Prova con un disco nuovo. Deve funzionare.
Lo fstab =E8 a posto, te lo spieghiamo con calma al lug, nell'attesa man=
fstab:
The file fstab contains descriptive information about the various file=
=20
systems. fstab is only read by programs, and
not written; it is the duty of the system administrator to properl=
y=20
create and maintain this file. Each filesystem is
described on a separate line; fields on each line are separated=
by=20
tabs or spaces. Lines starting with '#' are com-
ments. The order of records in fstab is important because fsck(=
8), =20
mount(8), and umount(8) sequentially iterate
through fstab doing their thing.
The first field, (fs_spec), describes the block special device or=20
remote filesystem to be mounted.
For ordinary mounts it will hold (a link to) a block special devi=
ce=20
node (as created by mknod(8)) for the device to be
mounted, like `/dev/cdrom' or `/dev/sdb7'. For NFS mounts one wil=
l=20
have <host>:<dir>, e.g., `knuth.aeb.nl:/'. For
procfs, use `proc'.
Instead of giving the device explicitly, one may indicate the =
(ext2=20
or xfs) filesystem that is to be mounted by its
UUID or volume label (cf. e2label(8) or xfs_admin(8)), writing=20
LABEL=3D<label> or UUID=3D<uuid>, e.g., `LABEL=3DBoot' or
`UUID=3D3e6be9de-8139-11d1-9106-a43f08d823a6'. This will make =
the=20
system more robust: adding or removing a SCSI disk
changes the disk device name but not the filesystem volume label.
The second field, (fs_file), describes the mount point for the=20
filesystem. For swap partitions, this field should be
specified as `none'. If the name of the mount point contains space=
s=20
these can be escaped as `\040'.
The third field, (fs_vfstype), describes the type of the filesyst=
em. =20
Linux supports lots of filesystem types, such as
adfs, affs, autofs, coda, coherent, cramfs, devpts, efs, ext2, ext=
3,=20
hfs, hpfs, iso9660, jfs, minix, msdos, ncpfs, nfs,
ntfs, proc, qnx4, reiserfs, romfs, smbfs, sysv, tmpfs, udf, uf=
s,=20
umsdos, vfat, xenix, xfs, and possibly others. For
more details, see mount(8). For the filesystems currently support=
ed by=20
the running kernel, see /proc/filesystems. An
entry swap denotes a file or partition to be used for swapping, =
cf.=20
swapon(8). An entry ignore causes the line to be
ignored. This is useful to show disk partitions which are current=
ly=20
unused.
The fourth field, (fs_mntops), describes the mount options associa=
ted=20
with the filesystem.
It is formatted as a comma separated list of options. It contains=
at=20
least the type of mount plus any additional
options appropriate to the filesystem type. For documentation o=
n the=20
available options for non-nfs file systems, see
mount(8). For documentation on all nfs-specific options have a lo=
ok at=20
nfs(5). Common for all types of file system
are the options ``noauto'' (do not mount when "mount -a" is=20
given, e.g., at boot time), ``user'' (allow a user to
mount), and ``owner'' (allow device owner to mount). For more deta=
ils,=20
see mount(8).
The fifth field, (fs_freq), is used for these filesystems by the=20
dump(8) command to determine which filesystems need to
be dumped. If the fifth field is not present, a value of zero=
is=20
returned and dump will assume that the filesystem
does not need to be dumped.
The sixth field, (fs_passno), is used by the fsck(8) program to=20
determine the order in which filesystem checks are done
at reboot time. The root filesystem should be specified with =
a=20
fs_passno of 1, and other filesystems should have a
fs_passno of 2. Filesystems within a drive will be checked=20
sequentially, but filesystems on different drives will be
checked at the same time to utilize parallelism available in the=20
hardware. If the sixth field is not present or zero,
a value of zero is returned and fsck will assume that the filesyst=
em=20
does not need to be checked.
