Oi eu sou novo no Ubuntu e quero aprender (na verdade, estou usando há algum tempo, mas muitos contratempos e progresso lento).
Eu tenho alguns problemas onde as partições aparecem no Nautilus, mas não no nautilus gksudo. Estou usando gksudo nautilus porque eu não tenho acesso root às minhas partições, possivelmente problemas ligados a etc / fstab
Eu pesquisei no Ubuntu e encontrei algumas informações realmente úteis. Parece que um etc / fstab normal ficaria assim: -
/dev/hda2 / ext2 defaults 1 1
/dev/hdb1 /home ext2 defaults 1 2
/dev/cdrom /media/cdrom auto ro,noauto,user,exec 0 0
/dev/fd0 /media/floppy auto rw,noauto,user,sync 0 0
proc /proc proc defaults 0 0
/dev/hda1 swap swap pri=42 0 0
mas o meu é assim: -
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sdc1 during installation
UUID=617469bb-1180-4678-8274-5f88084f7162 / ext4 errors=remount-ro 0 1
# swap was on /dev/sda3 during installation
UUID=fc44ce96-8676-46c6-be06-0113bbc716de none swap sw 0 0
# swap was on /dev/sdc2 during installation
UUID=6251911e-b45b-444a-9ac5-c365cb8dca5e none swap sw 0 0
Qualquer ideia, por favor, pessoal
Leia man fstab . Seu fstab está OK. Usa UUIDs para identificar partições, em vez de /dev/ caminhos. Você mostra:
/ mounted on UUID 617469bb-1180-4678-8274-5f88084f7162 (was /dev/sdc1 at installation)
swap on UUID fc44ce96-8676-46c6-be06-0113bbc716de (was /dev/sda3 at installation)
swap on UUID 6251911e-b45b-444a-9ac5-c365cb8dca5e (was /dev/sdc2 at installation).
/etc/mtab mostra o que está montado neste instante, /etc/fstab mostra o que será montado.
Parece que você está confundindo duas coisas. Agora isso é normal (como você chamou) fstab :
cat /etc/fstab :
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda2 during installation
UUID=43bdfb68-9917-4937-aa5a-932bd2a94c98 / ext4 errors=remount-ro 0 1
# /boot/efi was on /dev/sda1 during installation
UUID=B35B-35B8 /boot/efi vfat defaults 0 1
# swap was on /dev/sda3 during installation
UUID=e0ca0a52-fd55-459f-820a-be3531e21800 none swap sw 0 0
# file syc between ~/www and /var/www/html
/var/www/html /home/george/www none bind 0 0
/var/cache/swap/kswap none swap sw 0 0
Agora, o que é realmente montado com cat /etc/mtab :

Você OP título How to fix / reconstruct corrupt fstab Ubuntu 16.04 to regain access to partitions , você não faz isso enquanto está montado você tem que desmontá-lo para obter acesso. Um liveCD usando gparted tornaria isso possível, MAS ROSCA LIGEIRAMENTE as it appears you quit a novice. Try using a Máquina Virtual 'para ter uma idéia de todos os possíveis problemas que você terá e poderá enfrentar ao tentar isso.
ATENÇÃO as partições podem ser diferentes do que mostrei aqui, por favor executem esses comandos e eles mostrarão suas partições como você as configurou anteriormente quando instalou Ubuntu
