[SOLVED] SDA Partition

JJJCR · 10-27-2011, 02:53 AM

hi, i had this info on my centos box:

Quote:

[dsk@mycomp ~]$ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda3 144115220 8903832 133723612 7% /
/dev/sda1 194442 16884 167519 10% /boot
tmpfs 1556852 0 1556852 0% /dev/shm

Quote:

[dsk@mycomp ~]$ cat /proc/partitions
major minor #blocks name

8 0 243163136 sda
8 1 200781 sda1
8 2 6289447 sda2
8 3 148777965 sda3

as you can see from the df output only /dev/sda3 and /dev/sda1 is listed.

Where is sda2? why it's not displayed on df output.

thanks for any explanation

sda2 will be an extended partition..

Also, please use code tags.
It REALLY does make a post 10x easier to read.

Best may be to run gparted application where you can exactly see the name, size, position and type of all partitions.

It is not an necessarily an extended partition. I would say it is swap which is not mounted like a regular partition and therefore not displayed via df.

As suggested you can use gparted or any of the other disk utilities like fdisk, sfdisk.

hi michaelk, yes you're right it's a swap partition. i tried to use fdisk -l then it shows as a swap.

thanks.

Good point, completely missed that one.
