What does sda17 mean on Linux?

Expert Solution

Answer :

It is Hard disk partition on Linux..

So, there is no possibility to create special block devices for 16-th and 17-th partition using mknod, because minor 16 will be next drive, for example:

# ls -l /dev/sda? /dev/sda?? /dev/sdb

brw-rw---- 1 root disk 8, 0 May 24 08:09 /dev/sda

brw-rw---- 1 root disk 8, 1 May 24 08:09 /dev/sda1

brw-rw---- 1 root disk 8, 2 May 24 08:09 /dev/sda2

...

brw-rw---- 1 root disk 8, 14 May 24 08:09 /dev/sda14

brw-rw---- 1 root disk 8, 15 May 24 08:09 /dev/sda15

brw-rw---- 1 root disk 8, 16 May 24 08:09 /dev/sdb
