ram dsisk

Recommended Posts

Salve a tutti !


Come da titolo stò cercando di creare un ram disk sul mio pc con ubuntu .


Ho seguito la guida presente sul sito http://www.hostingtalk.it/utilizziamo-i-ram-disk-per-velocizzare-il-sistema_-c000000yn/


è andato tutto bene fino a quando non sono andato a dare questo comando : sudo mount -t tmpfs –o size=128M tmpfs /mnt/ramdisk , che non viene riconosciuto e non capisco il perchè ....  :(



Usage: mount -V                 : print version

       mount -h                 : print this help
       mount                    : list mounted filesystems
       mount -l                 : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
       mount -a [-t|-O] ...     : mount all stuff from /etc/fstab
       mount device             : mount device at the known place
       mount directory          : mount known device here
       mount -t type dev dir    : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
       mount --bind olddir newdir
or move a subtree:
       mount --move olddir newdir
One can change the type of mount containing the directory dir:
       mount --make-shared dir
       mount --make-slave dir
       mount --make-private dir
       mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
       mount --make-rshared dir
       mount --make-rslave dir
       mount --make-rprivate dir
       mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using  -L label  or by uuid, using  -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say  man 8 mount .


la directory in mnt è creata correttamente . 


Dato che che ci sono mi potet dare anche la riga da aggiungere a fstab per montare il ram disk al boot ? :lode:
