how to mount sda16,sda17 ?

[eps]

more 15 partition on a single hdd

[Bruce B]

I've ran into this before, and fixed it with success

Code: Select all

brw-r----- 1 root root 8, 10 2011-03-25 20:09 sda10
brw-r----- 1 root root 8, 11 2011-03-25 20:09 sda11
brw-r----- 1 root root 8, 12 2011-03-25 20:09 sda12
brw-r----- 1 root root 8, 13 2011-03-25 20:09 sda13
brw-r----- 1 root root 8, 14 2011-03-25 20:09 sda14
brw-r----- 1 root root 8, 15 2011-03-25 20:09 sda15

Use mknod to add more special files in /dev

mknod --help to see how

Use chmod to set the attributes to match the others in the same major
category.

[Bruce B]

Here is howto. Commands in blue for you to actually type

cd /dev
ls -l sda* (gives this output)

If output doesn't match major then you have to change for yourself,
but I image it will match

Code: Select all

brw-r----- 1 root root 8,  0 2011-03-25 20:09 sda
brw-r----- 1 root root 8,  1 2011-03-25 20:09 sda1
brw-r----- 1 root root 8, 10 2011-03-25 20:09 sda10

brw-r----- 1 root root 8,  6 2011-03-25 20:09 sda6
brw-r----- 1 root root 8,  7 2011-03-25 20:09 sda7
brw-r----- 1 root root 8,  8 2011-03-25 20:09 sda8
brw-r----- 1 root root 8,  9 2011-03-25 20:09 sda9

mknod sda16 b 8 16
ls -l sda16 (gives this output, shows our new file)

Code: Select all

brw-r--r-- 1 root root 8, 16 2011-04-17 00:32 sda16

note attributes (at left) are not same

chmod --reference=sda15 sda16
ls -l sda* shows new special file and attributes match

Code: Select all

brw-r----- 1 root root 8,  0 2011-03-25 20:09 sda
brw-r----- 1 root root 8,  1 2011-03-25 20:09 sda1
brw-r----- 1 root root 8, 10 2011-03-25 20:09 sda10
brw-r----- 1 root root 8, 11 2011-03-25 20:09 sda11
brw-r----- 1 root root 8, 12 2011-03-25 20:09 sda12
brw-r----- 1 root root 8, 13 2011-03-25 20:09 sda13

brw-r----- 1 root root 8,  8 2011-03-25 20:09 sda8
brw-r----- 1 root root 8,  9 2011-03-25 20:09 sda9

To add more devices, repeat and increment by 1

Notice the pattern

There is block type which is b - shown at first column
Major which is 8
Minor which is shown at far right and corresponds with the file name

mknod sda16 b 8 16
mknod sda17 b 8 17
mknod sda18 b 8 18

[eps]

We have complete installation (full)
- snow-puppy sda11 016
gnome-sda15 pclos 2010.12
minimum-sda16 pclos 2010.12
Sda16 partition can not see the puppy
If you delete sda15 have everything in place but the content is the name sda15 di sda16
can now see and exploit sda15
I did this once!
normal?
I used Partition Wizard Home Edition from Hiren's cd ver 13.2
When you boot live CD 5.2 pmagic pclos or see and can operate all partitions including sda16
Using 214xtop7 linecd sda16 see displayed on the screen.

"Disks can have up to 15 partitions. See also /usr/src/linux/Documentation/devices.txt. "

http://linux.about.com/od/commands/l/blcmdl8_fdisk.htm

[myke]

eps, it seems devices.txt is a theoretical part of Linux. Using Pfind, couldn't find it in the Puppy I looked at.

In practice, my friends and I appear to be limited to four primary partitions in the partition table. Including one for a swap file, that leaves me with two fully installed Linux distros (an Ubuntu derivative, Pinguy, and another rpm-, Arch- or Gentoo-based one that changes from time to time) and one partition for Puppy as install Puppy Linuxes frugally in sub-directories (currently have six: Snowpuppy, Ice-Puppy, spup, lupu, fatdog64, Fluppy).

My friend's situation is worse. Not a Puppy lover, he has to reserve two partitions for windows and one for a swap file. He has xpud installed right now inside windows. But for bigger Linuxes, he is limited to only one primary partition to explore Linux that changes from time to time. Right now it is tails-i386 (otherwise know as Incognito Live System) so he can browse anonymously.

So both of us are far from fifteen. I heard at one time that you could take at least one of the four primary partitions and split it into extended partitions but neither one of us could figure out how to do it from gparted or even parted.

So, what tool could you use to create and manipulate extended rather than primary partitions? Hopefully for me, it is not CLI-based. I don't mind CLI in general but not when a false move could destroy a hard disk.

And I don't really want to have pen drives sticking out all over the place.

I heard at one time that you could take at least one of the four primary partitions and split it into extended partitions but neither one of us could figure out how to do it from gparted or even parted.

Using Gparted, delete one of your primary partitions. Create a new extended partition - Gparted gives you a choice of primary or extended. Inside it, create one or more logical partitions.

But there's a catch. Many (all?) BIOS's cannot boot directly off a logical partition. So you need to think about how you want your boot loader to work.

A better strategy for you might be as follows - two Windows partitions, one primary Linux partition and an extended partition that contains a logical swap partition.

[rjbrewer]

Myke;

Using gparted.
You can have 4 primaries.
Make number 4 extended, the same way you make any other
partition.
Extended contains all the remaining unused space.
New "logical", (ext2, ext3, etc.) are made the same as the earlier
partitions.

[eps]

And I felt the need to refer me to tell them sda16 and sda17
logical disks and partitions not
I repeat but were created by partition home edition from Hiren's livecd

[eps]

Do not know why I did not thought that this map of partitions be the first to be given information
While I would have won and I had less trouble!

[eps]

Using logical disks tinycore 3.6 sda16 see it as their content and sda17
