How to display the raw filesystem usage.

Which command i need to use.

Thanks chandra

Hi,
I think bdf will show you the file system usages
or
df -f also show the block sizes

$ df -f /oracle/PD1/sapdata1
/oracle/PD1/sapdata1 (/dev/vg_sapdata1_new/lv_sapdata1_new): 50973312 blocks

Try this command

# bdf /dev/vgxx/rlvolxx

Hi Suraj,

Bdf and df commands will show normanl fs statistics.

But i need raw fs Statistics.

Thanks for your reply,

You are not assigning points..... Please encourage people who spend time and trying to solve your problem.

actually you can monitor the raw file system usage from the application which its using.

but from sam you can view the lvol usage. go to sam and disk and file system and select logical volumes.

Hi Ahsan,
Thanks for ur replay.

But,
I need command line options to view raw filesystem usage.

[Gokul Chandola]

Hi,
Please use sam.
When you Are Crearting file system That shows the total RAW SPACE available.
Go upto that stage but do not create YOU will get you Que's Ans.
I have done it.
BDF Shows only used and definded FS.

Sorry I have miss one point.

Please use GUI SAM for That.

As far as i know raw filesystem is not mounted. It is mainly use for database.
The only way to see utilization from unix side(space free in vg) is "vgdisplay vgname" . From oracle or database side u can see the table space utilization which s the best method to check wether allocated space to LV is totally used or not.

for normal filesystem (vxfs, HFS) u cab use "bdf" command.

Hi,
Think from BASICS.
First we are creating vg groups one or more.
this is the total difined or Total actual sapce.
Now inside the vg's we are creating FileSystem.

So we can count remaining available space for new FS of modifying existing FS.

You may use this.

AS A SINGLE COMMAND I AM WORKING ON IT. IF WILL GET SOLUTION I WILL ANS.
**BUT As a solution you have two options.

"vgdisplay vgname" is only displays the number of space allocated in the lvol. not the usage.

its only shown from the application, i.e. oracle, informix etc. etc.

Shalom

The summary here is there is really no single way to display raw disk usage. One must use the utilities that are provided with the application that owns and uses the raw disk area.

sqlplus for oracle etcetera.
