Creating Volumes

Jagadesh — Fri, 08 Aug 2003 13:43:22 GMT

Is it possible to create logical volumes in SAM with out giving the mount point. It is asking for the mount point when i try to create Logical volume.

I need to create a logical volume first and at later point of time i need to mount the same.

Kindly help me out in this.
Thanks & Regards
Jagadesh

Hi Jagadesh,

Nope - not in SAM.
It wants to do the *complete* process.
To do what you want, you'll have to do it command line:
Create the LV
lvcreate -L xxxx -n lv_name vg_name #where xxxx=size in MB

Create the filesystem
newfs -F vxfs /dev/vg_name/rlv_name

Then you can mount it whenever.

HTH,
Jeff

If you are going to use SAM to do this then the easist way is to simply select "None (Raw)" for usage when you create the LVOL. You can always then come back later and create a filesystem and define the mountpoint.

# lvcreate -L ??? -n lvol? /dev/vg??
# newfs -F vxfs /dev/vg??/rlvol?

no mount at this time

later time create mount point.

# mkdir /??????
# mount /dev/vg??/lvol? /??????

Hope it helps,

Robert-Jan.

Hi Jagadesh,

If you want to use SAM only then u can not avoid giving a mount point .

What you can do is give a mount point and in the FS options select mount on boot option.

And after creating the LV , SAM will put an additional line in fstab.Just vi fstab and remove that entry thats all.

The file system will be created , but it will not be mounted unless you do it manually.

Regds,
