -shadow /path/to/Some-Shadow
hdiutil: attach failed - Read-only file system
Novamente, isso funciona perfeitamente se a imagem é veiculada via AFP. Também funciona bem se o compartilhamento NFS for de leitura e gravação, mas por motivos de segurança, não posso fazer isso.
Como montar arquivos DMG que residem em um compartilhamento NFS somente leitura?
