[SOLVED] knowing about partitions in fdisk command

sachin.davra · 12-22-2014, 01:44 AM

Hi, i am using centos 6 x64.

Here is my fdisk table

Code:

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          32      256000   83  Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2              32        6560    52428800   83  Linux
/dev/sda3            6560        7082     4194304   82  Linux swap / Solaris
/dev/sda4            7082       14588    60296192    5  Extended
/dev/sda5            7082       14588    60295168   8e  Linux LVM

I want to know where sda5 is mounted.

my mount points are

Code:

[root@swift ~]# mount
/dev/sda2 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")
/dev/sda1 on /boot type ext4 (rw)
/dev/mapper/VolGroup-LogVol00 on /home type ext4 (rw)
/dev/mapper/MYSQLDATA-mysqldata on /MYSQL type ext4 (rw)
/dev/mapper/DATA-data on /data type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
nfsd on /proc/fs/nfsd type nfsd (rw)
/dev/sde1 on /mnt type ext3 (rw)

I want to know where sda5 is mounted.

nowhere, actually, because it isn't a file system of its own. Instead, it's a container for volumes controlled by the LVM, a bit like the extended partition in /dev/sda4, which is also just a container - you won't find /dev/sda4 mounted anywhere. Looking at the list of your mount points, I see:

Code:

/dev/mapper/VolGroup-LogVol00 on /home type ext4 (rw)
/dev/mapper/MYSQLDATA-mysqldata on /MYSQL type ext4 (rw)
/dev/mapper/DATA-data on /data type ext4 (rw)

These seem to be the volumes contained in /dev/sda5.

I got your point. Actually there are more couple of disks which are formated as lvm. I checked those. Thanks for your valuable time. It resolved my querry.
