How to find whether the logical volume is formatted or not formatted

[senthil_kumar_1]

Hi All,

I have one logical volume, i want to find if that is formatted or not formatted.

[Patrick Wallek · Accepted solution]

Run the 'fstyp' command against the LV.

For example:

# fstyp /dev/vg00/lvol6
vxfs

This output means that /dev/vg00/lvol6 has a vxfs file system on it.

If by "formatted" you mean a filesystem structure, you can use the "fstyp /dev/vgXX/lvolYY" command

There is no other formatting on logical volumes.

You can issue the command fstyp against that logical volume and it will give the file system type you have.

But I feel you want to know how to find out the logical volume is empty or not. Am I right?

Shalom,

format is not a useful term here.

lvdisplay lvol_name
#or
lvdispaly -v lvol_name

To see if anything is on it.

Hey Senthil,

formated is a windows Term. In unix, you can say if it has an FS on it or not.

to find that you can use command

# fstyp /dev//

or

# lvdisplay /dev//

No such thing in UNIX

lvdisplay -v /dev/vgxx/lvolxx

or fstype -v

Thanks,
Johnson
