How to check the type of partition?

**rah_jad** · 02-24-2009

I have 2 hard drives wth below configuration:-
device ID System

sda1 83 linux
sda2 8e linux LVM
sdb1 83 linux

I want to check what type of partition is there. is it ext2 or ext3?
Is there any command to check the typw of partition?

this isn't the type of partition, just the filesystem type, the easiest way I can see to figure it out is to

Code:

cat /etc/fstab

Code:

df -T

will show you file system type in the second column of output (for mounted partitions).

Here my real issue:-
I ahve added new hard drive in the machine
I used fdisk to create partion and mkfs to initilze it now when I use "mount -t ext3 /dev/sdb1 /jadon/hdd" it fails. So I have to mount it manually and did the entry in fstab? I want to know why "mount -t ext3 /dev/sdb1 /jadon/hdd" is not working?

Could you post exact error message here? Which code did you add in /etc/fstab for it?

**rah_jad** · 02-25-2009

There is no such error message. It show thw option to use with "mount". The entry which is done is fstab is :-
/dev/sdb1 /jadon/hdd ext3 default 1 1

Are you attempting to mount it as root or a normal user?

Here is the A to Z of my issue.

I am running a RHEL 5 on vmware workstation 6.5. I have added another virtual drive in it. so there 2 virtual drives of 6 GB each. I tried to add the new VD by running "fdisk /dev/sdb" and then "mkfs" and then "mount -t ext3 /dev/sdb1 /jadon/hdd", but the mount command didnt ran and gave no output. Then I did a manual entry in "fstab". I am doing all this as root.

Question:- Why "mount -t ext3 /dev/sdb1 /jadon/hdd" didnt worked?

Now when I rebooted the VM, I found that new virtual hard drive (hdb) is not mounted on its folder, then I check the "fstab". The file was as it is and "sdb" information was there in it. Then I ran "mount -t ext3 /dev/sdb1 /jadon/hdd" and it worked this time. the new hard drive (sdb) got mounted on it folder.

Question:- Why the new hard drive(sdb) unmounted automatically and when I ran "mount -t ext3 /dev/sdb1 /jadon/hdd" It got mounted? Why?
